US Patent:

44388934, Mar 27, 1984

Filed:

Aug 10, 1973

Appl. No.:

5/392715

Inventors:

Timothy B. Sands - Acton MA
Ronald R. Sinclair - Moultonboro NH

Assignee:

Sanders Associates, Inc. - Nashua NH

International Classification:

F42B 1502

US Classification:

244 321

Abstract:

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.

Appl. No.:

5/392717

Inventors:

John A. Smith - Bedford MA
Ronald R. Sinclair - Moultonboro NH

Assignee:

Sanders Associates, Inc. - Nashua NH

International Classification:

F41G 722

US Classification:

244 315

Abstract:

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.

International Classification:

F42B 1328
F42B 1502

US Classification:

244 321

Abstract:

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.
