Abstract

Abstract

In this study we performed experiment on JBO-9021, a new kind of high insensitive explosive, in which the mass fractions of TATB, HMX and binder are 80%, 15% and 5%, respectively, under strong shock and achieved its particle velocity histories using laser interferometry and a high-speed scanning camera. We derived the initial shock pressures at different positions in the wedge-shaped test explosive from the particle velocity histories that were measured by laser interferometry and the Hugoniot curve of the unreacted JBO-9021 explosive. According to the run distance to detonation obtained by a streak camera and the locations of the pins, we investigated the Pop relationship of this high insensitive explosive as a function of the initial shock pressure and the run distance to detonation, and demonstrated that JBO-9021's shock initiation performance is superior to that of the TATB based explosive PBX9502 and the HMX based explosive PBX9501.
