Abstract
An arming-firing device that provides handling safety in a rocket motor. arming-firing device provides pyrotechnic (out-of-line) and electrical (open circuit) safety features wherein the arming-firing device is armed by rotating a mechanical rotor by a solenoid that aligns multiple prongs of the barrier with multiple cavities of the rotor and this action simultaneously electrically arms (closes circuits) and mechanically enables the igniter whereupon receiving a firing signal starts the rocket motor. The mating of the 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.
