A multi-pulse rocket is equipped with a thermally insulating barrier that serves as a rupture disk or a movable plug or plate separating staged propellant grains. When a rupture disk it used, the disk can be equipped with a pyrotechnic actuator to weaken the disk upon command, enabling the propellant grain on the fore side of the disk to burst the disk at a relatively low pressure when ignition of the propellant grain is needed for additional thrust. Rupturing of the disk can also be controlled by attitude maneuvering ports on the fore side of the barrie...
1. A multi-purpose rocket motor comprising: (a) a chamber having a longitudinal axis terminating at a fore end and an aft end, and comprising a nozzle at said aft end,(b) a thermally insulating barrier dividing said chamber into fore and aft segments arranged along said longitudinal axis, with a fore propellant grain in said fore segment and an aft propellant grain in said aft segment,(c) an attitude maneuvering port in said fore segment oriented to produce attitude maneuvering of said rocket motor; and(d) a guidance and control system selecting betweena...
