Abstract : A spherical solid rocket motor for delivering boost-sustain, thrust-time performance and having a fuel grain with eight slots, at the forward end of the fuel grain, and eight star point segments forming regressive burning surface configurations is described. The fuel grain also has eight segments, with parallel sides, positioned between the star point segments to provide a large burning surface for boost and a sharp transition from boost to sustain operation.
