DETONATION INITIATED BY HIGH PRESSURE GAS LOADING OF A SOLID EXPLOSIVE,
Abstract
The Enig-Metcalf one dimensional code has been shown to reproduce experimental trends observed in the shock initiation of solid explosives; it has consequently been used to show that a rapid gas loading of a solid explosive to the initiating pressure for its charge geometry will effect detonation. Both the deflagration to detonation experiments (pressure generated by confined burn ing of cast explosives) and air-gap sensitivity tests (pressure generated by gaseous detonation products of an explosive donor) are examples of detonation caused by gas loading. In the stan dardized gap test for propellants, the donor gas products, after travelling 5.5 inches through a steel pipe, produce a pressure of between 21 and 37 kbar in a receptor placed at the end of the pipe. This is in good agreement with the 1-D computed value of about 50 kbar. (Author)
