Ablation combustion of secondary powder explosives

The explosive transformation in a passive charge initiated by an air shock wave was studied using synchrotron diagnostics of density. It was found that in the passive charge, a compression wave capable of forming effective hot spots does not arise and classical initiation conditions do not occur. The development of the reaction can be attributed to the ablation combustion observed in studies of the initiation of secondary powder explosives by a spark and gaseous detonation.
