Abstract
The invention discloses a combustion light gas gun driven by convergent shock wave reflection induced detonation, which comprises a driving section, a driven section, a convergence section, a gas injection device, a launching tube and a target chamber. A pipe body of the driving section is provided with a gas injection hole, one end of the gas injection hole is closed, the other end of the gas injection hole is connected with the driven section, and a diaphragm is arranged at the connection part; a pipe body of the driven section is provided with a gas injection hole; the large diameter part of the convergence section is connected with the driven section, the small diameter part of the convergence section is connected with the launching tube, and the connection part is provided with a launching tube membrane; the gas injection device is used for injecting hydrogen gas and nitrogen gas into the driving section, and injecting hydrogen gas, oxygen gas and nitrogen gas into the driven section and the convergence section; a projectile is arranged in the launching tube, and one end of the projectile is positioned in the target chamber. The light gas gun is formed by inducing detonation after the shock wave is converged and reflected after the membrane is broken, the fuel chemical energy is used for replacing gunpowder or compressed gas for driving, the operation efficiency is high, and the pollution is small; due to the absence of a piston, the structural requirements and damage are smaller and the operating time is only on the order of milliseconds.
Description
technical field [0001] The invention relates to an ultra-high-speed launch technology, in particular to a combustion light gas cannon driven by converging shock wave reflection induced detonation. Background technique [0002] The light gas gun is a launch system that uses the expansion of low-molecular-weight gas working fluid at high temperature to do work to push the projectile and obtain a very high speed. It is a general-purpose device that can launch projectiles of various shapes, and the quality, size and material of the projectile have a wide range of adaptation. It plays an irreplaceable role in the fields of aerodynamics, aerodynamics, and high-speed collisions. [0003] Traditional light gas guns mostly use solid propellant as the primary driving energy. The use of gunpowder complicates the structure and auxiliary equipment of the gas gun, which brings many problems such as safety, pollution, and cleanliness; light gas guns that use compressed gas as the driving e...
