Abstract
Abstract A jet flap control system for bombs, missiles and aircraft that is deployed along the trailing edge of a wing for achieving high lift at zero angle of attack. The jet flap can be utilized to provide wing lift, roll control and a small amount of altitude control without appreciatively increasing the drag.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
163 words
A control apparatus for use with an aerial missile the combination comprising: guidance control means for said aerial missile; a wing attached to said aerial missile; aperture means positioned substantially adjacent the trailing edge of said wing and extending on either side of the center line of said wing; hollow chamber means in communication with said apertures and having two rotatable substantially cylindrical tubes independently rotatable from each other; attachment means at the inner and outer ends of said cylindrical tubes for attachment of said tubes to extend substantially along the entire length of the trailing edge of said wing and adjacent thereto; control actuator means for selectively moving said cylindrical tubes through 360* in response to signals from said guidance unit; and air passage means from said missile to said hollow chamber means; whereby compressed gas from the missile is controlled by said guidance control to cause gas flow through said air passage into said hollow chamber and out through said apertures.
Claim 2
Dependent Claim
163 words
A control apparatus for use with an aerial missile the combination comprising: guidance control means for said aerial missile; a wing attached to said aerial missile; aperture means positioned substantially adjacent the trailing edge of said wing and extending on either side of the center line of said wing; hollow chamber means in communication with said apertures and having two rotatable substantially cylindrical tubes independently rotatable from each other; attachment means at the inner and outer ends of said cylindrical tubes for attachment of said tubes to extend substantially along the entire length of the trailing edge of said wing and adjacent thereto; control actuator means for selectively moving said cylindrical tubes through 360* in response to signals from said guidance unit; and air passage means from said missile to said hollow chamber means; whereby compressed gas from the missile is controlled by said guidance control to cause gas flow through said air passage into said hollow chamber and out through said apertures.
Claim 3
Dependent Claim
31 words
The apparatus of claim 1 wherein said two rotatable cylindrical tubes have apertures for providing jet outlets and said apertures are positioned symmetrically along the longitudinal axis of said cylindrical tubes.
Claim 4
Dependent Claim
26 words
The apparatus of claim 1 wherein said two rotatable cylindrical tubes are independently movable through 360* for providing positioning of said apertures at any predetermined angle.
