Mixed bullet belt device containing pre-set carving grooves

Abstract

The invention belongs to the field of interior ballistics transmitting, and particularly relates to a mixed bullet belt device containing pre-set carving grooves. The mixed bullet belt device containing pre-set carving grooves comprises a plastic bullet belt ring I, a metal bullet belt ring and a plastic bullet belt ring II, wherein the plastic bullet belt ring I and the plastic bullet belt ring II are arranged on two sides of the metal bullet belt ring; the pre-set carving grooves are formed in the plastic bullet belt ring I, the metal bullet belt ring and the plastic bullet belt ring II; andthe shapes of the pre-set carving grooves are the same, and are matched with a barrel and a rifle. The mixed bullet belt device containing pre-set carving grooves disclosed by the invention adopts the mixed bullet belt; after being heated, the plastic bullet belts on the two sides rapidly expand, so that the gaps between the bullet belt, the barrel and the rifle are reduced, and the sealing performance of the system is improved; and besides, the plastic bullet belts are firstly in contact and collision with the barrel instead of metal materials of which the intensity is large in an integratedmetal bullet belt, so that the collision damage on the inner wall of the barrel caused by vibration of cannonballs is reduced, finally, the performance of a launch system is improved, and the servicelife of the launch system is prolonged.

Description

technical field [0001] The invention belongs to the field of internal ballistic launching, and in particular relates to a hybrid belt device with preset grooves. Background technique [0002] During the internal ballistic launch process, there is a certain gap between the bullet belt and the barrel for the tailless projectile that needs to be loaded from the muzzle. The increase of the shell gap will directly increase the vibration amplitude of the projectile and the collision frequency between the belt and the barrel. In addition, the gap between the projectile and the gun will cause the leakage of gunpowder and gas, which will seriously affect the performance and service life of the launch system. [0003] Under the existing integral pre-grooved metal elastic belt structure, with the vibration of the projectile, the metal material on the front and rear edges of the elastic belt will directly contact and collide with the barrel, eventually causing damage to the inner wall ...

Problems solved by technology

In addition, the gap between the projectile and the gun will cause the leakage of gunpowder and gas, which will seriously affect the performance and service life of the launch system

[0003] Under the existing integral pre-grooved metal elastic belt structure, with the vibration of the projectile, the metal material on the front and rear edges of the elastic belt will directly contact and collide with the barrel, eventually causing damage to the inner wall of the barrel

In addition, the expansion effect of the metal belt material directly heated by the gunpowder gas is small, which cannot improve the contact state between the bullets and the gunpowder gas, and thus will not slow down the leakage of the gunpowder gas
