ABSTRACT:
An improved arming-firing device that provides handling safety in a rocket otor. The arming-firing device provides pyrotechnic (out-of-line) and electrical (open and shortened initiator circuits) safety features wherein the arming-firing device is armed by rotating an assemblage of a mechanical rotor switch assembly, and solenoid wherein the solenoid aligns multiple cavities of the mechanical rotor with multiple prongs of a kinetic energy barrier assembly ad this action simultaneously electrically arms (closes circuits and removes shots) and mechanically enables the initiator whereupon receiving a firing signal fires and in turn ignites the ignitor of the rocket motor. The mating of the kinetic energy poppet-sleeve squib assembly's barrier prongs with the rotor cavities obviates rebounding, thus affording proper ignition. The mechanical barrier and a solenoid return spring prevents inadvertent firing from any cause.
