Critical detonation diameter of highly desensitized low-sensitivity explosive formulations

This paper studies the detonability of low-sensitivity multicomponent explosive formulations based on RDX or HMX containing 12–20% polymer binder and, if necessary, ammonium perchlorate and aluminum. An analytical dependence of the critical diameter of low-sensitivity charges on the content of the explosive component is obtained based on the theory of the critical detonation diameter of nonuniform high-density explosive charges developed earlier by the author. The effect of the particle size of the explosive component on the critical diameter is discussed. For a 5–70% content of the explosive component, satisfactory agreement with available experimental data is obtained.
