Description

Bullet holder and bullet head separating device

Technical Field

The invention relates to a weapon terminal killing test device, in particular to a bullet support and bullet head separating device.

Background

In an experiment to test the lethality of a small arms weapon, the test projectile comprised a bullet and a receptacle. The bullet holder has the function of centering and guiding the bullet in a launching tube (such as a gun barrel and a gun barrel), and simultaneously bears the pressure of a bore and radial pressure in the launching tube, so that the bullet obtains a certain speed and a good posture. The bullet holder should be separated from the bullet at the muzzle outlet, so that the bullet has better outer ballistic performance. In the simulation process of low-speed (for example, less than 300m/s) projection, the caliber and the form of the bullet launched by the launching device can be expanded by using the bullet holder, but the launching speed is low, the testing distance is short, and the bullet holder are difficult to separate only by air resistance. This allows the sabot and the warhead to act on the target simultaneously, causing severe interference with the warhead's endpoint test. In order to test the effect of the bullet on the target and avoid the influence of the bullet holder on the end point test, a device capable of separating the bullet from the bullet holder is needed, so that after the test projectile is discharged from the chamber, the bullet holder is separated from the bullet, and the end point killing test of the bullet cannot be interfered.

In the prior art, two methods are mainly used for realizing the separation of a bullet head and a bullet holder. One method is to use an additional separation device to separate the bullet head from the bullet holder, such as "Nonaerodynamic sabot strip for NSWCDD40-mm Gas Gun" which proposes a bullet holder blocker attached to the muzzle. This separation ware is inside to adopt the multilayer "aluminum plate + rubber circle + steel sheet" structure that can change, need install gun barrel and separation ware additional on fixed transmission platform during the use, and the separation ware all must be dismantled to the transmission completion at every turn, takes out the bullet and holds in the palm, then reassembles. However, the barrier structure such as aluminum plate and rubber is difficult to replace after deformation, so that the barrier is complicated to operate, inconvenient to use and high in cost. Another method is to realize pneumatic separation of the sabot and the warhead through a unique structural design of the sabot, for example, chinese patent publication CN104729364A describes a pneumatic separation sabot for a light-gas gun, which proposes a split sabot, specifically, an upper supporting petal and a lower supporting petal are buckled into a cylinder matched with a gun barrel, and the cylinder contains a gas vortex structure. In the launching process, air pressure higher than the outer wall of the bullet holder is formed in the air vortex structure, so that the bullet head and the bullet holder are separated. The separation mode needs to design a complex bullet support structure matched with a gun barrel, a bullet structure and pneumatic characteristics, and simultaneously needs higher launching speed to realize the separation of the bullet support and the bullet under the action of air resistance; in addition, a larger distance is required between the launching device and the target to achieve separation of the sabots.

Detailed Description

In order to make the technical solutions of the present invention better understood by those skilled in the art, exemplary embodiments of the present invention will be described below with reference to the accompanying schematic drawings. It is to be understood that the described embodiments are exemplary only and not limiting. Other embodiments contemplated by those skilled in the art based on the disclosed embodiments of the present invention shall fall within the scope of the present invention.

Fig. 1 is an axial sectional view of the bullet-holder bullet separating device of the present invention. The bullet support and bullet head separating device can be matched with a launching tube for launching test bullets for testing the killing force of weapons. The launch tube may be that of a firearm, or of a cannon, or of a projectile launcher of a dedicated testing device. The test projectile includes a carrier 6 and a bullet 8 bonded by a binder 7. Examples of the binder 7 include, but are not limited to, butter.

In the exemplary embodiment shown in fig. 1, the sabot-warhead separation apparatus includes a launch tube fastener 2 and a sabot separator 4. The launch tube fastener 2 is removably attached to the launch tube 1, for example, near the exit of the launch tube 1. The launch tube fastener 2 includes circumferential locating means for circumferentially securing the launch tube fastener to the launch tube 1 and axial locating means for axially securing the launch tube fastener 2 to the launch tube 1. In one example, one or more circumferential grooves are cut into the launch tube. The axial positioning means comprises a collar 3, which collar 3 engages in a circumferential groove of the launch tube, thereby blocking the movement of the launch tube fastener 2 in the axial direction of the launch tube 1. The circumferential locating means comprises a screw 9 which enters a radial hole in the launch tube fastener 2 and triggers the outer surface of the launch tube 1, thereby circumferentially securing the launch tube fastener 2 to the launch tube 1. Loosening the screw 9 changes the circumferential positioning of the firing tube fastener relative to the firing tube.

