SOLID ROCKET MOTOR WITH DUAL INTERRRUPTED THRUST

摘要

ABSTRACTThe invention disclosed is a solid propellant rocketmotor, capable of providing two separate propulsive impulses to amissile. The rocket motor is connected at one end to the missilebody, the other end including an exhaust nozzle. The rocket motorcomprises two stages connected by an interstate bulkhead. Thebulkhead includes a port opening which is closed by a frangiblecover which prevents the second stage from igniting during burningof the first stage, but breaks up into harmless fragments duringfiring of the second stage.
