EFFECTS OF PRESSURE ON THE STABILITY OF COMBUSTION IN POROUS EXPLOSIVES

Abstract

Quantitative data are given on the pressure levels at which detonation occurs during combustion of pressed charges of RDX, PETN, and TNT. The test samples, in the form of rods 10 mm in diameter and of various degrees of porosity, were burned in a monometric bomb. Pressure vs time was recorded during burning. A sharp break in the curve occurs when combustion first penetrates the pores of the explosive. The phenomenon is also discussed in relation to two primary explosives, lead azide and mercury fulminate.
