Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
103 words
A system for extending and retracting folding wings on rockets comprising: a base means secured to the outer surface of a rocket, a movable control surface attached to the base and rotatable through an arc of at least 90''; means for rotating the control surface including a sleeve slidably mounted in the base and having means to prevent the relative rotation thereof, and a cam surface located therein and cam follower means extending from the control surface for riding on said cam; and means for actuating said sleeve including a piston means operatively connected to the sleeve and means for driving the piston.
