Abstract:
A VISAR interferometer and a high-speed video camera are used to study the structure of detonation waves in bis-(2-fluoro-2,2-dinitroethyl)-formal mixtures with ethanol, whose mass concentration varied in the range of 0–35%. It is shown that the two types of instability existing in liquid explosives, which are the one-dimensional instability of the detonation front and the reaction failure wave instability on the edge of the charge, can be implemented in any combination. The reaction time of the studied mixtures are determined, and the varying nature of the dependence of the critical diameter of detonation and the reaction time on the diluents concentration is demonstrated.
Keywords:
