Pendulum based power supply for projectiles

摘要

A field coil stator of an electrical generator is fixed to the fuse body of an explosive projectile within which the rotor of the generator is supported for limited rotation dampened by a pendulum to effectively induce an electrical output from the stator field coils during and after launch of the projectile from an internally rifled gun barrel. The rotor is rotationally isolated from the stator during launch by shock absorbing means to avoid defeat of the pendulum dampening action on the rotor.
