Reverse detonation driven generator for high speed loading

Abstract

The invention belongs to the technical field of super-high-speed collision loading tests, and particularly relates to a reverse detonation drive generator. According to the technical scheme, the reverse detonation drive generator used for high-speed loading comprises a combustion chamber, an ignition head, a membrane and an emission pipe; the ignition head is mounted on the side wall close to the opening end of the combustion chamber; before the test, hydrogen and oxygen are injected into the combustion chamber through an injection hole successively, after the set time, the ignition head is externally connected with a direct-current power source to generate electric sparks, combustible gas on the opening portion of the combustion chamber carries out detonation and is gradually spread to the tail of the combustion chamber, that is, the detonation wave spreading direction is from the back to the front, and when the pressure of the opening portion of the combustion chamber reaches the critical value, the membrane is broken, and high-temperature and high-pressure gas drives a shot; compared with a tail ignition manner, the reverse detonation drive generator has the beneficial effects that the effect of the detonation pressure on the shot loading time is improved, and the emission of the shot at the higher speed is achieved.

Description

technical field [0001] The invention belongs to the technical field of ultra-high-speed impact loading test, in particular to a reverse detonation drive generator. Background technique [0002] With the continuous development of aerospace technology, human activities in space are becoming more and more frequent. At the same time, the debris generated by space spacecraft is also increasing, which has brought long-term hidden dangers to the safety of spacecraft currently operating in low orbit. , have an extremely serious impact on the aerospace industry. The average speed of space debris hitting the spacecraft is about 10km / s, and the maximum speed is even above 20km / s. Therefore, the ground simulation experiment of space debris plays an indispensable role in the spacecraft protection design and effectiveness verification. In the ground simulation experiment of space debris, the ultra-high-speed projectile launched by the ultra-high-speed launch technology device is often us...
