Abstract:
Aerodynamic control apparatus for creating drag on an aircraft subjected to an airstream, the control apparatus comprising:a drag flap mechanism including:at least one control surface member being pivotally mounted on the wing for coupled movement about mutually perpendicular first and second axes, the first axis being generally parallel to a roll axis of the aircraft, the second axis being generally parallel to a yaw axis of the aircraft, the at least one control member being movable between a fully feathered position presenting minimal resistance to the airstream and a fully operative position presenting maximum resistance to the airstream;a hinge plate pivotable about a hinge plate pivot axis parallel to the yaw axis;a hinge pivotally mounting the hinge plate on the control surface member; andan actuator for moving said hinge plate from a position parallel with the airstream to a position away from the aircraft centerline.
