Guidance is provided for a spinning projectile by measuring the magnitude of the angle between the spinning projectile and a target. This information is processed in conjunction with a body rate sensor to deduce the angular rate of the line of sight between projectile and the target. A means is provided for reducing the line of sight angular rate to zero, thus ensuring that the projectile will intercept the target.

Guidance system for a projectile

An infrared target seeker for a spinning projectile which does not require any reticle motor or gimbals is provided by a solid unit including lenses, detectors and a reticle, which is etched on one of the lenses.

Control is provided to conventional gun-fired projectiles by substituting for the standard fuze thereof a device comprising a canard frame and a main housing, which threads into the fuze well of the projectile, with the canard frame being rotatable with respect to the main housing and having deflectable canards thereon for providing vernier correction on the trajectory to the projectile.

Canard control assembly for a projectile

In a projectile including a spinning main housing and a despun canard frame having deflectable canards thereon, a pair of stator windings are disposed within the main housing and a cooperating pair of rotors are arranged within the canard frame. The first stator windings and corresponding rotor generate prime power and permit control of the rotational position of the canard frame while the second stator windings and associated rotor allow control of the deflectable canards.
