摘要
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 highspeed 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.关键词
