Abstract
Official abstract text for this publication.
A method for deploying a control surface from an exterior surface of a spinning projectile during flight is provided. The method including: at least partially retracting the control surface into an interior of the projectile for a portion of a full revolution of the spinning projectile and extending the control surface from the interior of the projectile for another portion of the full revolution of the spinning projectile; and maintaining the control surface in a same plane during the full revolution of the spinning projectile.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for deploying a control surface from an exterior surface of a spinning projectile during flight, the method comprising: at least partially retracting the control surface into an interior of the projectile for a portion of a full revolution of the spinning projectile and extending the control surface from the interior of the projectile for another portion of the full revolution of the spinning projectile; and maintaining the control surface in one of a same plane or parallel to the same plane during the full revolution of the spinning projectile. 2. The method of claim 1 , wherein the same plane is a horizontal plane relative to the ground. 3. The method of claim 1 , wherein the control surface is fully retracted into the interior and fully extended from the interior one time for each full revolution of the spinning projectile. 4. The method of claim 1 , wherein the control surface is fully retracted into the interior and fully extended from the interior one time for every n full revolutions of the spinning projectile, where n is an integer greater than 1. 5. The method of claim 1 , wherein the control surface comprises two control surfaces, arranged 180 degrees apart relative to the spinning projectile, wherein: each of the two control surfaces are at least partially retracted into the interior of the projectile for a portion of the full revolution of the spinning projectile and extended from the interior of the projectile for another portion of the full revolution of the spinning projectile; and each of the two control surfaces are maintained in the same plane during the full revolution of the spinning projectile. 6. The method of claim 1 , wherein the control surface further pitches around a longitudinal axis of the control surface. 7. The method of claim 1 , wherein the control surface moves from a retracted position to an extended position in translation. 8. The method of claim 1 , wherein the control surface moves from a retracted position to an extended position in rotation. 9. A projectile comprising: a body having an interior; a control surface movable between a retracted position at least partially in the interior of the projectile to an extended position extending from an exterior surface of the projectile while the projectile is spinning; means for at least partially retracting the control surface into the interior of the projectile for a portion of a full revolution of the spinning projectile and extending the control surface from the interior of the projectile for another portion of the full revolution of the spinning projectile and for maintaining the control surface in one of a same plane or parallel to the same plane during the full revolution of the spinning projectile. 10. The projectile of claim 9 , wherein the control surface comprises two control surfaces, arranged 180 degrees apart relative to the body.
