Description

[0001] Caseless bolt-action weapon

[0002] The present invention relates to firearms, namely to caseless bolt-action weapons, and can be used in the creation of designs for firing caseless ammunition.

[0003] While designs with propellant contained within the bullet were developed in the US for the Volkanik 1860 and Gyroyjet 1965 weapons, their drawbacks include low ammunition yields of no more than 250 J and insufficient accuracy. The proposed invention places the propellant within the projectile. This, coupled with the design features of the weapon and the projectile, allows for a higher ammunition yield of up to 3,500 J.

[0004] A group of inventions is known that relates to caseless weapons for magazine, semi-automatic and automatic shooting according to patent UA 120290 (IPC F41C7 / 00 and others, published on March 25, 2019) containing: a removable front sight, a removable diopter sight, a front grip, a butt, a magazine, a receiver cover, a cocking lever, a cocking lever axis, a cocking lever axis counter-washer, a cocking lever spring, a bolt carrier A or B, a rod, a rod spring, a firing pin-piston, a conical bolt sleeve, a bolt body, a firing pin retainer, a firing pin spring, a compensator, a compensator washer spring, a barrel with a smooth bore, a barrel retainer, a multifunctional cartridge, a conical receiver sleeve, an extractor, an extractor counter-washer, a receiver, a trigger box B or B, front large nut, front sling swivel, magazine catch, magazine catch follower, safety catch spring, safety catch, safety,trigger rod for semi-automatic fire or for automatic fire, sear, trigger rod spring, firing mechanism bracket, hammer axis, spiral mainsprings, hammer or, multi-function latch lever, multi-function latch stop, stop cotter pin, stop cotter pin spring, cleaning rod lock, cleaning rod lock spring, cleaning rod, caseless ammunition.

[0005] Certain military missions require a highly accurate single shot, along with a quiet reload. This can only be achieved with a weapon based on a magazine-fed rifle with a rotating bolt handle, which is the simplest in terms of its components and mechanisms. The disadvantage of this solution is that: this group of caseless weapon inventions lacks a classic magazine-fed rifle with a rotating bolt handle, and the use of complex and expensive designs for a highly accurate single shot is impractical.

[0006] A group of inventions is known that relates to a caseless magazine-fed weapon according to patent UA 124985 (IPC F41C7 / 00 and others, published on 12 / 23 / 2021), consisting of: a stock, a magazine, a barrel, a barrel latch, a multifunctional cartridge, a conical sleeve of the receiver, a receiver, a safety spring, a safety, a trigger guard with a magazine box, a trigger, a trigger spring, a magazine catch, an axis, a striker, a striker latch spring, a striker latch, a conical sleeve of the bolt, a bolt body, a firing pin, a mainspring, a mainspring latch, a skeletal butt, an adjustable butt plate, an upper screw, a lower screw, a caseless ammunition, an adjustable butt plate latch, an adjustable cheek, an adjustable cheek latch, a lower part of the muzzle brake, an upper parts of the muzzle brake, muzzle brake screw.

[0007] The disadvantages of this group of inventions are:

[0008] A trigger mechanism consisting of a trigger freely attached via a pin in the trigger guard and magazine housing, and a magazine catch freely swinging within the trigger guard and magazine housing. These are connected by a trigger spring, one end of which presses the trigger, and the other end presses the magazine catch. When the trigger mechanism is mounted on the weapon, the trigger, compressed by one end of the trigger spring, rests against the receiver and engages the bolt's firing pin during operation, while the other end of the trigger spring compresses the magazine catch and engages the magazine, securing it within the magazine housing and trigger guard. The disadvantage of this solution is that the trigger pull cannot be adjusted, and in sniper weapons, a variable trigger pull from 1 kg to 3.5 kg is desirable for different firing missions.

[0009] The multifunctional cartridge consists of a smooth inner sleeve, a threaded inner sleeve, a middle sleeve, and an outer sleeve. The multifunctional cartridge falls into the first and second groups of inventions.

[0010] The disadvantage of this design of the multifunctional cartridge is that at high pressures, the difference in the combined deformations of the smooth inner sleeve, the middle sleeve and the outer sleeve, and at the same time the difference in the combined deformations of the threaded sleeve, the middle sleeve and the outer sleeve create increased stress at the junction of the smooth inner sleeve and the threaded sleeve, which leads to the destruction of the multifunctional cartridge at certain pressures.

[0011] The first and second groups of inventions feature a joint between the conical sleeve of the chamber and the multifunctional cartridge. When a shot is fired, this joint opens due to high gas pressure, and gases enter the chamber. This joint, located at the end surfaces of the conical sleeve of the bolt and the multifunctional cartridge, creates a high tensile force on the chamber. This requires high-strength materials. It is advisable to seal this joint and relieve the chamber.

[0012] In the first and second groups of inventions, the caseless ammunition on the igniter side extends some distance into the conical sleeve of the bolt. When fired, the high pressure in the projectile chamber often forces metal from the outer wall of the projectile chamber into the resulting gap, causing a transverse rupture of the projectile. After firing, a small portion of the projectile on the igniter side remains in the conical sleeve of the bolt, causing a difficult-to-resolve delay and requiring disassembly of the weapon. It is desirable to eliminate this drawback.

[0013] In magazine-fed weapons belonging to the second group of inventions, the trigger spring acts on the trigger with one end and on the magazine catch with the other. It has no way to adjust the trigger pull or the magazine catch. For sniper shooting, it would be desirable to be able to adjust the trigger pull while maintaining reliable operation of the magazine catch.

[0014] In a magazine-fed firearm, the piston striker, when striking the primer, creates a gap between the piston end and the thick wall of the conical bolt sleeve. When fired, gases press on the igniter block of the caseless ammunition and transmit force to the piston striker, which in turn eliminates the gap between the piston end and the thick wall of the conical bolt sleeve. This generates a large force impulse, which is transmitted to the firing pin. The firing pin recoils within the bolt and is dampened by the mainspring, the flag with the guide rod, and the rear of the bolt body. This group of components requires high strength, yet their service life is short. Furthermore, the return spring, located on the piston striker, quickly settles due to the high-speed force impulse and fails. It is advisable to move the firing pin to the firing pin.

[0015] In a magazine-fed weapon, when the safety is set to the "safe" position and removed from that position to the "fire" position, the safety catch describes an arc against the optical sight, requiring an increased sight mount height. It would be desirable to address this drawback.

[0016] When the hammer is cocked and the safety is in the "safe" position, a hole in the receiver where the safety operates opens from the safety tab. This allows dirt and debris to enter the receiver through this hole, reducing the weapon's reliability. When the safety is in the "fire" position, a hole in the rear of the bolt from the safety tab opens, allowing dirt and sand to enter the internal bore of the bolt, preventing proper operation of the bolt and, in turn, reducing the weapon's reliability. It is advisable to address this issue.

[0017] The mainspring is located in the firing pin, which is inserted into the bolt body and secured in the firing pin grooves by the mainspring retainer. However, when the bolt is operating, dirt and sand can enter these grooves. It is advisable to address this issue.

[0018] The dowel screws through the trigger guard secure the receiver to the stock and chamber, creating the necessary rigidity in the weapon. However, during assembly, the tightening force of these screws varies from one shooter to the next, requiring the weapon to be sighted in after each disassembly and assembly. It's preferable to use components that don't require re-sighting after each disassembly.

[0019] To make the weapon lighter, it is advisable to make the receiver from light alloys and the chamber from steel, which will make the weapon lighter and improve its performance properties.

[0020] When carrying magazine-fed weapons in infantry fighting vehicles (IFVs), it's advisable to reduce their dimensions. To achieve this, a folding stock should be used that doesn't exhibit play in the folding joints during prolonged use. This is especially important for sniper weapons, as play in the folding joints reduces accuracy.

