Compound control plane used on vertical takeoff and landing aircraft

Abstract

The invention relates to a compound control plane used on a vertical takeoff and landing aircraft. The compound control plane comprises a compound control plane body, the compound control plane body is divided into an upper control plane and a lower control plane, the compound control plane body is mounted at the tail end of a wing, an engine nacelle is arranged on one side of the wing, and a propeller is arranged at the tail end of the engine nacelle; the wing comprises a front wing and a rear wing, and a wing tilting mechanism is mounted at the wing root of the wing; and the engine nacelle is fixedly connected with the wing, and the engine nacelle and the wing can tilt around a tilting shaft under driving of the tilting mechanism. The compound control plane used on the vertical takeoff and landing aircraft has the advantages that hovering of the vertical takeoff and landing aircraft is achieved through adjusting of the opening quantity of the compound control plane which is mounted on the wing, the compound control plane can achieve the common multi-face functions in the level flight process, a control system is simple and practicable, the structure is simple, and the response is rapid.

Description

technical field [0001] The invention relates to a composite rudder surface for an aircraft, in particular to a composite rudder surface for a vertical take-off and landing aircraft. Background technique [0002] The development of the tilting rotorcraft began in the 1940s, and was first developed by Bell Corporation of the United States. The success of the development of the tilting rotorcraft was a leap in the history of aircraft, but its safety has been questioned since it came out. In order to improve the longitudinal stability of the tilting rotorcraft while increasing the load capacity, the plan of tilting quadrotor aircraft was proposed. The idea of ​​a tilting quadrotor aircraft was first proposed by Bell Corporation researchers in 1979. It uses two pairs of wings, and each pair of wings is equipped with a propeller on each side, which not only increases the load capacity during vertical take-off and landing, but also greatly increases the thrust during horizontal fl...

AI Technical Summary

Problems solved by technology

At present, when the tilt rotor aircraft is hovering in the air, it needs to adjust the pitch or periodically change the pitch, control the rotor speed, etc. to change the lift force, the control system and structure are complex, and the response is slow

[0003] The existing published unauthorized patent document CN 105150558 A discloses a method for integrally forming parts and the rudder surface of the aircraft and the aircraft. The main problem to be solved is that the mechanically connected composite material parts in the prior art are processed and the performance of the parts is reduced. , larger tooling, higher cost and other issues, which are different from the problems solved by the present invention
