Title: Thermally actuated rocket motor safety system
Inventor: DOLAN CYRIL F
IPC: F02K9/38
Filed: 1985-05-01
Granted: 1989-05-02
Abstract: The thermally actuated rocket motor safety system has a fire temp. pyrotechnic sensor which ignites a gas generator which drives a piston to the left.  A firing pin strikes the primer in the transfer booster assembly.  The transfer booster assembly transmits explosive energy through window in the now open block ring to initiate charge which lies adjacent the rocket motor case. This stresses the rocket motor case by producing a stress raising notch in the case wall. Subsequent grain burning opens the case to vent the rocket motor pressure.  An inertia mass slides to the right upon acceleration due to normal rocket motor firing and locks in the rightmost position by a latch.
