Abstract
Experimental results on the parameters of detonation process formation in phlegmatized 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 segment in the velocity range from 882 to 1 333 m/s are obtained. The results are compared with available experimental data on the length of the pre-detonation segment 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.