[0021] It's advisable to keep the ejection port closed when firing. This will prevent dirt and debris from entering the weapon during operation, improving its reliability.

[0022] The objective of the proposed invention is to create a high-precision caseless bolt-action weapon that will improve operational characteristics, namely: increase the reliability of the weapon in difficult conditions, ensure the convenience of eliminating minor delays and facilitating loading and unloading, ensure the reliability of the weapon in combat conditions with a forced supply of ammunition, including contaminated ones, improve the stability of the projectile trajectory and ensure increased accuracy of firing the weapon from stable positions and at the hip.

[0023] The second objective of the invention is to create a new design for a caseless bolt-action weapon that will eliminate recoil, increase firing efficiency, reduce heat loss, reduce barrel heating, and improve the safety of the weapon and shooters.

[0024] When using caseless bolt-action weapons, it is desirable to increase the efficiency of the shot, reduce the weight and dimensions of the weapon, increase the safety of the weapon and the shooter, and improve the stability of the projectile's flight along the entire trajectory.

[0025] When using caseless bolt-action weapons, it is advisable to reduce the cocking force and make loading the weapon easier.

[0026] When using caseless bolt-action weapons, it is desirable to facilitate extraction and increase its reliability.

[0027] The stated objectives are achieved with the help of the proposed caseless bolt-action weapon according to independent claim 1, and other desirable implementation options of which are defined in the dependent claims of the formula.

[0028] In the proposed weapon, the simplification of cocking, loading and unloading is achieved by the fact that: when opening the bolt 63 after a shot, there is no caseless ammunition 51, and in the event of a misfire, the caseless ammunition 51 has a free gap 323 between the walls of the smooth cartridge 44, taking into account the taper of the conical sleeve of the bolt 42, which ensures easy extraction of the caseless ammunition 51 and facilitates unloading of the weapon with the help of the manual extractor rod 29;

[0029] - the mainspring 38 is cocked when the bolt 63 is opened using the bolt handle 26 as a lever, while the absence of caseless ammunition 51 reduces the cocking force and makes loading the weapon easier.

[0030] Ensuring the reliability of the weapon in combat conditions, with the forced feeding of caseless ammunition 51, including contaminated ones, is achieved by the fact that: during manual feeding, including contaminated caseless ammunition from the magazine 15 into the smooth cartridge 44, the caseless ammunition 51 has a free gap 323 between the walls of the smooth cartridge 44, this increases the reliability of the weapon in combat conditions. A distinctive feature of the proposed invention is that, when fired, the caseless ammunition 51 is surrounded by a large mass of metal: a smooth cartridge 44, a rifled cartridge 45, a receiver 1, a gun chamber 17 and a bolt 63. The projectile 318 has a wall thickness 1.5-2 times greater than the wall of the cartridge case in a traditional weapon, which provides greater thermal inertia, and the free gap 323 between the walls of the smooth cartridge 44 and the walls of the projectile 318 itself reduces the contact zone for the transfer of thermal energy from the heated smooth cartridge 44 to the projectile 318.Thus, the moment of spontaneous combustion of caseless ammunition 51 inside a heated weapon is significantly delayed.

[0031] A distinctive feature of the proposed invention is that manufacturing the smooth-bore three-layer cartridge 44 and the rifled three-layer cartridge 45 separately eliminates the problem of deformation, allowing the smooth-bore and rifled cartridges to deform independently, relieving stress between the cartridges and allowing them to withstand greater pressures than when they are manufactured as a single unit. This improves the reliability and safety of the weapon as a whole.

[0032] A distinctive feature of the proposed invention is that a conical annular groove 175 is formed at the end of the small base of the conical bore 174 of the conical sleeve of the gun chamber 43, which interacts with the conical annular projection 169 of the smooth cartridge 44. This prevents gases 320 from breaking through into the space between the end surface of the conical sleeve of the gun chamber 43 and the end surface of the smooth cartridge 44 in the gun chamber 17 during firing. This reduces the forces on the gun chamber 17, which reduces the strength requirements for the materials and increases the reliability of the weapon. A distinctive feature of the proposed invention is that the platform 90 of the guide rod of the conical sleeve of the bolt 41 is located in the cross-sectional plane of the end of the small base 98 of the conical sleeve of the bolt 42.In this case, the rear part of the projectile 318 rests against the platform 90 of the guide rod of the conical sleeve of the bolt 41 and is extended beyond the joint of the conical sleeve of the gun chamber 43 and the smooth cartridge 44, which eliminates the transverse break in the rear part of the projectile 318 when fired.

[0033] A distinctive feature of the proposed invention is that the trigger guard is equipped with an adjusting screw for the trigger spring 46 and an independent trigger spring 47 that interacts with the trigger 28, and the magazine catch 27 has its own separate magazine catch spring 48.

[0034] A distinctive feature of the proposed invention is that in the guide rod of the conical sleeve of the bolt 41 a through cylindrical hole 95 is made for the striker 39, and the striker 39 is fixed in the firing pin 36, while the guide rod of the conical sleeve of the bolt 41 is rigidly fastened with the conical sleeve of the bolt 42 into one piece, and they are installed and fixed in the housing of the bolt 4 by the lock of the guide rod 40. And at the same time, in the guide rod of the conical sleeve of the bolt 41, when firing, the pressure of gases 320 is transmitted on one side from the ignition unit 315 through the guide rod of the conical sleeve of the bolt 41 and the conical sleeve of the bolt 42 to the lugs of the housing of the bolt 4, and on the other side through the striker 39 to the firing pin 36, which allows most of the impulse received from the pressure of gases 320 is transferred to the combat stops 66, and only a small part through the striker 39 to the firing pin 36.Moreover, the guide rod of the bolt cone bushing 41 lacks a spring, which improves the reliability of this assembly and the firing pin 36, as well as reduces the strength requirements for the materials and enhances the weapon's reliability. A distinctive feature of the proposed invention is that the safety catch 31 is located on the side wall of the receiver 1, and its entire operation occurs within a small sector, which does not interfere with the installation of sights on the weapon.

[0035] A distinctive feature of the proposed invention is that the fuse 31 is located on the axis of the fuse 52 and is spring-loaded by the spring of the fuse 53, which is located on the axis of the fuse 52, and is fixed through a through hole 222 by the axis of the fuse 52 in the bracket of the fuse 24, which makes it possible to perform reciprocating motion and axial rotation on the axis

[0036] 52 fuse 31 in the fuse bracket 24 and in the multi-stage groove 193 with holes 194 of the receiver 1.

[0037] The fuse bracket 24 is fixed in the multi-stage groove 193 with holes using the fastening screws of the fuse bracket 30

[0038] 194 into the through threaded holes 195 of the receiver 1, wherein the safety catch 31 has the ability to interact with the bolt body 4, the lugs 66 of the bolt body 4 and the striker 36, as well as with the projection 230 on the end of the L-shaped plate 225 of the bracket of the safety catch 24 and the grooves 231 of the bracket of the safety catch 24. With this design solution of the safety catch 31, there are no grooves and holes through which dirt and sand can get into the receiver 1.

[0039] A distinctive feature of the proposed invention is that the bolt 63 contains a striker 36, which is inserted into a central blind cylindrical channel 85, and a firing pin 39 is fixed at the end of the striker 36 and inside the striker 36 there is a mainspring 38, which has the ability to compress and decompress in the striker 36, and rests against the stop of the mainspring 35 and is fixed by the lock of the stop of the mainspring 37 in the housing of the bolt 4 through a through groove 84. In this case, the lock of the stop of the mainspring 37 has the ability to rotate in the annular groove 87 of the housing of the bolt 4. With this solution, when the bolt 63 is inserted into the receiver 1, then through the striker 36 and the lock of the mainspring 37 there is no possibility of dirt getting into the housing of the bolt 4.

