Initiation Mechanisms of Solid Rocket Propellant Detonation

Abstract

The mechanisms which may lead to detonation initiation in solid rocket propellants due to accidentally applied low amplitude stimuli are studied. In particular, the effects of low speed impact are studied. A two- dimensional Lagrangian computer code is used to study the detailed hydrodynamic (or elastic-plastic) and thermodynamic behavior of propellant materials under impact conditions. It was found that only moderate temperature increases are generated in unconfined impact of a cylindrical material billet upon a rigid surface. When a second boundary is introduced, i.e., the material is at rest on a rigid base and is impacted by a rigid plate, the temperatures developed under certain conditions exceed the values achieved in unconfined impact by more than a factor of two.
