A rotatable bionic horizontal tail with variable area

Abstract

The invention discloses a variable-area rotatable bionic horizontal tail wing, and belongs to the technical field of aircraft. The tail wing comprises a flat tail rotating mechanism, a flat tail deflection control mechanism and variable area mechanisms, wherein one end of the flat tail rotating mechanism is fixed to the center position of the tail part of a machine body, the other end of the flattail rotating mechanism is connected with the flat tail deflection control mechanism, the two groups of variable area mechanisms are symmetrically arranged on the two sides of the flat tail deflectioncontrol mechanism correspondingly, the flat tail rotating mechanism comprises a motor, a motor base and a first rotating shaft, the flat tail deflection control mechanism comprises a first steering engine, a first connecting rod, a second rotating shaft and a tail wing supporting frame, the first steering engine is fixedly mounted at the output end of the first rotating shaft, and the variable area mechanisms comprise second steering engines, second connecting rods, fixing plates, first long rods, second long rods and a plurality of feathers. The tail wing has the heading operation capacity and can integrally rotate around the axis of symmetry, after rotating at a certain angle, the lateral area is increased, and it means that the tail wing can bring a heading moment.

Description

technical field [0001] The invention belongs to the technical field of aircraft, in particular to a rotatable bionic horizontal tail with variable area. Background technique [0002] Bionic aircraft has gradually become a hot spot in recent years. The flapping wing aircraft can be extremely realistic in appearance and can have better control effects. At the same time, fixed-wing drones with higher flight efficiency are gradually adopting a series of bionic technologies. To increase the lift-to-drag ratio of the aircraft and improve the control effect, so as to meet the requirements of achieving longer flight time and adapting to more complex flight environments. At present, there are many bionic technologies applied to wings, such as bionic wings, feathered wingtips of fixed wings, etc. The empennage is also a very important lift surface and control surface, so the purpose of the present invention is to invent a method that can effectively improve lift. characteristics, dra...

AI Technical Summary

Problems solved by technology

The above control method cannot change the area of ​​the empennage, only by controlling the rudder surface to change the aerodynamic force on the empennage, thereby changing the pitch and yaw of the aircraft

Existing aircraft with a constant area have poor maneuverability when the speed of takeoff and landing is low, and the resistance will be relatively large when cruising due to the large wetted area of ​​the horizontal tail
