Description

Technical Field

[0001] The present application relates to the technical field of projectiles, and in particular to a projectile launching base and an automatic launching device. Background Art

[0002] Power, mobility and protection capability are the three major performance indicators of weapon systems. With the development of future wars and future forms, improving the power of artillery has become the main means to improve the combat effectiveness of weapons. To improve the power of artillery, it is first necessary to increase the initial velocity of artillery. Therefore, trying to increase the initial velocity of artillery is one of the main trends in the development of artillery.

[0003] At present, when a gun is fired, the combustion of the propellant drives the high-temperature and high-pressure gas to drive the projectile to move in the barrel. As the speed of the projectile increases rapidly, the space behind the projectile expands rapidly, which will cause the pressure in the chamber to decrease rapidly, which will cause the initial velocity of the gun to decrease. The technical approaches to increase the initial velocity of conventional guns are: lengthening the barrel, developing new propellants, increasing the chamber volume and charge amount, etc. These technical means either require further modification of the barrel space or increase the amount of gunpowder. Although these can increase the initial velocity of the gun, in essence, these technical means only increase the total amount of gunpowder energy acting on the projectile, and do not actually improve the efficiency of the projectile in utilizing the gunpowder energy. In addition, increasing the barrel length and changing the chamber volume will affect the overall size of the gun system. The development of new high-energy propellants will be limited by the development of chemical engineering. Based on this, it is imperative to study new gun firing technologies.

[0031] The technical solution provided by this application can at least achieve the following beneficial effects:

[0032] The present application provides a projectile launching base and an automatic launching device, the projectile launching base comprises: a base, a barrel formed by transition connection of round tubes with different inner diameters, a combustible cartridge, a piston with a gunpowder chamber, a fire transmission tube and a conductive device, the combustible cartridge is arranged in the inner wall of the barrel with different inner diameters, and a projectile is placed at the end of the small-diameter combustible cartridge that is against and located at the small-diameter port of the barrel; the first end of the piston is connected to the small-diameter combustible cartridge, and the second end is clamped at the connection between the barrel and the small-diameter end, the rear fire transmission tube of the fire transmission tube is provided with a concentric double-tube section for storing gunpowder at a gap, the front fire transmission tube of the fire transmission tube is a hollow tube with one end open and the other end closed and used to store gunpowder inside the tube, gunpowder holes are distributed on the outer walls of the front fire transmission tube and the concentric double-tube section, and the gunpowder chamber is connected to the concentric double-tube section through a first gunpowder pipeline.

[0064] In other embodiments, the outer wall of the line tube 63 is coated with a heat insulation layer to prevent the line tube 63 from igniting the black powder in the rear ignition tube 52 through high temperature when the line tube 63 transmits electricity in the conductive wire 631. In other embodiments, the pipe section of the barrel 2 with a large inner diameter and the pipe section of the barrel 2 with a small inner diameter are connected in a straight line and smoothly, and when the conductive wire 631 is not connected to electricity, the band 9 is clamped at the small inner diameter end of the barrel 2. In other embodiments, the connection strength between the front piston 44 and the rear piston 45 is greater than the pressure generated after the gunpowder in the gunpowder chamber 41 is ignited; in this way, after the fixed chamber and the movable chamber are ignited, when the pressure difference between the front and rear of the piston is greater than the squeezing pressure of the band 9 and the thread strength of the rear piston 45 and the rear ignition tube 52, the piston 4 is pushed into the straight bore of the barrel 2 to move, and the fixed chamber gunpowder gas pushes the piston 4 to slow down the increase of the space behind the bullet, compresses the movable chamber gas, maintains the bullet bottom pressure, and makes the bullet bottom pressure have a platform effect. In some other embodiments, the length and size of the first gunpowder pipe 42 are consistent with those of the first gunpowder pipe 42, so that the high-temperature and high-pressure gas generated by the combustion of the ignition powder bag in the piston 4 passes through the air hole at the same time, ensuring that the black powder in the projectile 7 and the rear ignition tube 52 are ignited at the same time.

[0065] In this embodiment, after firing, the conductive wire 631 in the circuit tube 63 is connected to electricity and begins to conduct electricity to the discharge element 61 in the gunpowder chamber 41 in the piston 4. The discharge element 61 discharges instantly and ignites the gunpowder to generate a large amount of high-temperature and high-pressure gas, which transmits fire along the first gunpowder pipe 42 to the black gunpowder in the rear fire transfer tube 52, and at the same time transmits fire along the second gunpowder pipe 43 to the black gunpowder 14 in the projectile 7; the high-temperature and high-pressure gas generated after the black gunpowder is ignited passes through the gunpowder holes 8 evenly distributed on the rear fire transfer tube 52 to ignite the gunpowder in the fixed gunpowder chamber, and at the same time, the high-temperature and high-pressure gas generated after the black gunpowder is ignited passes through the gunpowder holes 8 evenly distributed on the projectile 7 to ignite the gunpowder in the mobile gunpowder chamber. At this time, pressure is established in the mobile gunpowder chamber and the fixed gunpowder chamber at the same time. The gas in the mobile gunpowder chamber pushes the projectile 7 to start moving along the small inner diameter barrel 2. When the pressure difference between the front and rear of the piston is greater than the squeezing pressure of the bullet belt 9 and the connection strength between the piston 4 and the rear fire transfer tube 52, the connection between the piston 4 and the rear fire transfer tube 52 is destroyed, such as Figure 5 As shown, the rear piston 45 is separated from the rear fire tube 52, the ammunition belt 9 squeezes into the straight bore of the barrel 2, the piston 4 enters the straight bore of the barrel 2 and moves, and the combustion body of the fixed chamber pushes the piston 4 to compress the bottom space of the projectile, slowing down the phenomenon of the pressure drop at the bottom of the projectile caused by the rapid increase of the space behind the projectile. It can be seen that the projectile launching base provided by this embodiment can keep the pressure at the bottom of the projectile stable at a certain value without rapid decrease by designing the charge of the mobile chamber and the fixed chamber, so that the pressure at the bottom of the projectile has a platform effect. In other words, by slowing down the expansion of the space behind the projectile, the pressure at the bottom of the projectile is kept stable, so that the pressure at the bottom of the projectile has a platform effect, and the initial velocity of the projectile 7 can be increased, thereby increasing the initial velocity of the artillery, so as to be used for conventional artillery ultra-high-speed firing.