[0040] A distinctive feature of the proposed invention is that the use of a multifunctional latch creates a hinged beam system for the power unit within the stock, which serves as a stable platform. This allows for maintaining accuracy during disassembly and reassembly of the weapon, eliminating the need for sighting in.

[0041] A distinctive feature of the proposed invention is that the through window 180 for extracting the caseless ammunition 51 during firing is closed thanks to the receiver cover 21. This prevents dirt and debris from entering during weapon operation, which will increase the reliability of the weapon.

[0042] A distinctive feature of the proposed invention is that, thanks to the use of the buttstock coupling 7 and the spring of the buttstock coupling axis 10, which presses on the buttstock coupling axis 9, which, with the help of a blind groove 297, transfers this pressure to the pin of the buttstock coupling axis 12, which transfers this pressure to the buttstock coupling 7 rests against the inclined platform 284 of the buttstock coupling 7 in the inclined surface 299 of the buttstock bracket 8, thereby automatically removing the play during the operation of the buttstock 6.

On the side of the hammer 112, on the side of the part of the rod 110, there is a projection 115 with a flat platform 116. The projection 115 and the flat platform 116 are used to fix the striker 39 with the safety catch 31 on the safety cocking plate. On the other side of the hammer 112, on its end from the side of the part of the rod 110, a chamfer 117 is made. The chamfer 117 interacts with the chamfer 79 of the body of the bolt 4 for cocking the striking block 64 into the firing position; at the junction of the rod 110 and the hammer 112, a chamfer 118 is made.The chamfer 118 interacts with the chamfer 86 of the bolt body 4 during the reciprocating movement after the weapon is fired, thanks to... which increases the reliability and long-term operation of the striker 36. On the rod 110 along the centerline 119 of the striker 36, perpendicular to the side of the hammer 112, at a small distance from the hammer 112, a through groove 120 is made, which runs along the entire thickness of the rod 110. At the ends of the through groove 120, radius pads 121 are made. The through groove 120 and the radius pads 121 interact with the stop lock of the mainspring 37. On the rod 110 of the striker 36, at a small distance from the through groove 120 from above and slightly before reaching the end of the rod 110, an annular groove 122 is made, which acts as a dirt collector.

[0123] (side view). This configuration consists of: muzzle brake compensator 133, barrel 18 with a smooth bore, rifled cartridge 45, smooth cartridge 44, conical sleeve of the gun chamber 43, power block with mechanisms 134.

[0124] Fig. 2b shows a detailed view of the muzzle brake of the compensator 133 (side view). Fig. 27 shows the disassembly of the muzzle brake of the compensator.

[0125] 133 (side view). Muzzle brake compensator 133 consists of: muzzle brake compensator housing 19 and muzzle brake compensator inserts 20.

[0126] Fig. 28 shows a longitudinal section of the housing of the muzzle brake of the compensator 19. The housing of the muzzle brake of the compensator 19 is made in the form of a cylindrical part 135, turning into an increasing inclined cylindrical part 136, which turns into a decreasing inclined cylindrical part 137, which turns into a cylindrical part 138. On the side of the decreasing inclined cylindrical part 137, a threaded hole 139 is made for the thickness of the wall, and on the plane of the increasing inclined cylindrical part 136, at an angle to the center of the intersection of the longitudinal axis 140, at least one threaded hole 141 is made for the thickness of the wall of one or more. Threaded holes 139 and 141 are used to install the inserts of the muzzle brake of the compensator 20 and, together with the inserts of the muzzle brake of the compensator 20 or without them, form a channel for the gas jet 338 and gases 320, which perform work to reduce the recoil of the weapon.On the side of the cylindrical part 135, internal blind annular grooves 142 of different diameters and a section with a thread 143 for mounting the muzzle brake of the compensator 133 on the barrel 18 are made. Behind the blind annular grooves 142, a through hole 144 is made for the passage of a caseless projectile 51 through the housing of the muzzle brake of the compensator 19 beyond its limits. All elements of the housing of the muzzle brake of the compensator 19, their shapes and interaction with each other are shown in Fig. 28.

[0127] Fig. 29 shows a longitudinal section of the muzzle brake insert of the compensator 20 (side view). The muzzle brake insert of the compensator 20 is made in the form of a cylindrical part 145, which has an external thread 146 at one end, which can extend along the entire length of the cylindrical part 145, and at the other end at least one through hole 147 is made, which passes through the cross-section of the cylindrical part 145. On the side of the external thread 146, an inclined hole 148 is made at the end, passing into a through hole 149. The external thread 146 is used for installation in the housing of the muzzle brake of the compensator 19. The inclined hole 148 and the through holes 147 are used to divert the gas jet stream 338 formed by gases 320, and can have a different angle of inclination and size of the hole, which allows for precise adjustment of the recoil level of the weapon.Through holes 147 are used for screwing the muzzle brake insert of the compensator 20 into the body of the muzzle brake of the compensator 19, and also serve as an additional auxiliary channel for discharging excess gas jet 338. All elements of the muzzle brake insert of the compensator 20, their shapes and interaction with each other are shown in Fig. 29.

[0128] Fig. 30 shows a side view of barrel 18. Fig. 31 shows a fragment of barrel 18 (side view). Barrel 18 is made with a smooth internal bore 150 without rifling. The barrel 18 is made with a smooth cylindrical section 151, which transitions into a section with threads 152, which transitions into an annular groove 153, which transitions into a smooth cylindrical section 154, which transitions into a hexagonal section 155 for a key for installing the barrel 18 in the gun chamber 17. The hexagonal section 155 transitions into a cylindrical polished section 156, which transitions into an annular groove 157, which transitions into a threaded section with a left-hand stop thread 158. In this case, left-hand rifling is used in the rifled cartridge 45, which allows for self-locking of the barrel during firing and prevents the formation of a gap between the barrel 18, the rifled cartridge 45, the smooth cartridge 44 and the conical bushing of the gun chamber 43, and for right-handed shooters reduces the influence of derivation during firing.The threaded section with left-hand thrust thread 158 passes into the cylindrical polished section 159. Cylindrical polished sections 156 and 159, when installing the barrel 18 in the gun chamber 17, align the barrel 18 with the gun chamber 17, the rifled cartridge 45, the smooth cartridge 44 and the conical bushing of the gun chamber 43 in one line strictly along the longitudinal axis of the weapon, which ensures increased accuracy of the shot. In the forward portion of the barrel 18, instead of the smooth cylindrical section 151, the threaded section 152, and the annular groove 153, there may be a smooth cylindrical section 154 with one or more grooves 160, which extend at an angle relative to the axis of the barrel 161 toward the hexagonal section 155, which is used as a simplified version of the muzzle brake of the compensator 133 for the formation of a gas jet 338 for weapons of caliber 12 mm or less, which helps reduce recoil. All of the above-mentioned sections of the barrel 18 are made of varying thicknesses.All elements of the barrel 18, their shapes and interaction with each other are shown in Fig. 30 and Fig. 31.

