Projectile and projectile support separating device under high-speed impacts of large-mass projectile

Abstract

The invention discloses a projectile and projectile support separating device under high-speed impacts of a large-mass projectile. The projectile and projectile support separating device comprises a support, a separator, a speed reduction ring, a cushion plate, a buffering rubber pad, an inertia body and a baffle. The support is a cylinder with the two ends provided with flange plates and a boss machined on the inner wall. The support is connected with a flange plate on a gun barrel and the baffle through the flange plates. The separator, the cushion plate, the buffering rubber pad and the inertia body are arranged in the support. The end, facing the gun barrel, of the separator is in a conical shape, the other end of the separator is in a cylindrical shape, and the separator is provided with a penetrating step type center through hole. The outer circumference of the conical end of the separator is sleeved with the speed reduction ring, and the cylindrical end is positioned through a center through hole in the cushion plate. The projectile and projectile support separating device has the beneficial effects that the strong impact load can be borne, the time of the reverse impact load acting on a projectile support can be prolonged, the requirement for separation of the projectile and the projectile support under the high impact speed of the large-mass projectile is met, the additional damage of a target due to the impact of the projectile support on a target plate is effectively avoided, and repeated usage can be achieved.

Description

technical field [0001] The invention belongs to the technical field of high-speed collision laboratory test devices, and relates to a projectile and carrier separating device, in particular to a projectile and carrier separating device for a large-mass projectile launching device. Background technique [0002] Light gas cannon is one of the most commonly used technologies for dynamic high-pressure loading at present. It can launch projectiles of various shapes, and the quality, size and material of projectiles have a wide range of application. Compared with the second-level light gas gun, the first-level light gas gun is easy to operate and has a large caliber, and can load large-mass projectiles (5-7kg) to more than 400m / s, so it is often used in various scale penetration battles The study of the internal penetration mechanism. Due to the limitation of projectile shape and length-to-diameter ratio, etc., it is generally necessary to adopt sub-caliber launch technology, tha...

Problems solved by technology

The test results prove that although the bell mouth at one end of the separation block in "A Projectile and Bullet Separation Device" collapses rapidly after colliding with the bullet rest, the impulse provided by it is sufficient to meet the deceleration and separation of small-mass bullet rests.

However, the momentum of large-mass projectiles (5-7kg) has increased significantly, and a higher impulse is required to achieve deceleration and separation, that is, it is necessary to increase the time for the reverse impact load to act on the projectile holder. The bell mouth structure obviously cannot meet the requirements.
