Description

Technical Field

[0001] This invention belongs to the field of explosive loading technology and relates to a device for increasing explosive loading space, particularly to a dispensing device whose own space can be used as explosive loading space. Background Technology

[0002] The bulk detonation warhead is filled with high-energy fuel. Driven by the explosive detonation, the high-energy fuel is ejected into the air. The high-energy fuel mixes with the air to form a large-scale active cloud. After a secondary detonation by the explosive, the active cloud produces a bulk detonation, releasing a powerful shock wave. It is one of the most powerful weapons.

[0003] The commonly used explosive detonation and dispersal method at home and abroad is as follows: a dispersal device is set in the center of the bulk detonation warhead, and the dispersal device is filled with high-energy explosives. The energy generated by the explosion of the high-energy explosives drives the movement of high-energy fuel. This method is simple in structure and easy to process and assemble.

[0004] The high-energy fuel inside the bulk detonation warhead contains liquid phase materials. Therefore, the cavity in the bulk detonation warhead that contains the high-energy fuel must be airtight. Usually, a circular loading hole is opened in the end cap of the bulk detonation warhead, and the loading hole is sealed after loading is completed.

[0005] In sealing design, the most commonly used structure is the end-face axial seal. The end-face axial seal structure consists of two parts. One part has a round hole and an end-face axial sealing groove. An O-ring rubber seal is placed in the sealing groove, and then a cover plate part is installed. The O-ring rubber seal is compressed and fits tightly with both parts at the same time, achieving a sealing effect.

[0006] Because bulk detonation warheads have a central dispersal device, the charge port can only be designed on the annular surface of the warhead end cap, excluding the dispersal device. However, with the development of bulk detonation warheads and their increasing power, the required diameter of the dispersion cloud needs to be larger, leading to larger diameters of the dispersal device. Consequently, the radial dimension of the annular surface on the warhead end cap, excluding the dispersal device, needs to be smaller, necessitating a smaller diameter for the charge port. For a 300mm diameter bulk detonation warhead, the dispersal device diameter is approximately half the warhead diameter. With the charge port designed on the annular surface, and considering the space occupied by the sealing ring, the charge port diameter is significantly reduced.

[0007] To address the issue of high-energy fuel stratification under gravity, a gelling agent is added during the high-energy fuel mixing process. The resulting gelled state is viscous. This viscous high-energy fuel enters the cavity of the bulk detonation warhead through the charging tube. As the diameter of the charging orifice decreases, the diameter of the charging tube must also decrease accordingly. The viscous high-energy fuel faces too much resistance in the small-diameter charging tube and cannot flow, resulting in the inability to complete the charging process. Summary of the Invention

[0008] To address the shortcomings of existing technologies, the present invention aims to provide a dispensing device whose own space can be used as a propellant loading space. This solves the technical problem in the prior art where, due to insufficient propellant loading space within the cavity of a bulk detonation warhead, a small-diameter propellant tube must be selected, and the flow of viscous high-energy fuel is obstructed within the small-diameter propellant tube, making it difficult to load viscous high-energy fuel into the cavity of the bulk detonation warhead.

[0009] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0010] A dispensing device whose own space can be used as a propellant loading space includes a bulk detonation warhead shell, with a propellant loading port at the center of the top surface of the bulk detonation warhead shell; a lower dispensing shell is fixedly installed at the bottom of the bulk detonation warhead shell, with both its top and bottom open; an upper dispensing shell is detachably installed on the top surface of the bulk detonation warhead shell, with its top closed and bottom open; the top of the upper dispensing shell can completely cover the propellant loading port, and the bottom of the upper dispensing shell contacts the top of the lower dispensing shell; the structure formed by the upper and lower dispensing shells is a central propellant charge, the space inside the central propellant charge is an explosive charge chamber filled with high-energy explosive; the space between the central propellant charge and the bulk detonation warhead shell is a fuel charge chamber filled with high-energy fuel.

[0011] The lower throwing shell consists of, from bottom to top, an integrated lower base throwing shell and a lower connecting throwing shell. The lower base throwing shell is a hollow cylindrical structure, and the lower connecting throwing shell is a hollow frustum structure with a gradually increasing diameter from top to bottom. The upper throwing shell consists of, from top to bottom, an integrated upper throwing shell mounting flange, an upper base throwing shell, and an upper connecting throwing shell. The upper base throwing shell is a hollow cylindrical structure, and the upper connecting throwing shell is a hollow frustum structure with a gradually decreasing diameter from top to bottom.

