ABSTRACT:
The device, in a first embodiment, has utility for operation on a dual pulse missile including a booster segment for launching and includes several main components, as follows: an inertial mass, a shaft with a zig zag channel, a gearless electric motor, a switch deck and blocking rotor, another blocking rotor, and a spring which provides a restoring force which acts against the inertia of the inertial mass. In a second embodiment, the device has utility for operation on a triple pulse missile including a booster segment for launching and includes several main components, as follows: two inertial masses, a shaft with a unique zig zag channel, two gearless electric motors, two switch decks with blocking rotors, two springs which provide restorative forces which act against the inertia of the inertia masses. In each of the embodiments, the blocking rotors have notches which interface with the associated inertial mass or masses and lock the rotors against rotative movement unless the inertial masses are in the proper positions.
