High explosives reaction model and its application to booster performance
Initiation of insensitive high explosives requires a boosting system using more sensitive and usually more energetic explosives. However, problems arise if the booster material is too energetic. The initiability of some insensitive but less energetic high explosives can be enhanced by lowering the density and decreasing the grain size or by adding a sensitive component; thus these explosives can be used as booster materials. This paper presents a unified initiation and detonation reaction model and then the simulation of the development of the detonation wave in a PBX-9502 main charge using three booster explosives: low-density superfine TATB, low-density ultrafine TATB, and X-0407. The last two are found to be acceptable for booster application. 12 refs., 5 figs.
