Abstract
Abstract A spin stabilized circular canard control surface for attitude control of missiles. The canard control surface guides a missile along a path determined by the attitude of a space oriented spinning canard. The canard is spun free around a spherical bearing located on a boom projecting forward of the missile nose and is disposed with its spin axis pivoted about a point in the longitudinal axis of the missile. When a disturbing force causes rotation of the missile axis from the canard axis, the canard applies to the missile a restoring torque to thereby restore coincidence of the missile and canard axes.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
110 words
A stabilized ring-wing canard controlled missile comprising: A. A MISSILE WITH A LONGITUDINAL CENTERLINE AXIS AND A CENTER OF GRAVITY; B. A BOOM PROJECTING FORWARD OF ONE END OF SAID MISSILE; C. A SPIN STABILIZED RING-WING CANARD SECURED TO SAID BOOM WITH A SPHERICAL BEARING CENTERED AT A POINT IN THE CENTER AXIS OF THE MISSILE; D. THE AXIS OF THE CANARD IS DIRECTED IN THE TRAJECTORY OF THE MISSILE AND THE CANARD IS DISPOSED FOR ROTATION TO APPLY A RESTORING TORQUE TO SAID MISSILE AND RESTORE COINCIDENCE OF SAID MISSILE AND CANARD AXES WHEN A FORCE DISTURBING THE MISSILE CAUSES ROTATION OF THE MISSILE AXIS FROM THE CANARD AXIS.
Claim 2
Dependent Claim
110 words
A stabilized ring-wing canard controlled missile comprising: A. A MISSILE WITH A LONGITUDINAL CENTERLINE AXIS AND A CENTER OF GRAVITY; B. A BOOM PROJECTING FORWARD OF ONE END OF SAID MISSILE; C.
