ABSTRACT:
A power relay/safing device for a fuze in a free-fall munition having an electronic circuit coupled to the fuze and to a primary power source and to a turbine generator backup power supply. At the time of munition release, an electric current is sent to the fuze from the primary power supply. If a portion of this electric current is not received at the electronic circuit, the circuit determines if various safety features have been satisfied and relays a second electric current from the turbine generator backup power supply to the fuze. The turbine generator backup power supply is activated by a lanyard at the time the munition is released.
