Abstract

The invention discloses a helicopter tail balance mechanism and a helicopter. The helicopter tail balance mechanism comprises a horizontal tail and vertical tails mounted at two ends of the horizontaltail through vertical tail connecting parts, and a tail bean rod connecting part is arranged on the upper surface of the horizontal tail. By the aid of the helicopter tail balance mechanism, interference to a tail rotor can be avoided, the tail rotor efficiency can be effectively improved, meanwhile, the mounting space of the tail rotor can be saved, and the overall flight stability of the helicopter can be improved. The invention also discloses the helicopter using the helicopter tail balance mechanism. The overall pneumatic performance and flight stability of the helicopter using the structure can be enhanced effectively.

Description

technical field [0001] The invention relates to the field of helicopters, in particular to a helicopter tail balance mechanism and the helicopter. Background technique [0002] The helicopter tail rotor is used to balance the anti-torque and to control the helicopter's heading. Its tail lift surface mainly includes a horizontal stabilizer (abbreviated as a flat tail) and a vertical stabilizer (abbreviated as a vertical stabilizer). The horizontal tail can improve the stability of the angle of attack of the helicopter, and the vertical tail can streamline the tail rotor bracket and reduce the power required by the helicopter. In the prior art, the vertical tail of the helicopter generally adopts a single vertical tail design, and the horizontal tail and the single vertical tail adopt the design of a high-mounted horizontal tail or a rear-mounted horizontal tail. This design has the disadvantages of large installation space, large interference to the tail rotor, and poor fli...
