Sensitivity of Explosives 6. Transition from Slow Burning to Detonation: Pressure and Velocity Measurements
Abstract
Cast confined charges of diethylnitramine dinitrate (DINA) were electrically initiated by Nichrome igniters. As slow burning accelerated toward detonation, pressure in the region around the igniter and propagation velocities over three adjacent intervals along the charge were measured. Preliminary pressure measurements on TNT and pentolite were also made. The pattern of velocity Increase in DINA is similar to that previously determined for pentolite. The pressure in the region of initiation is approximately exponential in time. The results are given in tabular and graphic form. Their relevance to the understanding of shock formation is briefly discussed.
