The Experimental Aspects of Coupling Electrical Energy into a Dense Detonation Wave. Part 1
Abstract
An investigation into the effects of coupling 108KJ of electrical energy into the region behind a dense detonation front is considered. The purpose is to overdrive the detonation velocity. This is an interim report discussing the experimental considerations and arrangement for accelerating the 8.8 mm/microsecs detonation velocity of PBX9404, by injecting a 0.17 Megamp current pulse into the conductive zone of a detonating explosive. The stored, electrical energy from a variable, fast-switched storage inductor is selectively transferred into the partially-conductive region behind the detonation front, culminating in the increase of the reaction energy in the detonation process. The effects are principally of an ohmic-heating nature. Streak camera diagnostics are employed to assess the extent to which electrical coupling can be effected in comparison to the theoretically established, 20% increase in detonation velocity. The details of experimental parameters influencing such interactions and the diagnostic techniques currently employed are discussed.