[0129] Fig. 32 shows a side view of the rifled cartridge 45. The rifled cartridge contains a rifled sleeve 162, an internal smooth sleeve of the rifled cartridge 163 of one or more and an external smooth sleeve of the rifled cartridge 164. The rifled sleeve 162 is made of a hard alloy and refractory material. At least two left-hand grooves 165 are made in the rifled bushing 162, designed to create boost pressure and ensure axial rotation of the projectile 318. Furthermore, a threaded section with a left-hand stop thread 158 is used in the barrel 18, which allows for self-locking of the barrel during firing and prevents the formation of a gap between the barrel 18 and the rifled cartridge 45, and forms a hermetically sealed joint between the smooth cartridge 44 and the conical bushing of the gun chamber 43, thereby reducing the effect of deflection during firing for right-handed shooters. The pitch and shape of the rifling 165 depends on the ammunition 51 used.Rifled bushing 162, inner smooth bushing of rifled cartridge 163, and outer smooth bushing of rifled cartridge 164 are inserted into one another with tension, forming rifled cartridge 45. The outer surfaces of rifled bushing 162, inner smooth bushing of rifled cartridge 163, and outer smooth bushing of rifled cartridge 164 are polished to a mirror shine. This high-gloss polishing is intended to ensure minimal heat loss in the hottest area, as the polished surface behaves like a thermos, reflecting the heat flow, and the multi-layer structure of rifled cartridge 45 maintains high pressure during firing. Rifled cartridge 45 ensures high weapon reliability during the high gas temperatures produced by the combustion of propellant 317.Because the smooth cartridge 44 and the rifled cartridge 45 are separate components, when the rifling grooves 165 in the rifled bushing 162 at the initial contact point of the caseless ammunition 51 wear out and misfires occur, the rifled cartridge 45 can and should be flipped over to allow further operation of the weapon. This property of the rifled cartridge 45 allows for a two-fold increase in the service life of the rifled bushing 162. All elements of the rifled cartridge 45, their shapes, and interactions with each other are shown in Fig. 32.

[0130] Fig. 33 shows a longitudinal section of a smooth cartridge 44 (side view). The smooth cartridge 44 comprises a barrel bushing 166, an inner smooth bushing 167 of one or more and an outer smooth bushing 168. The barrel bushing 166, the inner smooth bushing 167 and the outer smooth bushing 168 are inserted into each other with tension and create a smooth cartridge 44. The barrel bushing 166 is longer than the inner smooth bushing 167 and the outer smooth bushing 168, while in the barrel bushing 166 on the outer side from the side of the protruding end of the barrel bushing 166 from the inner smooth bushing 167 a conical annular protrusion 169 is made repeating the shape of the conical annular groove 175 of the conical bushing of the gun chamber 43, while the length of the conical annular protrusion L169 is equal to L 169=0.4xD where D is the weapon caliber, 0.4 is the accepted coefficient for the optimal firing range.The conical bushing of the gun chamber 43, entering the conical annular projection 169 under the action of gases 320, covers the joint between the smooth cartridge 44 and the conical bushing of the gun chamber 43, which does not allow gases 320 to break through into this joint and increase the expansion force in the gun chamber 17, which reduces the requirements for the characteristics of the materials used in the gun chamber 17. On the outer smooth bushing 168 on the opposite side from the conical annular projection 169 of the barrel bushing 166 along the outer side of the cylindrical section 170, a rim 171 is made, intended for the correct assembly of the smooth cartridge 44 and the rifled cartridge 45. The outer surfaces of the barrel bushing 166, the inner smooth bushing 167 and the outer smooth bushing 168 are polished to Mirror-like shine. The multi-layer construction of the smooth 44 cartridge ensures high pressure is maintained during firing, while the high-gloss polishing ensures minimal heat loss in the hottest area.The polished surface acts like a thermos, reflecting heat flow. The joint between the smooth cartridge 44 and the rifled cartridge 45 distributes the difference in transverse deformations between the rifled cartridge 45 and the smooth cartridge 44 during firing, allowing for increased critical pressures during firing. All elements of the smooth cartridge 44, their shapes, and interactions with each other are shown in Fig. 33.

[0131] Fig. 34 shows a longitudinal section of the conical sleeve of the gun chamber 43. The conical sleeve of the gun chamber 43 is made with a cylindrical section 172, which passes into a smaller cylindrical section 173. Inside the conical sleeve of the gun chamber 43 there is a conical opening 174, the small base of which is located at the end of the cylindrical section 172. At the end of the small base of the conical opening 174 there is a conical annular groove 175, which interacts with the conical annular projection 169 of the smooth cartridge 44. All elements of the conical sleeve of the gun chamber 43, their shapes and interaction with each other are shown in Fig. 34.

All elements of the butt bracket 8, their shapes and interaction with each other are shown in Fig. 62 and Fig. 63.

[0159] Fig. 64 shows a longitudinal section of a multifunctional latch.

[0160] 62. Fig. 65 shows a detailed view of the multifunctional latch 62 (side view). The multifunctional latch 62 consists of: a multifunctional latch housing 23, a multifunctional latch stop 33 with a transverse blind hole 306, a multifunctional latch stop pin 56, and a stop spring 57.

[0161] Fig. 66 shows a longitudinal section of the housing of the multifunctional latch 23. The housing of the multifunctional latch 2.3 is made in the form of a rod 307, in the front part of which a flag 308 is made for a groove 272 in the stock 2. In the rod 307, on the side of the flag 308, a blind hole 309 is made, intended for the stop of the multifunctional latch 33 and the stop spring 57. In addition, in the rod 307 a longitudinal groove 310 is made for the thickness of the wall of the rod 307 for the cotter pin of the stop of the multifunctional latch 56, located mutually perpendicular to the flag 308. In this case, the stop of the multifunctional latch 33 has the ability to perform a reciprocating movement in the blind hole 309 of the housing of the multifunctional latch 23 while being in a spring-loaded state by the spring stop 57, and is fixed with a cotter pin of the stop of the multifunctional latch 56 in the transverse blind hole 306.The cotter pin of the multifunctional latch stop 56 is made in the form of a uniform rod and has the ability to perform a reciprocating movement in the longitudinal groove 310 of the housing of the multifunctional latch 23. All elements of the housing of the multifunctional latch 23, their shapes and interaction with each other, are shown in Fig. 66. Fig. 67 shows a side view of the extractor rod. 29.

[0162] Extractor rod 29 is formed as a flexible rod 311, which can be made of various materials. A magnet 312 is attached to one end of flexible rod 311.

[0163] In Fig.68, Fig.69 (Section 1-1 in Fig.71), the operation of the safety catch 31 in the safety position is shown. In the safety position, the safety catch 31 is completely closed, while the striker 36 has no possibility of movement, and the bolt body 4 has no possibility of rotation. The striker 36 is in the cocked position. When attempting to cock the weapon, the projection 220 of the safety catch 31 rests against the flat platform 116 of the projection of the striker 36, while the projection 220 of the safety catch 31 enters the groove 82, and rests against the side plane 83 of the bolt body 4 and thereby blocks the forward movement of the striker 36 and the rotation of the bolt body 4, thereby protecting against unauthorized tearing off of the striker 36 and opening of the bolt with mechanisms 60 when the weapon is dropped. Between the platform of the combat platoon 114 and the platform of the sear 253 of the trigger 28, there is a safety gap 313, which takes into account the wear of the rubbing surfaces of the striker 36 and the trigger 28.The safety gap 313 increases the service life and improves the reliability of the combined operation of the striker 36 and the safety catch 31. The safety catch 31 is recessed into the safety catch bracket 24 and does not extend beyond the outer wall of the trigger box 1, which prevents the unauthorized removal of the safety catch 31 from the safety position.

[0164] In Fig. 70, Fig. 71 (Section 1-1 in Fig. 73), the operation of the safety catch 31 in the fire position is shown. The flag 224 of the safety catch 31 in the fire position protrudes from the bracket of the safety catch 24, wherein the safety catch 31 rests against the projection 230 of the bracket of the safety catch 24, preventing the rotation of the safety catch 31 to the next position, thereby protecting against unauthorized extraction of the bolt with mechanisms 60 from the receiver 1. Moreover, in the event of the weapon falling on the side of the protruding flag 224 of the safety catch 31, the flag 224 of the safety catch 31, with the firing pin 36 cocked, automatically goes into the safety position, which increases the safety of the weapon as a whole.

