二級輕氣炮模擬空間碎片超高速碰撞試驗(yàn)技術(shù)

摘要: 二級輕氣炮是用來模擬空間碎片超高速碰撞效應(yīng)的重要設(shè)備。文章首先介紹了目前二級輕氣炮國內(nèi)外的發(fā)展的概況；闡述了其工作原理及所使用的工作氣體和試驗(yàn)用品；然后討論了影響二級輕氣炮性能的初始注氣壓力、活塞速度、彈丸釋放壓力、活塞質(zhì)量、彈丸質(zhì)量等若干參量；最后對反映二級輕氣炮性能的重要指標(biāo)彈丸出口速度和動(dòng)態(tài)碰撞角的測試技術(shù)和方法進(jìn)行了分析。

Abstract: Two stage light gas gun is one of the important devices to simulate hypervelocity impact effect of space debris. Firstly recent development about two-stage light gas gun is reviewed. The principle of two-stage light gas gun, its driver gas and test things are expounded. And then certain parameters affecting performance of two-stage light gas gun are discussed, including initial pressure, piston velocity, burst pressure, piston mass, projectile mass, etc. As two important performance indexes of two-stage light gas gun, , the measurement technologies of projectile velocity and dynamic impact angle are presented finally.
