ABSTRACT:
An airplane has a control device for providing a directional moment to control yaw during high angles of attack. The control device includes a chine support member carried at the forward end of the airplane forward of the fuselage. The chine support member rotates about a chine axis which is parallel or coaxial with the longitudinal axis of the airplane. A chine is mounted to the chine support member, the chine having a pair of substantially flat, thin, flight control surfaces rigidly mounted on opposite sides of the chine support member. These flight control surfaces rotate with the chine support member to control vortices formed on the chine during flight to provide directional moments. A drive motor will rotate the chine support member to control the angle of the chine. A control means including the aircraft computer controls the drive motor.