[0165] The bolt with mechanisms 60 has the ability to rotate and move back and forth in the receiver 1, thereby ensuring the operation of the bolt with mechanisms 60. When the bolt with mechanisms 60 is in the extreme rear position, the locking stop 66 of the bolt body 4 rests against the projection 220 of the safety catch 31 and does not allow the bolt body 4 to exit the receiver 1. The safety catch 31 is constantly in the pressed position of the spring safety catch 53 and is fixed in the fire position from unauthorized closing during shaking due to the interaction of the projection on the end 223 of the stepped plate 219 of the safety catch 31 with the groove 231 of the bracket of the safety catch 24.

[0166] Fig. 72, Fig. 73 (Section 1-1 in Fig. 76) shows the operation of the safety 31 in the position of removing the bolt with mechanisms 60 from the weapon. The safety 31 is moved in the position of removing the bolt with mechanisms 60; to do this, it is necessary to press the safety 31 forward from the fire position until it stops, thereby removing it from the projection 230 of the bracket of the safety 31, and then turn the safety 31 to the extreme upper position. In this position, the bolt with mechanisms 60 can be freely removed and inserted into the receiver 1, while the projection 220 of the safety catch 31 is removed from the path of movement of the lugs 66 of the bolt body 4. The safety catch 31 is constantly in the pressed position of the spring safety catch 53 and is fixed in the position of removal of the bolt body 4 from unauthorized displacement due to the interaction of the projection 223 of the safety catch 31 with the groove 231 of the bracket of the safety catch 24.Due to the fact that the bracket of the safety catch 24 is fixed in the opening 194 in the groove 193 of the receiver 1, the axis of the safety catch 52 is fixed by the walls of the trigger box 1.

[0167] In Fig.74, Fig.75 (Section 1-1 in Fig.77), Fig.76 (Section 2-2 in

[0168] Fig. 77), Fig. 77 (Section 1-1 in Fig. 79) shows the operation of the bolt with mechanisms 60 at the moment of opening of the bolt 62. When opening of the bolt 62, the bolt body 4 is in the position in which the projection 70 of the bolt body 4 and the bolt lever 25 rest and interact with the screw surface 218 of the bolt guide 22. In this case, the combat lugs 66 of the bolt body 4 are installed opposite the through rectangular grooves 197 of the receiver 1, and when further retracting the bolt 63 back, they slide along the chamfers 207 of the gun chamber 17, the complex-shaped section 206 of the gun chamber 17 and the through rectangular grooves 197 of the receiver 1, which provides forced cocking of the firing block 64 when opening of the bolt 63, and when closing the shutter 63, forced closing of the shutter 63, which facilitates and speeds up the operation of the shutter 63.When opening the bolt 63, when rotating the bolt body 4 in the receiver 1, the chamfer 79 of the screw surface 78 slides along the chamfer 117 of the striker 36, cocking the striking block 64 in the bolt body 4 to the height of the projection 75 of the bolt body 4, and is fixed on the platform 80 of the bolt body 4, while the striking block 64 is maximally cocked, and the mainspring 38 is maximally compressed, and the striker 39 is in the extreme rear position inside the through cylindrical hole 95 of the guide rod of the conical sleeve of the bolt 41. This ensures full cocking of the striking block 64 with little effort at the moment of opening the bolt 63, and easy feeding of caseless ammunition 51 into the gun chamber 17, while when closing the bolt 63, the striking block 64 becomes cocked by the platform combat platoon 114 of the striker 36 onto the platform of the sear 253 of the trigger 28, while in the closed position of the bolt 63 the platform 80 of the bolt body 4 is removed from the path of operation of the striker block 64.

[0169] In Fig. 78 (Section 2-2 in Fig. 71), Fig. 79 (Section 2-2 in Fig. 73), Fig. 80 (Section 1-1 in Fig. 82), Fig. 81 (Section 2-2 in Fig. 73) and Fig. 82 (Section 1-1 in Fig. 84) the process of extracting caseless ammunition 51 is shown. During the extraction of caseless ammunition 51, the following occurs: the bolt 63 is in the extreme forward position in the weapon, while the caseless ammunition 51 rests against the rifled cartridge 45, and from the side of the primer 314, the ignition block 315 interacts with the platform 90 of the guide rod of the conical sleeve of the bolt 41, while the striker 39 of the striking block 64 can occupy two positions: position 39 A before firing, when the striking block 64 is cocked, and Position 39B during a misfire. To extract caseless ammunition 51 from the weapon, open bolt 63 and pull it to its rearmost position, leaving the caseless ammunition 51 in smooth-bore cartridge 44.Next, when the bolt 63 is in the extreme rear position, and the caseless ammunition 51 is inside the smooth cartridge 44, it is necessary to open the cover of the receiver 21 with the hand of the shooter, after which it is necessary to take the extractor rod 29 with the hand of the shooter and push its flexible rod 311 with the side with the magnet 312 through the through window 180 of the receiver 1 into the gun chamber 17 until it stops until the magnet 312 of the extractor rod 29 rests against the caseless ammunition 51, after which the extractor rod 29 with the caseless ammunition 51 magnetized to it is removed from the weapon through the through window 180 of the receiver 1. After removing the caseless ammunition 51 from the weapon, the shooter can close the cover of the receiver 21 with his hand.Due to the fact that the parts involved in the extraction of caseless ammunition 51 have simple shapes, perform simple work, and are not located in the weapon during its operation, thereby ensuring high reliability of extraction and operation of the weapon.

[0170] Fig. 83 (Section 1-1 in Fig. 4) shows the operation of the magazine catch 27. When firing the weapon, the magazine is located in the magazine well 269 of the stock 2 and is fixed by the console 261 of the magazine catch 27, wherein the magazine catch 27 is under constant pressure through the first bent end 240 of the spring of the magazine catch 48, thereby ensuring reliable fixation of the magazine 15 during the operation of the weapon. By pressing on the stop pad of the button 260 of the magazine catch 27, the magazine catch 27 rotates on the axis of the trigger and the magazine catch 49, releasing the magazine 15 from the action of the console 261 of the magazine catch 27, after which the magazine 15 can be removed from the weapon. Thanks to the separate spring of the magazine catch 48, the possibility of rigid fixation of the magazine is ensured, which ensures high reliability in the operation of the weapon.

[0172] (Section 1-1 in Fig. 4) shows the operation of the trigger 28. When the trigger 28 is pressed, the trigger 28, rotating on the axis of the trigger and magazine catch 49, with its platform, the sear 253 slides off the platform of the combat platoon 114 of the striker 36. In this position, the trigger spring 47 and the mainspring 38 are in the maximum load mode, and the compression force from the mainspring

[0173] 38 is transmitted through the stop of the mainspring 35 to the retainer of the mainspring stop 37, which, being in the annular groove 87 of the housing of the bolt 4, transmits the compression force from the mainspring 38 to the housing of the bolt 4. Under the action of the mainspring 38, the striking block 64, thanks to the released striker 36, with the conical section 124 of the striker 39 strikes the primer 314 of the caseless ammunition 51. A shot is fired.