The sabot splitter 4 is detachably connected to the launch tube fastener 2. For example, the sabot splitter 4 may be connected to the launch tube fastener 2 by a threaded connection, a quick release mechanism, or a snap and mechanism. The sabot splitter 4 comprises a proximal end (i.e. the side end near the outlet of the launch tube), a distal end and a body between the proximal and distal ends. The proximal end has a proximal opening that communicates with the outlet of the launch tube. The distal end has a distal opening in which a resilient barrier 5 having a central opening is removably arranged. The body may be hollow cylindrical or other suitable shape. The sabot splitter 4 is configured to separate the sabot 8 of the test projectile ejected from the outlet of the launch tube 1 from the bullet 7, while allowing the bullet 7 to fly away from the distal opening of the sabot splitter 4 towards the target. Specifically, the diameter of the central opening of the elastic barrier 5 disposed in the distal opening of the sabot splitter 4 is smaller than the size of the sabot 8 and larger than the size of the bullet 7, so that when the sabot 8 strikes the proximal side of the elastic barrier 5, the sabot 8 is blocked within the hollow body of the sabot splitter 4, allowing the bullet 7 to fly through the distal opening of the sabot splitter 4/the central opening of the elastic barrier 5 toward the target.

The bullet that separates with the warhead can remain in the hollow main part of bullet support separator, treats to hold in the palm the separator and remove the back from the launching tube fastener with the bullet, can remove the bullet support from the hollow main part. In one example, the hollow body of the magazine separator 4 may be provided with an opening at the lower side, so that the magazine separated from the bullet drops out of the magazine separator from the opening.

Fig. 2 shows an axial cross-sectional view of the elastic stopper in the bullet-holder bullet-nose separating device of the present invention. In order to securely hold the elastic stopper 5 in the distal opening of the sabot splitter 4, the elastic stopper may comprise a step. In one example, the step of the resilient barrier is formed between a proximal (i.e., the side closer to the firing tube) large diameter portion and a distal (i.e., the side further from the firing tube) small diameter portion. The step of the elastic stopper 5 may cooperate with a step in the distal opening of the magazine separator 4 so that the elastic stopper 5 does not fall out of the distal opening of the magazine separator 4 when the magazine hits the proximal side of the elastic stopper 5 at high speed. On the other hand, the elastic stopper 5 can be removed from the distal opening of the sabot splitter 4 in the direction toward the launch tube. Elastic barriers 5 with various opening diameters can be provided for blocking different sizes of receptacles for different test projectiles.

Fig. 3 is a sectional view showing a multi-layer structure of the elastic stopper in the bullet-catch bullet separating apparatus of the present invention. In one example, the resilient barrier 5 may be a unitary structure made of a resilient material. Examples of elastomeric materials include, but are not limited to, rubber, modified rubber, nylon, silicone materials. In another example, the elastic barrier 5 may comprise a spacer in the axial direction. The gasket may be of a different material than the elastomeric barrier body. In yet another example, the resilient barrier 5 may comprise multiple layers of shims in the axial direction, such as

shims

10 and 11 shown in FIG. 3. The proximal pad 11 (i.e., the pad on which the sabot directly strikes) may be more resilient than the distal pad 10. For example, the elastic pad 10 may be made of metal, rubber, modified rubber, nylon or silicone material, and the elastic pad 11 may be made of metal, rubber, modified rubber, nylon or silicone material, so as to reduce the impact of the bullet holder. In actual use, the number of layers, the thickness and the material of the gasket can be adjusted according to parameters such as the speed, the quality and the material of the test projectile.

The test pill can be loaded into the bottom of the launching tube in two mounting modes: front-loading and rear-loading. The front loading type is that a test pellet formed by bonding a bullet holder 6 and a bullet head 8 through grease 7 is loaded from an outlet of a launching tube 1, a metal rod extends into the launching tube from a central opening of an elastic blocking piece 5, and the test pellet is pushed to the tail of the launching tube 1 to finish loading. The back loading is to press the test projectile into the bore directly from the tail of the launch tube 1 to complete the loading.

The foregoing is only an exemplary preferred embodiment of the present invention. It will be apparent to those skilled in the art that various modifications can be made without departing from the principles of the invention and these modifications are to be considered within the scope of the disclosure.
