PRELIMINARY ONE-DIMENSIONAL INVESTIGATION OF THE INITIATION OF LOW-DENSITY PETN BY HYDROGEN-OXYGEN DETONATION WAVES,

Abstract

Various aspects of the problem of initiation of a uniform layer of PETN by head-on collisions of plane hydrogenoxygen detonation waves are considered. It was found that low-density (1 gm/cc and 0.87 gm/cc) disc pressings of PETN 1.5 in. dia. x 0.15 in. thick consistently appeared to detonate when the initial pressure of the stoichiometric hydrogen-oxygen mixture was about 13 atm or more and the length of the detonation tube was approximately 4 in. Detonation of the PETN was inferred from the deformation of the steel containers which held the pressings rather than from a direct measurement of detonation velocity in the pressing. It was not possible to verify in these tests whether the detonations were of high order. (Author)
