Abstract

A course correcting fuze for use in artillery warheads or other military projectiles. Mechanisms are provided whereby air brake fins and spin control fins can be deployed and retracted under computer control during projectile flight to improve targeting accuracy. Power is supplied by an innovative fuel cell module that allows for long term storage of the fuze, rapid activated during launch of the artillery shell, and sufficient power for use by the electronics and actuator motors during operation.
