Abstract

Abstract

Free surface velocity histories of a film flyer driven by electrical gun at charging voltage of 18 kV were measured using bi-sensitivity VISAR. The experimental setup, testing method, and experimental results are given in this paper. Several key factors for velocity measurement are discussed. The whole testing process lasted 1.6 s, and the final velocity reached at 6.7 km/s.
