Abstract
Abstract An ordnance fuze system includes a source of D.C. voltages and an encoder located on an ordnance delivery vehicle, such as an aircraft, and a magnetic transducer, decoder, and arming and fuzing circuit located on an ordnance device, such as a bomb. A ternary voltage code is encoded on the aircraft to select the delivery mode, arming time, and fuze options of the bomb. The coded signal is transferred to the bomb at aircraft-bomb separation via the transducer and decoded in the decoder, which includes a plurality of SCR''s and switch actuators, to initiate the arming and fuzing circuit which includes a plurality of fuze sensors, energy storage devices, switches, and an arming motor. The encoder includes a mechanically initiated ripple option.
