Convective Burning in Isolated Solid Propellant Cracks

Abstract

The theoretical model for describing flame spreading and combustion phenomena inside an isolated solid propellant crack has been modified: (1) to solve for the subsurface temperature profile in facilitating the study of dynamic burning effect on crack cavity pressurization, (2) to incorporate the 'Dipstick' ignition criterion postulated by C. F. Price of the Naval Weapons Center, and (3) to improve the numerical treatment of the gas-dynamic boundary conditions at the opening of the propellant crack. In addition, the governing equations are nondimensionalized and a number of dimensionless parameters have been obtained.