[0012] The method of using the dispensing device, whose own space can be used as a loading space, specifically includes the following steps:

[0013] Step 1: Filling and assembling the lower disposal shell:

[0014] The downward-dispensing casing is tilted inside the body-detonation warhead casing, and then high-energy explosives are filled into the downward-dispensing casing. Once the high-energy explosives are full, the downward-dispensing casing can maintain its tilted state.

[0015] Step 2, loading high-energy fuel:

[0016] The viscous, high-energy fuel is loaded into the fuel charging chamber through the charging tube and charging port.

[0017] Step 3: Filling and assembling the upper throwing shell:

[0018] The upper-discharge casing is filled with high-energy explosives. Then, the upper-discharge casing filled with high-energy explosives is installed on the body-detonation warhead casing. As the upper-discharge casing is installed, the bottom end of the upper-discharge casing gradually comes into contact with the top end of the lower-discharge casing, and the lower-discharge casing gradually changes from an inclined state to a vertical state. After the upper-discharge casing is fixedly installed on the body-detonation warhead casing, the lower-discharge casing is in a vertical state and the lower-base disposal casing and the body-detonation warhead casing are coaxially arranged. The open bottom end of the lower-discharge casing is closed by the bottom surface of the body-detonation warhead casing, and the top end of the lower-discharge casing and the bottom end of the upper-discharge casing are in close contact.

[0019] The present invention also has the following technical features:

[0020] In step one, the angle between the central axis of the lower base ejection casing in the tilted state and the central axis of the bulk detonation warhead casing is 3°.

[0021] In step three, the section containing the hypotenuse of the axial cross-section of the upper and lower connecting throwing shells is the contact surface of the throwing body, and the section containing the top of the lower base throwing shell is the end face of the throwing body. The area of ​​the contact surface of the throwing body is 1.8 to 2.3 times the area of ​​the end face of the throwing body.

[0022] The axial sections of both the upper and lower connecting dispersive shells are right-angled trapezoids, and the angle between the hypotenuse of the axial section of both the upper and lower connecting dispersive shells and the axis of rotation of the bulk detonation warhead shell is 10°.

[0023] The top surface of the body detonation warhead casing around the explosive loading port is provided with multiple upper dispersion casing mounting holes. The upper dispersion casing mounting holes are provided with internal threads, and upper dispersion casing mounting bolts are detachably installed in the upper dispersion casing mounting holes. The upper dispersion casing mounting bolts are provided with external threads that match the internal threads.

[0024] Compared with the prior art, the present invention has the following technical effects:

[0025] The present invention provides a dispensing device whose own space can be used as a propellant loading space. The dispensing shell is divided into upper and lower halves. When loading propellant, the upper dispensing shell is removed. The space where the upper dispensing shell is located is the propellant loading space. Since the propellant loading space is large, a large-diameter propellant loading tube can be selected. The viscous high-energy fuel has less resistance in a large-diameter propellant loading tube and can flow normally, thus being able to be smoothly loaded into the inner cavity of the bulk detonation warhead.

[0034] The high-energy explosives filled in the lower and upper throwing shells 3 and 4 are conventional high-energy explosives known in the prior art.

[0035] The following are specific embodiments of the present invention. It should be noted that the present invention is not limited to the following specific embodiments. All equivalent modifications made based on the technical solutions of this application fall within the protection scope of the present invention.

[0036] Example 1:

[0037] This embodiment provides a dispensing device whose own space can be used as a loading space for explosives, such as... Figure 1As shown, the warhead includes a bulk detonation warhead shell 1, which is a hollow cylindrical structure and a rotating body, with its axis of rotation perpendicular to the ground. A charging port 2 is located at the center of the top surface of the bulk detonation warhead shell 1. A lower dispensing shell 3 is fixedly installed at the bottom of the bulk detonation warhead shell 1, with both its top and bottom open. An upper dispensing shell 4 is detachably installed on the top surface of the bulk detonation warhead shell 1, with its top closed and bottom open. The top of the upper dispensing shell 4 completely covers the charging port 2, and its bottom contacts the top of the lower dispensing shell 3. The structure formed by the upper dispensing shell 4 and the lower dispensing shell 3 is a central charging cartridge. The space inside the central charging cartridge is an explosive charging chamber filled with high-energy explosive. The space between the central charging cartridge and the bulk detonation warhead shell 1 is a fuel charging chamber 5 filled with high-energy fuel.

