Problems solved by technology

[0003] The tail of a conventional aircraft is composed of a horizontal tail and a vertical tail. The horizontal tail is responsible for the maneuverability and stability of the aircraft in the longitudinal direction, and the vertical tail is responsible for the maneuverability and stability of the horizontal direction. However, for some aircraft with a V-tail layout, the V-tail is simultaneously Responsible for the maneuverability and stability of the aircraft in the longitudinal and lateral directions, it will appear that the longitudinal direction is satisfied, but the lateral direction cannot be satisfied, and vice versa, the lateral direction is satisfied but the longitudinal direction cannot be satisfied

Abstract

The invention belongs to the field of aircraft structure design, and particularly relates to an aircraft empennage structure which comprises an empennage body, a jet rotor, a hollow jet flow rotatingshaft and a driving mechanism. A cylindrical inner cavity is formed in the empennage body, first jet flow openings are symmetrically formed in two side faces of the empennage body, and two side facesof the empennage body communicate with cylindrical inner cavity. The rotating shaft is coaxially and rotationally arranged in the cylindrical inner cavity; a second jet flow opening is formed in the outer wall of the jet flow rotor, in the rotating process of the jet flow rotor, at a certain moment, the two first jet flow openings can be sealed and blocked by the outer wall of the jet flow rotor,and at the same moment, the second jet flow opening can only coincide with and be in butt joint with one first jet flow opening, and the other first jet flow opening is sealed and blocked; one end opening of the hollow jet flow rotating shaft is connected with an air source and penetrates into the jet flow rotor, and a plurality of air outlet holes are formed in the outer wall; and the driving mechanism is used for driving the jet rotor to rotate. The aircraft empennage structure is novel in structure and convenient to control, and the aerodynamic characteristics of the whole empennage structure are higher.

Description

technical field [0001] The application belongs to the field of aircraft structure design, in particular to an aircraft empennage structure. Background technique [0002] An empennage is a device mounted on the tail of an aircraft that steers and stabilizes the aircraft. The tail can be used to control the pitch, yaw and tilt of the aircraft to change its flight attitude, and it is an important part of the flight control system. [0003] The tail of a conventional aircraft is composed of a horizontal tail and a vertical tail. The horizontal tail is responsible for the maneuverability and stability of the aircraft in the longitudinal direction, and the vertical tail is responsible for the maneuverability and stability of the horizontal direction. However, for some aircraft with a V-tail layout, the V-tail is simultaneously Responsible for the maneuverability and stability of the aircraft in the longitudinal and lateral directions, it will appear that the longitudinal directio...
