Abstract
Projectile fuze setback generator power source apparatuses and methods of use and manufacture are disclosed. An explosive projectile contains a fuze with a setback generator and associated fuze electronics. Upon initiation of projectile launch, the setback generator produces a voltage for use by the fuze electronics during flight. The setback generator includes a magnet maintained in place within a surrounding coil by a fastener. When a projectile is fired, rapid acceleration thereof causes the fastener to break and the magnet to be displaced longitudinally within the surrounding coil, which decreases the magnetic field and induces a current in the surrounding coil. The induced current produces a voltage that is stored in a capacitor operably coupled to the setback generators which then is used to power the fuze electronics during flight.
