Auxiliary Gas Loading of Explosives and Their Sensitivity to DDT (Deflagration to Detonation Transition),

Abstract

The object of this report is to present all previously unreported work on the auxiliary gas loading experiments in the studies of the deflagration to detonation transition (DDT) in high explosives (HE). The study was directed toward methods to rate quantitatively both cast and porous HE for their susceptibility to undergoing DDT. Granular explosives studied were RDX, waxed RDX, tetryl, TNT, and Explosive D; cast HE, TNT based compositions and plastic bonded explosives (PBXs). Sensitivity of an explosive to DDT has been rated in the present apparatus by use of an auxiliary gas loader; such ratings are presented for pressed charges at 70% and 88% TMD. Additional methods of obtaining a quantitative rating are also pointed out. Work on evaluating cast charges is still preliminary, but results are sufficient to indicate that castings are, in general, much less sensitive to DDT than pressed charges. (Author)