[0174] After firing the shot, releasing the trigger 28, the trigger 28, under the action of the trigger spring 47, rises to the upper position and rests with the platform 252 of the trigger 28 against the hammer 112 of the striker 36, which does not allow the trigger 28 to take the extreme upper position, which allows you to visually determine whether the striking block 64 is cocked or not, which in turn increases the safety of the weapon. To fire the next shot, it is necessary to release the trigger 28, and then rotate the bolt 63 until it stops, while the lugs 66 of the bolt body 4 will disengage from the gun chamber 17. And the protrusion

[0175] 75 with the screw surface 78 and the chamfer 79 of the bolt body 4, the striking block 64 is moved back and the striking block 64 will occupy the extreme rear position. Next, it is necessary to move the bolt 63 back until it stops and push it forward until it stops, while the bolt 63 on its way takes the caseless ammunition 51 from the magazine 15 and feeds it into the smooth cartridge 44 with the weapon chamber 17. Next, it is necessary to turn the bolt body 4 in the reverse order until it stops, thereby locking the bolt 63 in the weapon chamber 17. In this case, the trigger 28, under the action of the trigger spring 47, rises to the extreme upper position and the sear platform 253 of the trigger 28 becomes in the path of movement of the striker 36. Then the striker 36 with its combat platoon platform 114 goes behind the sear platform 253 of the trigger 28, thereby becoming on the combat platoon. The weapon is ready for the next shot, and to continue shooting you need to press the trigger 28.Thanks to the adjusting screw of the trigger spring 46, by screwing or unscrewing in the through threaded hole 249 of the trigger guard 3, it is possible to regulate the pressure force of the trigger spring 47 pressing on the platform of the sear 253 of the trigger 28. Thanks to this, the force that the shooter must apply to the trigger 28 to fire a shot is regulated, which in turn increases the convenience and reliability of the weapon’s operation.

[0176] Fig. 87, Fig. 88, Fig. 89 and Fig. 90 show the operation of the buttstock with mechanisms 274. An attached buttstock 6 of any configuration can be installed in the threaded hole 283 of the connecting coupling of the buttstock 7, and thanks to the connecting coupling of the buttstock 7, the attached buttstock 6 folds. In this case, in the unfolded state, the attached buttstock 6 is rigidly fixed with the help of the connecting coupling of the buttstock 7, which with its groove 291 enters the projection 275 of the stock 2, thereby preventing the attached buttstock 6 from folding in the event of unauthorized lateral pressure on the attached buttstock 6.And thanks to the spring of the axis of the coupling of the buttstock 10, which presses on the axis of the coupling of the buttstock 9, which, with the help of the blind groove 297, transfers this pressure to the pin of the axis of the coupling of the buttstock 12, which transfers this pressure to the coupling of the buttstock 7 rests against the inclined platform 284 of the coupling of the buttstock 7 in the inclined surface 299 of the bracket of the buttstock 8, thereby automatically removing the play during the operation of the attached buttstock 6.

[0177] In order to fold the attached butt 6, it is necessary to press on the lower projection 287 of the coupling sleeve of the butt 7 until it stops, whereby the plate 298 of the bracket of the butt 8 will come to the level of the rectangular groove 285 of the coupling sleeve of the butt 7, then it is necessary to turn the coupling sleeve of the butt 7, whereby the radius end 300 of the butt bracket 298 interacts with the rectangular groove 285 of the coupling sleeve of the butt 7. When the inclined platform 284 of the coupling sleeve of the butt 7 becomes parallel to the inclined platform 299 of the bracket of the butt 8, then under the action of the spring of the axis of the coupling sleeve of the butt 10, the coupling sleeve of the butt 7 will rest with the inclined platform 284 against the inclined platform 299 of the bracket of the butt 8. In this case, the attached butt 6 is folded and fixed. To unfold the stock 6, it is necessary to repeat all the above described operations in reverse order.In order to assemble the buttstock, it is necessary to bring the through holes 288 and 289 of the buttstock coupling 7 to the level of the through hole 304 of the buttstock bracket 8, while in the buttstock coupling 7, in the transverse hole 290, the pin of the buttstock coupling axis 12 is installed in such a way that one part of the pin protrudes inside the through hole 289, and in the through hole 304 and the blind hole 305 of the buttstock bracket 8, the bushing of the buttstock bracket 11 is installed, in which the spring of the buttstock coupling axis 10 is also installed. Further, the axis of the buttstock coupling 9 passes through the through holes 288 and 289 of the buttstock coupling 7, the spring of the buttstock coupling axis 10 and the bushing of the buttstock bracket 11.In this case, the longitudinal groove 295 on the axis of the coupling of the buttstock 9 is located on the side of the protruding part of the pin of the axis of the coupling of the buttstock 12, which allows, using a screwdriver installed in the slot 296 of the axis of the coupling of the buttstock 9, to press on the axis of the coupling of the buttstock 9 until the protruding part of the pin of the axis of the coupling of the buttstock 12 rests against the inner wall of the groove 294 of the axis of the coupling of the buttstock 9. After which it is necessary to turn the screwdriver 180 degrees and release it, thus the protruding part of the pin of the axis of the coupling of the buttstock 12, passing the groove 294 of the axis of the coupling of the buttstock 9, will come to the level of the blind groove 297 of the axis of the coupling of the buttstock 9, where, under the action of the spring of the axis of the coupling of the buttstock 10, it will rest the axis of the coupling of the buttstock 9 with the inner wall of the blind groove 297 in pin of the buttstock coupling axis 7, which will fix the buttstock axis in the buttstock coupling 7.Next, a stock of any configuration is installed into the threaded hole 283 of the connecting sleeve of the buttstock 7.

[0178] In Fig.91 (section 2-2 in Fig.1), Fig.92 (section 3-3 in Fig.1), Fig.93 (section 1-1 in Fig.91), Fig.94 (section 2-2 in Fig.1), Fig.95 and Fig.96 (section

[0179] 1-1 in Fig. 95) the operation of the multifunctional latch 62 is shown.

[0180] The multifunctional latch 62 in the front part of the weapon is located in the through stepped cylindrical hole 270 of the stock 2 and in the through hole 192 of the receiver 1, due to which it fastens the receiver with the mechanisms 58 with the stock assembly 59. And in the rear part of the weapon, the multifunctional latch 62 is located in the through stepped cylindrical hole 270 of the stock 2, the through hole 245 of the trigger guard 3 and in the through hole 192 of the receiver 1, due to which it fastens the receiver with the mechanisms 58 with the stock assembly 59 and the trigger guard with the mechanisms 61. The multifunctional latch 62 is held in the weapon by the cotter pin of the stop of the multifunctional latch 56, which presses on the inner the wall of the groove 279 of the bed 2 and the flag 308 of the housing of the multifunctional latch 23, which rests against the outer wall of the groove 272 of the bed 2.In this case, the rod 307 of the housing of the multifunctional latch 23 on the opposite side of the flag 308 of the housing of the multifunctional latch 23 protrudes from the stock 2. In order to remove the multifunctional latch 62 from the weapon, it is necessary to press on the housing of the multifunctional latch 23 from the side of the protruding part, due to which the flag 308 of the housing of the multifunctional latch 23 will come out of the groove 272 of the stock 2, after which the multifunctional latch 62 must be turned clockwise or counterclockwise until the moment when the cotter pin of the stop of the multifunctional latch 56 comes out to the level of the groove 271 of the stock 2, where, under the action of the spring of the stop 57, the stop of the multifunctional latch 33 pushes the cotter pin of the stop of the multifunctional latch 56 out of the groove.

