项目摘要
A new two-stage plasma accelerator was developed for conducting the hypervelocity acceleration of microprojectiles. The accelerator consisted of a gas gun as a first stage and a plasma accelerator as the second stage. It was confirmed that the two-stage operation performed well at any timing started by the laser trigger system. It was found that the velocity of projectiles was increased in the two-stage operation and that the velocity greatly depended on the position at the beginning of acceleration. The impact rate of projectiles on a target was also markedly increased. A glass beads with 500 mum in diameter has been accelerated up to 10 km/sec. A transition from plastic to hydrodynamic regime on 5052 aluminum alloy target occurs at about 5 km/sec for submillimeter-sized glass projectiles. Relation between crater size and projectile velocity-mass was studied. Protection form the hypervelocity impact of small size projectile to space experiment free-flyer was also investigated on the basis of the dual-element meteoroid-shield structure.
研制了一种用于微弹丸超高速加速的新型两级等离子体加速器。该加速器由气体枪作为第一级和等离子体加速器作为第二级组成。经证实,在激光触发系统启动的任何时间,两阶段操作都表现良好。结果表明,在两段运行中,弹丸的速度有所增加,并且速度与加速开始时的位置有很大的关系。弹丸对目标的撞击率也显著提高。一个直径为500微米的玻璃珠被加速到10千米/秒。在5052铝合金靶上,亚毫米尺寸的玻璃弹在约5 km/s的速度下发生从塑性到流体力学的过渡。研究了弹坑大小与弹丸速度质量的关系。在双元流星体防护结构的基础上,研究了小尺寸弹丸对空间实验自由飞行器的超高速撞击防护。
