摘　　要：在二级轻气炮上利用阻抗梯度飞片的准等熵压缩特性开展了超高速发射实验研究。通过非汇聚型超高速发射装置将25mm直径的铝合金飞片加速至11km/s以上,汇聚型超高速发射装置能够将10mm直径的钛合金飞片加速至15km/s以上,三级炮超高速发射技术为开展空间碎片防护研究提供了有力的技术支撑。A study on hypervelocity launcher techniques was carried out on the two-stage light-gas gun with quasi-isentropic compression＇of the flier-plate material with graded impedance. A 25-millimeter diameter aluminum alloy projectile was accelerated over 11 km/s using the hypervelocity launcher,and a 10-millimeter diameter titanium alloy projectile was accelerated over 15 km/s using the enhanced hypervelocity launcher. The hypervelocity launcher techniques using a three-stage gas gun was suitable for researches on the hypervelocity impact effect of spacecrafts.
