Abstract

Authors have performed the research and development of a Conical Shaped Charge System (CSC) which can launch stably projectile of one gram mass with an about 10km/sec in speed supposing the debris speed in LEO. Furthermore, a CSC which can launch an one gram mass aiming at an impact velocity of 7km/s had been developed for the purpose of checking the each collision phenomenon and the difference between the CSC which can launch a projectile in the state of fusion and the gas gun (GG) which can launch a projectile in the state of a solid at the speed near 7km/s.
Although a target speed was able to be attained with CSC by last year, it was found a following jet was existed. It also became clear that there was a problem in using for a collision experiment as it is. Then, the system of removal of this following jet was devised and checked in the experiment. It was completely removed and also became clear that the subject still remained in the projectile forming. 

On the other hand, although the speed more than 10km/s can be acquired by a CSC comparatively easily, the experiment using GG and the experiment by CSC become possible comparing with the almost same speed/mass with the equipment developed this time. This is clarifying the relation of the projectile with solid and projectile with fusion, and means becoming possible to grasp correctly the influence of the structure when solid debris collides from a 5km/s level to the level more than 10km/s.

Authors have been developing the equipment for the purpose of this object and this paper described these development processes and a comparative-experiments result.
