Problems solved by technology

[0004] However, the two recovery devices in the aforementioned prior art have complex structures, and if the velocity of the projectile is to be damped to zero, the length of the required water pipe cannot meet the needs of use in the laboratory at all.

Abstract

The invention provides an emission-recovery integrated air cannon experiment apparatus. The air cannon experiment apparatus triggers a bullet by using air expansion to do work so as to better simulate the overload environment when the bullet is blasted, which can truly reflect the overload condition of the bullet. The air cannon experiment apparatus is mainly composed of an air cannon barrel, an annular precompressed chamber, an air cannon bracing frame, a measuring bulkhead, a decompression valve gun port, a spring decompression chamber, a test engine, a fastener, a slide rail, a clamping ring, a rupture of membranes sheet, a pressure relief aperture, a solenoid valve and an air cushion cover. A certain amount of air is fed into an air cylinder by using an air compressor, and at the same time the test engine is locked by using the fastener. When pressure inside an auxiliary segment is sufficiently enough to overcome a fastening force, the test engine is launched, and the air cannon is accelerated, evenly decelerated, and even stopped, so as to achieve soft recovery by using air. The apparatus of the invention is characterized by few movable members, simple and reliable structure, easy mounting and dismantling, and rapid decompression.

Description

technical field [0001] The invention relates to the technical field of air cannon test devices, in particular to an air cannon test device integrating launch and recovery, which is suitable for simulating low-overload test systems. Background technique [0002] During the launching process of the rocket, the rocket often explodes just after it exits the muzzle. This situation has little effect on the theoretical calculation of launch overload, but in actual launch overload, it often has a greater impact on solid propellants, especially solid propellants with microcracks, so the solid propellant under launch overload environment to test. At present, live ammunition testing is a common method, but such testing will greatly waste time, financial resources, and inefficiency, especially in complex launch site environments, where it is difficult to conduct a comprehensive analysis of failed live ammunition experiments. So there is an urgent need for a rocket launch simulation te...
