Abstract:
Results of experimental measurement of critical diameter $d_{\mathrm{cr}}$, of cast charges of TNT/RDX, TNT/potassium picrate, TNT/PETN, and liquid solutions of dinitrotoluene in bisnitroxyethylnitramine are presented. The data obtained are compared with the results of previous investigations of spin detonation waves in the systems under consideration. For both TNT-based cast charges and liquid mixtures, the domains were registered on the dependence of critical diameter on content in which $d_{\mathrm{cr}}$ remained invariant. These areas coincide with the range of sensitizer content in the mixtures in which spin phenomena are observed. Experimental results corroborate a previous conclusion that spin waves favor spreading of the general detonation process in cast systems and prevent detonation of liquid explosives.
