Description
Technical Field
The invention belongs to a projectile penetration test technology, relates to a projectile support structure of a projectile firing variable caliber projectile, and particularly relates to a sub-caliber projectile support structure of a variable caliber projectile.
Background
In the research of conventional weapon penetration explosion effect, the penetration test carried out by using a ballistic gun has very wide application. As the ballistic gun is generally reformed by adopting a standard gun, the caliber is fixed, different types of projectile bodies are required to be launched by utilizing the existing ballistic gun, and most experiments adopt secondary caliber launching.
When the ballistic gun is used for carrying out penetration test, the requirements on the sub-caliber bullet holder are as follows: on one hand, the material is required to bear high overload of gunpowder gas in the chamber, so that the material is ensured not to deform; meanwhile, the shell removing device is in harmony fit with the shell body in the bore, so that the uniform stress of the shell body in the bore is ensured, and meanwhile, the shell removing device is properly matched with the inner wall of the bore, so that the bore is not leaked and scratched.
In order to achieve certain destructive power, some weapons often use a variable caliber projectile to control penetration and explosive destructive power, and the projectile has a preset penetration depth and attacks local targets at specified positions. However, when the projectile body is used for carrying out penetration test, the variable caliber property of the projectile body makes the projectile body difficult to realize launching through a ballistic gun, and a plurality of difficulties are brought to the development and protection engineering design of a weapon warhead.
Due to the characteristics of the caliber-variable projectile body structure, a secondary caliber projectile support structure capable of transmitting the caliber-variable projectile body is not seen at present.

The front centering block consists of two semicircular rings which are symmetrically arranged, and each semicircular ring is adhered to the elastomer.
The rear centering block is provided with an axial threaded through hole, and a coaxial counter bore is arranged at the orifice of the lower end surface of the threaded through hole and used for installing an inertia screw.
The rear centering block is fixedly connected with the bottom cover through a fastening screw.
The center of the lower end face of the bottom cover is provided with an axial inner hole for hoisting the assembled assembly; the lower end face of the bottom cover is symmetrically provided with threaded through holes for being connected with the rear centering block.
The elastic belt is of a circular ring structure, the outer diameter of the elastic belt is larger than that of the rear centering block, and a coaxial annular groove is formed in the middle of the outer cylindrical surface of the elastic belt.
The tail screw is integrally of a screw structure provided with external threads, and the lower end of the projectile body is provided with an internal threaded hole matched with the tail screw.
The principle of the invention is as follows: and the front centering and the rear centering are used for assembling the variable-caliber projectile body into an equal-caliber combined body capable of being launched by a projectile gun, and the normal movement of the projectile body in the bore of the ballistic gun is ensured through the mutual constraint and the adaptation of the combined body. After the gun bore is discharged, the front centering petals are separated from the projectile body under the action of pneumatic force, the rear centering is separated from the projectile body due to the fracture of the inertia screw, then the front centering and rear centering parts fly with the projectile body along respective ballistic paths, finally the projectile body is scattered in a certain area, and finally the aim of penetrating the target body according to the preset speed and gesture is achieved.
The beneficial effects of the invention are as follows: the invention solves the problem that the variable caliber projectile body is penetrated into the target body at a preset speed and in a preset gesture in penetration test, can effectively ensure the stable emission of the variable caliber projectile body, and has the characteristics of simple structure, convenient operation and good consistency.
