Abstract
The invention discloses a composite ignition type combustion light gas gun. The composite ignition type combustion light gas gun comprises a drive section, a driven section, a convergence section, anemitting tube and an ignition control system, wherein one end of the drive section is sealed, and the other end of the drive section is connected to the driven section, and a joint is clamped with a diaphragm; the tube body of the driven section is equipped with a pressure sensor; the front end of the convergence section is connected to the driven section, the rear end of the convergence section is connected to the emitting tube, and the joint of the rear end and the emitting tube is clamped with a diaphragm, and an igniter is mounted on a tube body; a shot is placed on a position, close to the diaphragm, in the emitting tube; and the ignition control system comprises a pressure sensor, a charge amplifier, a digital delay pulse generator. The light gas gun utilizes a composite ignition form, adopts mutual action between detonation waves induced by convergence shock wave reflection and detonation waves forcibly detonated by the igniter to generate intense shock waves, then, the intenseshock waves chase after the shot and are reflected, so that shot-bottom pressure is instantaneously increased, and a gas gun system with higher operation efficiency is developed with a lower price.
Description
technical field [0001] The invention relates to an ultra-high-speed launching light gas gun, in particular to a composite ignition type combustion light gas gun. Background technique [0002] Since the birth of the first light gas cannon, it has become an effective research tool in the fields of aerospace, weaponry and planetary science. Light gas gun is a dynamic high-pressure loading device developed on the basis of traditional artillery firing technology. It relies on the sudden expansion of light gas under high temperature and high pressure to do work on the projectile to achieve a higher firing speed. In recent years, with the continuous expansion of its application fields and the complexity of the model structure, it is required that this ultra-high-speed launch system can have better internal ballistic performance in a wider launch range at a lower cost. [0003] The most widely used at present is the secondary light gas gun. Traditional two-stage light gas guns use...