[0038] The lower throwing shell 3 consists of, from bottom to top, an integrated lower base throwing shell 301 and a lower connecting throwing shell 302. The lower base throwing shell 301 is a hollow cylindrical structure, and the lower connecting throwing shell 302 is a hollow frustum structure with a gradually increasing diameter from top to bottom. The upper throwing shell 4 consists of, from top to bottom, an integrated upper throwing shell mounting flange 401, an upper base throwing shell 402, and an upper connecting throwing shell 403. The upper base throwing shell 402 is a hollow cylindrical structure, and the upper connecting throwing shell 403 is a hollow frustum structure with a gradually decreasing diameter from top to bottom.

[0039] As a specific embodiment, the method of using the dispensing device whose own space can be used as a loading space specifically includes the following steps:

[0040] Step 1: Filling and assembling the lower disposal shell:

[0041] The lower ejection casing 3 is tilted and placed inside the body detonation warhead casing 1. Then, high-energy explosives are filled into the lower ejection casing 3. After the high-energy explosives are filled, the lower ejection casing 3 can maintain its tilted state.

[0042] Step 2, loading high-energy fuel:

[0043] A large-diameter charging tube is selected, and viscous high-energy fuel is loaded into the fuel charging chamber 5 through the charging tube and the charging port 2.

[0044] Step 3: Filling and assembling the upper throwing shell:

[0045] The upper throwing shell 4 is filled with high-energy explosive and the end face of the high-energy explosive is slightly compacted. Then, the upper throwing shell 4 filled with high-energy explosive is installed on the body detonation warhead shell 1. As the upper throwing shell 4 is installed, the bottom end of the upper throwing shell 4 gradually comes into contact with the top end of the lower throwing shell 3, and the lower throwing shell 3 gradually changes from an inclined state to a vertical state. Until the upper throwing shell 4 is fixedly installed on the body detonation warhead shell 1, the lower throwing shell 3 is in a vertical state and the lower base throwing shell 301 and the body detonation warhead shell 1 are coaxially arranged. The open bottom end of the lower throwing shell 3 is closed by the bottom surface of the body detonation warhead shell 1, and the top end of the lower throwing shell 3 and the bottom end of the upper throwing shell 4 are in close contact.

[0046] As a specific embodiment of this invention, in step one, the angle between the central axis of the lower base throwing shell 301 in the inclined state and the central axis of the bulk detonation warhead shell 1 is 3°.

[0047] As a specific embodiment, the axial sections of the upper connecting dispersal shell 403 and the lower connecting dispersal shell 302 are both right-angled trapezoids, and the angle between the hypotenuse of the axial section of the upper connecting dispersal shell 403 and the lower connecting dispersal shell 302 and the axis of rotation of the body detonation warhead shell 1 is 10°.

[0048] As a specific embodiment of this invention, in step three, the cross section containing the inclined side of the axial section of the upper connecting throwing shell 403 and the lower connecting throwing shell 302 is the throwing body contact surface, and the cross section containing the top of the lower base throwing shell 301 is the throwing body end face. The area of ​​the throwing body contact surface is 1.8 times the area of ​​the throwing body end face.

[0049] In one specific embodiment, a plurality of upper dispersion shell mounting holes 6 are provided on the top surface of the bulk detonation warhead shell 1 surrounding the charge port 2. Internal threads are provided within the upper dispersion shell mounting holes 6, and upper dispersion shell mounting bolts 7 are detachably installed within the upper dispersion shell mounting holes 6. External threads matching the internal threads are provided on the upper dispersion shell mounting bolts. In this embodiment, the detachable installation of the upper dispersion shell 4 on the bulk detonation warhead shell 1 is achieved through the upper dispersion shell mounting flange 401, the upper dispersion shell mounting holes 6, and the upper dispersion shell mounting bolts 7.