[0181] 279 stock 2 into groove 271, which will release the multifunctional latch 62 from engagement and allow it to be completely removed from the weapon. In order to attach the multifunctional latch 62, it is necessary to insert the rod 307 into the through stepped cylindrical hole 270 and align the cotter pin of the stop of the multifunctional latch 56 with the groove 271 on the bar of complex shape 266 of the bed 2. At the same time, we press with a finger on the spring-loaded stop of the multifunctional latch 33 with the spring of the stop 57 and recess the cotter pin of the stop of the multifunctional latch 56 along the groove 271 until the cotter pin of the stop of the multifunctional latch 56 stops in the groove 279. Then, without releasing the pressure from the stop of the multifunctional latch 33, it is necessary to turn the flag 308 by 90 degrees clockwise.The pin of the multifunctional latch stop 56 rotates in the annular groove 279 and rises to a vertical position, while the flag 308 engages the groove 272 under the action of the spring of the stop 57 and locks there, preventing the multifunctional latch 62 from rotating. The flag 308 overlaps the groove 271, thereby preventing dirt from entering the weapon.

[0182] Fig. 97 illustrates the operation of the weapon during the preliminary period. The preliminary period 316 lasts from the beginning of the ignition of the propellant 317 (solid, liquid, gaseous) until the beginning of the projectile 318 cutting into the rifling of the rifled cartridge 45.

[0183] During this period, the following processes occur: the firing pin 39 breaks the primer 314 inside the igniter block 315 and the forced flame 319 ignites the propellant 317 (solid, liquid, gaseous). Gases 320 begin to be released with high temperature and pressure. The entire process occurs in the closed space of the projectile chamber 321 for the propellant 317. The igniter block 315, under the action of gases 320, presses the guide rod of the conical sleeve of the bolt 41 to the conical sleeve of the bolt 42, which with its polished surface 101 is pressed against the polished platform 69 of the bolt body 4, thereby blocking the leakage of gases 320 into the gun chamber 17. When the gas pressure reaches the forcing pressure P о, the projectile 318 begins to cut into the rifling of the rifled cartridge 45 with its leading cylindrical part 322. At this moment, the gap 323 between the leading cylindrical part 322 of the projectile 318 and the inner surface of the smooth cartridge 44 begins to decrease and the projectile 318 begins to move forward. The value of the gap 323 depends on many values ​​and is established by calculation for each specific power of the caseless ammunition 51. Fig. 98 and Fig. 99 illustrate the operation of the weapon during the main period 325. The main period 325 lasts from the beginning of the rifling of the projectile 318 with its leading cylindrical part 322 in the rifled cartridge 45 until the complete exit of the projectile 318 from the rifled cartridge 45. During this period, the following processes occur:

[0184] 1. Obturation. With a sharp increase in pressure in the closed space of the projectile chamber 321 for the propellant 317 in the space of the smooth cartridge 43 and the rifled cartridge 45, gases 320, under high pressure, press the igniter block 315 against the guide rod of the conical sleeve of the bolt 41. Thereby blocking the gases 320 from breaking through into the through hole 88 of the housing of the bolt 4 and the through cylindrical hole 95 of the guide rod of the conical sleeve of the bolt 41. Gases 320 bypass the igniter block 315 and enter the space formed by the blind conical hole 99, the conical sleeve of the bolt 42 and the guide rod of the conical sleeve of the bolt 41. Since gases 320 act in all directions, one part of the gases 320 presses on the thick wall conical sleeve of the bolt 102, which is pressed against the polished platform 69 of the bolt body 4. This prevents the breakthrough of gases 320 into the weapon.The other part of gases 320 presses on the walls in the blind conical hole 99 of the conical sleeve of the bolt 42 and on the conical sleeve of the gun chamber 43.

[0185] 2. Rifling. Projectile 318 passes through the rifling grooves 165 of rifled cartridge 45, thereby cutting helical channels 326 on projectile 318. Projectile 318 attains the necessary rotational speed for stable flight. At the moment projectile 318 exits the rifled portion of rifled cartridge 45, gas pressure P 320 reaches its maximum value, maximum temperature T , and 70% of the projectile's muzzle velocity Vo . The combustion process of propellant 317 (solid, liquid, or gaseous) is complete.At the moment of maximum gas pressure 320, a gap 329 is formed between the conical sleeve of the bolt 42 and the conical annular projection 166 of the smooth cartridge 44, as well as a gap 330 between the conical sleeve of the weapon chamber 43 of the barrel sleeve of the smooth cartridge166 of the smooth cartridge 44 and the conical annular groove 175 of the conical sleeve of the weapon chamber 43, a gas lock 320 is formed, which does not allow the breakthrough of gases 320 into the multi-stage cylindrical hole with the threaded section 202 and the hole of smaller diameter 203 of the weapon chamber 17, thereby reducing the critical pressure on the walls of the weapon chamber 17, increasing the reliability of the weapon chamber 17 and reducing the strength requirements for the material of the weapon chamber 17. The gap formed under under the action of gases 32'0, the gap 330 in this configuration serves as a valve for relieving excess pressure of gases 320.Under the action of the pressure of gases 320, the walls of the projectile 318 are deformed and the gap 327 between the rear cylindrical part 324 of the projectile 318 and the inner surface of the rifled cartridge 45 is closed. Gases 320 in the projectile chamber 328 for the propellant 317 reforge the walls of the projectile 318. The chips formed from the creation of the helical channels 326 on the projectile 318 are blown out by gases 320 through the helical channels 326 of the projectile 318 and are partially carried out by gases 320 behind the projectile 318. If the pressure of gases 320 exceeds the permissible value, then the conical sleeve of the bolt 42 cracks, allowing gases 320 to leak out. This precautionary measure protects the weapon and the shooter. To continue using the weapon, it is necessary to replace the conical bolt sleeve 42. At elevated gas pressure 320, cracks in the smooth cartridge 44 are also possible. To continue using the weapon, it is necessary to replace the smooth cartridge 44.

[0186] Fig. 100 (where unit A is shown in Fig. 101, section Fig. 100 in Fig. 4) Fig. 101 and Fig. 102 (where section 1-1 is shown in Fig. 103, section Fig. 102 in Fig. 4). Fig. 103 illustrate the operation of the weapon during the second period 331. The second period 331 lasts from the exit of the projectile 318 from the rifled cartridge 45 until the approach of the rear part of the projectile 318 to the muzzle end of the barrel 18 or the muzzle end of the muzzle brake of the compensator 133.

[0187] During this period, the following process occurs: when the projectile 318 passes through the smooth bore of the barrel 18, gases 320 partially blow out the chips formed during the cutting of the helical channels 326 of the projectile 318. In addition, gases 320 create a gas cushion 332, thanks to a gap of size 333 formed by the rifling on the projectile 318, reducing the friction of the projectile 318 against the smooth surface of the bore 18. The size of the gap BZ 333 is equal to the height of the rifling on the projectile 318. In the second period 331, highly compressed and heated gases 320 expand and exert pressure on the projectile 318, increasing its velocity BZZZ to 98% of the initial velocity V o Projectile 318. The reduction in gas pressure 320 in the second period 331 occurs sharply according to a curvilinear relationship. Then, the muzzle brake of the compensator 133 is activated.

[0188] In the muzzle brake compensator 133, gases 320, entering the primary chamber 335 at high speed, striking the end surface of the primary chamber 335, create a reaction of the gas flow 336, with a radial swirl acting in the opposite direction of the recoil of the weapon. Further, a portion of the gases 320 burst into the threaded holes 141 of the housing of the muzzle brake compensator 19 and the through hole 149 of the insert of the muzzle brake compensator 20, and when restructuring their gas flow 337, form a gas jet 338, which, breaking out of the threaded holes 141 of the housing of the muzzle brake compensator 19 and the through holes 147 of the insert of the muzzle brake compensator 20, creates a jet thrust 339 acting in the opposite direction of the recoil of the weapon. Gas flow reactions 336, gas flow 337, gas jet 338 and jet thrust 339 reduce the recoil of the weapon.

