ABSTRACT:
A method and system for reducing the critical injection parameter (h/D.su) in a solid fuel ramjet (SFRJ) by using a low h/D.sub.p fuel within the recirculation region of the grain and a higher h/D.sub.p fuel for the majority of the grain to reduce the injector pressure drop, allow higher chamber pressure and higher performance and achieve flame stabilization.
