- Abstract
- Flame spreading over the surface of igniting solid fuels and solid propellants in gaseous environments containing an oxidant component is a phenomenon of current technological importance. It occurs during the ignition transient in solid propellant rocket motors and hybrid rocket motors, and during fires in space capsules. To date, it has not been possible to establish a thorough, fundamental understanding of the process; hence empiricism has been the only guide for developing means for its control. The subject paper reports on a basic study of the phenomenon that has resulted in illumination of the underlying mechanism and led to a rational basis for the design of systems involving the control of flame spreading rates.