[0189] Fig.104 (where unit A is shown in Fig.105, section of Fig.104 in Fig.4)

[0190] Fig. 105 and Fig. 106 illustrate the operation of the weapon during the period of after-effect of gases 340. The period of after-effect of gases 340 lasts from the moment when projectile 318 reaches the muzzle of barrel 18 or the muzzle of the muzzle brake of compensator 133, until the moment when gases 320 cease to act on projectile 318. During this period, the following process occurs:

[0191] Gases 320 pass through the muzzle of the barrel 18 or the muzzle of the muzzle brake of the compensator 133, outward. Projectile 318 reaches the highest initial velocity V maxapproximately twenty centimeters from the muzzle of barrel 18 or the muzzle of muzzle brake of compensator 133. The aftereffect period of gases 340 ends when the pressure of gas 320 on projectile 318 is equivalent to atmospheric pressure. After projectile 318 leaves barrel 18 or muzzle brake of compensator 133, the oncoming air flow 341 enters the helical channels 326 on projectile 318 and, passing through them at high speed, creates reaction 342, which causes additional rotation of projectile 343 around its longitudinal axis. This improves the stability of projectile 318 throughout its entire flight trajectory.When gases 320 flow out of barrel 18 or muzzle brake of compensator 133, some of gases 320 remaining in the space formed by blind conical hole 99 of conical sleeve of bolt 42 and guide rod of conical sleeve of bolt 41 will tear ignition block 315 from guide rod of conical sleeve of bolt 41 and throw it outside barrel 18 of muzzle brake of compensator 133 after projectile 318.,.

[0192] Fig. 107 (section in Fig. 4) shows the moment of recoil of the striking block 64 at the moment of firing a shot from a weapon. During the firing process, in the initial period, when the projectile 318 passes the rifled cartridge 45, the cylinders 320 exert high pressure on the primer 314, the impulse of which is transmitted to the striker 39, as a result of which the striking block 64 rolls back at high speed in the direction opposite to the movement of the projectile 318, and hits with the radius platforms 121 on the radius chamfer 132 of the retainer of the stop of the mainspring 37, while the retainer of the stop of the mainspring 37 with its flat platform 131 rests against the inner wall of the annular groove 87 of the body of the bolt 4, and the mainspring 38, being in maximum compression, has gaps between the turns, which prevents the shrinkage of the mainspring 38. The recoil impulse is partially damped by the mainspring 38.Due to this configuration, the impulse from the impact of the striking block 64 is not transmitted to the stop of the mainspring 35, which increases the reliability of the stop of the mainspring 35, and due to the radial platforms of the through groove 120 and the radial chamfer 132 of the retainer of the stop of the mainspring 37, the impulse from the impact is distributed radially over the entire plane of the radial platform 121, thereby increasing the service life of the striker 36.

[0193] Fig.68, Fig.69, Fig.70, Fig.71, Fig.72, Fig.73, Fig.74, Fig.75, Fig.76, Fig.77, Fig.78, Fig.79, Fig.80, Fig.81, Fig.82, Fig.83, Fig.84, Fig.85, Fig.86, Fig.97, Fig.98, Fig.99, Fig.100, Fig.101, Fig.102, Fig.103, Fig.104, Fig.105, Fig.106, Fig.107 disclose the operation of the proposed caseless bolt-action weapon in operation and upon firing, which will allow the weapon to:

[0194] 1. Completely eliminate recoil during firing. This is achieved through the curvilinear operation of the gases 320 during the second period 331, and the operation of the muzzle brake compensator 133 during the gas aftereffect period 340.

[0195] 2. Increase efficiency, reduce heat loss and decrease barrel heating 18. This is achieved due to the fact that the rifling force corresponds to the boost pressure level P о , in which complete combustion of the propellant 317 (solid, liquid, gaseous) occurs, as well as a set of maximum pressure P mахgases 320 and the release of the maximum temperature T, occurring in the main period 325 in the thick-walled, multi-layer, rifled cartridge 45 and the thick-walled, multi-layer, smooth cartridge 44. In the barrel with a smooth bore 18, gases 320 sharply expand and cool, the projectile 318 moves along the smooth bore of the barrel 18 in a gas cushion 332 due to the gap 333 between the channels 326 of the projectile 318 and the outer surface of the bore of the barrel 18 with minimal friction and the necessary axial rotation of the projectile 318.

[0196] 3. Reduce the length of the barrel 18. This is achieved due to the fact that the release of all thermal energy occurs in the rifled cartridge 45 and the smooth cartridge 44, the gun chamber 17 and the set of the main velocity V o projectile 318 occurs when passing through the rifled sleeve 162 of the rifled cartridge 45. Therefore, the maximum speed V mах The 318 projectile is achieved on an 18 mm barrel that is half the length of a traditional shot.

[0197] 4. Reduce the weight and dimensions of the weapon. This is achieved by increasing the operating temperature and pressure. This allows for the creation of weapons with compact dimensions, reduced weight, and high muzzle energy.

[0198] 5. Increase the durability of the 45mm threaded cartridge. This is achieved by allowing the 45mm threaded cartridge to be used on both sides of the thread, which doubles the service life of the 45mm threaded cartridge.

[0199] 6. Increase the reliability of the shutter with 60 mechanisms. This is achieved:

[0200] 6.1. due to the fact that the guide rod of the conical sleeve of the bolt 41 is fixed in the conical sleeve of the bolt 42 and is motionless at the moment of firing, while the through cylindrical hole 95 of the guide rod of the conical sleeve of the bolt 41 at the moment of firing is blocked by the ignition block 315, which makes it possible to reduce to a minimum the impulse from the action of gases 320 transmitted to the striking block 64, the stop of the mainspring 35, the retainer of the stop of the mainspring 37, the mainspring 38 and the housing of the bolt 4 in the area of ​​the annular groove 87.

[0201] 6.2. due to the fact that the stop of the mainspring 35 is separated from the stop retainer of the mainspring 37, as a result of which the stop of the mainspring 35 receives a load only from the pressure created during the compression of the mainspring 38, while the impulse from the impact of the striker 36 is not transmitted to the stop of the mainspring 35.

[0202] 6.3. due to the fact that the retainer of the mainspring stop 37 is a homogeneous solid part and works as a support beam for the striker 36, the mainspring stop 35, and the bolt body 4, and in the bolt body 4 the inner wall of the annular groove 87 has a uniform plane along the entire perimeter, which allows the retainer of the mainspring stop 37 to freely rotate 360 ​​degrees, and also reduces the level of crushing of the inner wall of the annular groove 87 of the bolt body 4 during prolonged use of the weapon.

[0203] 7. Improve the weapon's reliability and ease of operation in the safety mode. This is achieved by safety catch 31, which, when in the safety mode, is recessed into the safety catch bracket 24 and does not protrude from the weapon's overall plane, preventing accidental release from the safety mode under mechanical external influences. Moreover, in the combat mode, safety catch 31, due to the protrusion 220 on the L-shaped plate of safety catch 31, prevents the bolt and mechanisms 60 from exiting the receiver 1. In the disassembly mode, it allows the bolt and mechanisms 60 to be completely removed from the receiver 1. This makes safety catch 31 multifunctional, thereby reducing the overall number of parts in the weapon, thereby increasing the reliability and ease of operation of the weapon itself. 8. Improve the reliability and variability of the trigger mechanism and magazine catch.This is achieved due to the fact that the trigger 28 and the magazine catch 27 operate separately from each other, due to which the force of pressing the magazine catch 27 can be adjusted by changing the magazine catch spring 48 of different elasticity, and the force of pressing the trigger 28 can be adjusted by changing the trigger spring 47 of different elasticity, as well as by tightening or unscrewing the adjusting screw of the trigger spring 46 in the trigger guard 3.
