O propagacji frontu fali bocznego rozprężenia gazowych produktów detonacji w ładunku kumulacyjnym
The propagation problem has been solved in closed form of the lateral expansion wave front of gaseous detonation-products (GDP) in a plane hollowed charge. The solution has been constructed on the strength of the A. A. Ilyushin's theory of plane sections. The analytical formulae have been derived that bind the GDP lateral-expansion wave front to the coordinate defining the position of the diaphragm. The effect has been examined in detail of the GDP polytropic exponent upon the propagation velocity of the GDP lateral-expansion wave front. From the results obtained interesting conclusions can be drawn that can be made use of when optimizing the desing of the hollowed charges.
