Abstract

Abstract

A velocity interferometer system for any reflector was used to measure the free surface velocity of steel flyer. The steel flyer was driven by an explosive charge(50 mm50 mm) with two different structure. In one case ,the charge is restricted with a steel tube. In the other, there is no steel tube outside the charge. Experimental results show the restricted charge can accelerate the steel flyer more efficiently. Compared with the naked charge, the restricted charge can increase the velocity of the same steel flyer (50 mm1.5 mm) by 34.8％ and the kinetic energy by 81.7％.