[0066] It can be seen that in the technical solution provided in the embodiment of the present application, the projectile launching base includes: a base 1, a barrel 2 formed by transition connection of circular tubes with different inner diameters, a combustible cartridge 3, a piston 4 with a gunpowder chamber 41, a fire transfer tube 5 and a conductive device 6, the combustible cartridge is arranged on the inner wall of the barrel with different inner diameters, and the projectile is placed at the end of the small-diameter combustible cartridge 3 located at the small inner diameter port of the barrel 2; the first end of the piston 4 is connected to the small-diameter combustible cartridge, and the second end is clamped at the connection between the barrel and the small inner diameter end, the rear fire transfer tube 52 of the fire transfer tube 5 is provided with a concentric double-tube section for storing gunpowder in the gap, the front fire transfer tube 51 of the fire transfer tube is a hollow tube with one end open and the other end closed and used to store gunpowder in the tube, gunpowder holes are distributed on the outer walls of the front fire transfer tube 51 and the concentric double-tube section, the gunpowder chamber 41 is connected to the gap of the concentric double-tube section through the first gunpowder pipe 42, and is connected to the second gunpowder pipe 43 At the open end of the front fire transfer tube, the front fire transfer tube 51 and the rear fire transfer tube 52 are both connected to the piston 4, and the end of the rear fire transfer tube 52 away from the piston 4 is connected to the base 1. The insulating plate 62 of the conductive device 6 is arranged at the middle position in the gunpowder chamber to form the front gunpowder chamber 411 and the rear gunpowder chamber 412. The two discharge components 61 are respectively arranged in the front gunpowder chamber 411 and the rear gunpowder chamber 412 in a mutually isolated manner. The line tube 63 passes through the rear fire transfer tube and is placed in the insulating plate 62. One conductive line 631 passes through the line hole and is connected to the discharge component 61 in the front gunpowder chamber 411 to form a front gunpowder chamber loop. The other conductive line 631 passes through the line hole and is electrically connected to the discharge component 61 in the rear gunpowder chamber 412 to form a rear gunpowder chamber 412 loop. The two conductive lines 631 in the line tube 63 away from the piston are arranged in the base in a manner that the conductive lines 631 are exposed to the outside of the base, and are electrically connected to an external power source. It can be seen that the technical solution provided by the embodiment of the present application does not need to improve the original overall structure of the barrel nor increase the amount of gunpowder, but only connects the front gunpowder chamber 411 circuit or / and the front gunpowder chamber 411 circuit through the conductive wire 631. Under the discharge of the discharge element 61, the piston enters the small inner diameter of the barrel as the mobile chamber to move in the straight bore, and the combustion body of the fixed chamber composed of the barrel section with a large inner diameter pushes the piston to compress the bottom space of the projectile, thereby alleviating the phenomenon of the drop in the bottom pressure caused by the rapid increase of the space behind the projectile. It is not difficult to see that the projectile launching base designed by the present application can keep the bottom pressure of the projectile stable within the set value range without the phenomenon of rapid drop only by designing the charge of the mobile chamber and the fixed chamber, so that the bottom pressure of the projectile has a platform effect, thereby increasing the initial velocity of the gun.

[0067] In the second aspect, the embodiment of the present application also provides an automatic launch device, which includes the projectile launching base, projectile 7 and control system described in any of the above embodiments, and the control system is electrically connected to the control switch to control the connection and disconnection of the front powder chamber circuit and the rear powder chamber 412 circuit by controlling the control switch. It can be seen that under the control of the control system, the present embodiment can electrically connect the conductive wire 631 through the control switch to ignite the gunpowder in the powder chamber. It should be noted that the control switch is respectively provided with switches connecting the two conductive wires 631, and the two switches are independent of each other, that is, the control switch can simultaneously connect the circuits where the two conductive wires 631 are located, or only connect the circuit where one conductive wire 631 is located, and can also be connected to the circuits where the two conductive wires 631 are located according to the timing set by the control system. As an embodiment, the control system can set the ignition interval according to the specific internal ballistic calculation results to make the projectile speed reach the optimal, and the ignition interval should not exceed the set time, which is 2ms. The automatic launch device with controllable ignition interval of this embodiment. It can be seen that the technical solution provided in this embodiment can keep the bottom pressure of the bullet stable within the set value range without a rapid drop by designing the charging of the mobile chamber and the fixed chamber without changing the structure of the original barrel 2, so that the bottom pressure of the bullet has a platform effect, thereby increasing the initial velocity of the gun.
