Shipborne transport category airplane vertical tail structure

The present invention belongs to the technical design of the aircraft, to an improved fin structure for carrier transport category aircraft. Mounting the front fin has a rudder shaft (16) in the vertical tail box (1) before the vertical tail rudder front end (15); vertical tail box (1) has an internal surface of the vertical tail rudder by a first hinge (4), the second surface of the rear vertical tail rudder hinge (5), the vertical tail rudder first rod (6), the vertical tail rudder second rod (7), the vertical tail rudder front surface of the first lever (8 ), vertical tail rudder surface prior to the second lever (9), the rocker arm cross (10), the cross rocker shaft (11), actuator means (12), the vertical tail rudder front surface of the first hinge (13) and vertical joystick-based control surface and rear surface of the vertical tail fin rudder before the front end of the second hinge control surface (14) thereof. The present invention provides a high efficiency for manipulating having a carrier transport aircraft vertical tail structure manipulation double redundancy and improve the efficiency of directional control carrier transport category airplanes and redundancy.
