Combustion, Explosion, and Shock Waves Aims and scope

Abstract

Experimental results on the parameters of detonation process formation in plastic-bonded HMX as functions of the velocity and size of spherical impactors are reported. Data on the threshold velocity of the impactor resulting in detonation initiation and on the length of the pre-detonation region in the velocity range from 882 to 1333 m/s are obtained. The results are compared with available experimental data on the length of the pre-detonation region for plane shock waves. The radio interferometry method of registration of the evolution of the explosion process initiated by the impactor is demonstrated to be fairly informative.
