Determination of Parameters of Detonation Waves in PETN and HMX Single Crystals

摘要

Detonation parameters in PETN and HMX single crystals are experimentally studied. The state parameters at the Chapman-Jouguet point and the parameters of the Neumann spike and chemical reaction zone are obtained. The duration and width of the chemical reaction zone in single crystals are demonstrated to be appreciably greater than in pressed heterogeneous explosives.