[0050] The working principle of the dispensing device of the present invention, whose own space can be used as a loading space, is as follows:

[0051] After the viscous high-energy fuel is introduced into the inner cavity of the bulk detonation warhead shell 1 through the charging tube, the charging space of a conventional bulk detonation warhead is located between the dispersal shell and the shell of the bulk detonation warhead shell 1. The diameter of this charging space is small. In order to allow the charging tube to enter, only a charging tube with a small diameter can be selected. However, because the viscous high-energy fuel has too much resistance in the small-diameter charging tube, it is difficult to flow, thus hindering the charging process.

[0052] This invention divides the delivery casing into upper and lower parts. During loading, the upper delivery casing 4 is removed, and the space occupied by the upper delivery casing 4 can be used as a loading space. This provides a sufficiently large loading space, allowing for the selection of a larger diameter loading tube and facilitating a smooth loading process. However, dividing the delivery casing into upper and lower halves affects the propagation of the explosion. How to eliminate the impact of the two-half delivery casing on the propagation of the explosion is a problem that needs to be solved in the next step.

[0053] First, the contact surfaces of the lower dispersing shell 3 and the upper dispersing shell 4 need to remain tightly fitted to reliably propagate the explosion. Therefore, in this invention, the lower dispersing shell 3 is initially set at an angle. After the explosive charge is loaded, when the upper dispersing shell 4 is installed, since the upper dispersing shell 4 is installed vertically, as the contact surfaces of the upper dispersing shell 4 and the lower dispersing shell 3 gradually come into contact, the angled lower dispersing shell 3 will be straightened. That is, after the lower dispersing shell 3 and the upper dispersing shell 4 are assembled, the axes of the lower dispersing shell 3 and the upper dispersing shell 4 are both vertical. After the lower dispersing shell 3 is straightened, the force of the upper dispersing shell 4 in straightening the lower dispersing shell 3 is always maintained, that is, the lower dispersing shell 3 and the upper dispersing shell 4 are always kept close together. Due to the existence of this force, the lower dispersing shell 3 and the upper dispersing shell 4 always remain tightly fitted, and the explosion can be propagated stably when the dispersing device explodes subsequently. This force is determined by the angle between the hypotenuse of the lower connecting dispensing casing 302's axial section and the axis of rotation of the warhead casing 1. If the angle between the hypotenuse of the lower connecting dispensing casing 302's axial section and the axis of rotation of the warhead casing 1 is too small, the adhesion between the lower dispensing casing 3 and the upper dispensing casing 4 is too weak, affecting the vertical propagation and explosion of the high-energy explosive. If the angle between the hypotenuse of the lower connecting dispensing casing 302's axial section and the axis of rotation of the warhead casing 1 is too large, the bending force on the lower dispensing casing 3 is too great, and the high-energy explosive inside is prone to breakage under launch overload, affecting the explosion. Finally, through experiments, it was found that when the angle between the hypotenuse of the lower connecting dispensing casing 302's axial section and the axis of rotation of the warhead casing 1 is 3°, assembling the lower dispensing casing 3 and the upper dispensing casing 4 can stably propagate the explosion and avoid the risk of the high-energy explosive breaking.

[0054] Secondly, the size of the contact surface (i.e., the contact surface of the projectile) between the lower and upper projectile casings 3 and 4 is also a factor determining the reliable propagation of the explosion. Generally, the larger the area of ​​the contact surface, the more favorable it is for the explosion. However, experiments have shown that when the contact surface area is too large, there is more viscous high-energy fuel between them. This high-energy fuel contains solid components, which isolate the contact surface between the lower and upper projectile casings 3 and 4, creating a gap that affects the propagation of the detonation. Conversely, the smaller the contact surface area, the less solid material between them, and the smaller the gap, making the explosion propagation easier. Therefore, this invention, through theoretical calculations, collective discussion with experienced personnel, and decomposition of the above problems, conducted separate experimental evaluations of each module. Ultimately, it was concluded that when the area of ​​the contact surface is 1.8 to 2.3 times the area of ​​the projectile end face, all the above problems can be avoided, the design advantages of this invention can be fully realized, the functions of this invention can be fully realized, and the problems can be effectively solved using this invention.
