Abstract

Abstract

Deflagration-to-detonation transition (DDT) of composition B (TNT/RDX=40/60) with density 1.597 g/cm3 is experimentally explored by using the electrical pin and pressure sensor measurement techniques. Experimental results show that a DDT is obtained under the strong confinement condition (steel tube with inner diameter 20 mm and outer diameter 64 mm and length 500 mm), and that the detonation-induced distance is 295 ~310 mm.
