Abstract: A solid propellant dual pulse rocket motor (10) has a pressure vessel (12) containing two pulse grains (24, 26) separated by a barrier insulator (32). An igniter assembly (36) disposed at a fore end (16) of the pressure vessel (12) selectively ignites a first pulse grain (24) from a central cavity (34). The igniter assembly (36) also ignites a second pulse grain (26) by ejecting hot combustion gases onto the fore end of the grain.
