  • Homing projectile
    Patent number: 4013245
    Abstract: An optical guidance system for a spin-stabilized autorotative projectile ing a target radiation detector, a detector cooling means, a fixed-coil electromagnet and a tuned-frequency steering vane. During projectile flight the detector temperature is reduced for increasing the sensitivity of the detector to radiation. When target radiation is detected, a signal is generated that is representative of target deviation from the flight path of the projectile. This signal sets up a periodic oscillation in an electromagnet for generating an electromagnetic force which, periodically and in phase with the oscillation, projects a steering vane into the air stream, creating a lift on the projectile to steer it to a target.
