多级串联式超高速飞片装置实验研究

Experimental Studies on Multiple-stage Flyers

叙述了有关多级串联飞片速度的实验研究。首先做了预备实验 ,测得了2 0 0mm炸药驱动钢飞片撞击靶板时的平面范围。设计了测量多级飞片速度的实验装置 ,采用电探针方法 ,在一发实验中同时测量了三级飞片的速度。实验测得 :初级飞片速度为 4 87km/s,1mm厚次级钢飞片速度达到 7km/s ,0 .2mm厚末级钼飞片速度接近 10km/s。

This paper describes the experimental results on multiple-stage explosive/flyer system in series. Preliminary experiment gives the planeness of flyers in ø200 mm system. Using electric pin techniques, the velocities of three-stage flyers were measured. The experimental results indicate that for the first flyer of 4.87 km/s, the second steel flyer with a thickness of 1 mm can be speeded up to 7 km/s, and the third molybdenum flyer with a thickness of 0.2mm is accelerated up to about 10 km/s.
