Laser initiation of mixtures of PETN and aluminum by a deposit

Abstract

The formation of a deposit from mixtures of PETN with fine aluminum under the action of neodymium laser radiation in a free generation mode is studied. This paper also describes the efficiency of a deposit as a means to reduce the energy of laser initiation of mixtures as a function of fineness of PETN, aluminum content in initiated mixtures and deposit, mixture density, and diameter of the laser action region on the explosive. The compositions of mixtures for preparing deposits optimal in composition, which reduce the initiation energy of mixtures of PETN and aluminum down to 3.75 times, are determined. The functioning mechanism of a deposit during laser initiation of mixtures of PETN and aluminum is under discussion.
