Formation behavior of hypervelocity reactive compostite jet

Abstract

A kind of hypervelocity reactive composite liner shaped charge(HRCLSC) structure is designed by combining tungsten additional liner and reactive cooper composite liner. The formation behavior of hypervelocity reactive composite jet (HRCJ) is studied by numerical simulation method. The velocity distribution and detonation wave propagation of HRCJ are compared with that of normal reactive composite jet (NRCJ), which proves that HRCJ has better formation performance. The influence of liner structure on the formation performance of HRCJ is investigated by changing the cone angle of the composite liner and the thickness of the additional liner, the results show that the cone angle of the liner has little effect on jet head velocity while the thickness of the additional liner has great effect on jet velocity. When the thickness of the additional liner is 5mm and the cone angle of the composite liner is 60°, the effective mass utilization rate of the jet is better, and the head velocity reaches maximum.
