Abstract:

A mechanism for an electrostatic discharge ESD initiation of a solid rocket motor is presented, based largely on discussions at a recent workshop focussed on ESD ignition of composite propellants. Electrical property measurements and breakdown phenomena have enjoyed most attention to data and did at the meeting as well. Here overviews of the formal workshop presentations are given, but the main emphasis is to convey the flow of the discussions, which included proposals on new ignition experiments now required, as well as preliminary thoughts on formulation of an ignition model. Based on the informal discussions, a recently proposed, detailed physical mechanism for ESD ignition is modified somewhat to be more consistent with experimental observations. Keywords Electrostatic discharge ignition, Propellants, Composite propellants, Solid propellants, Ignition.
