Flexible trailing edge structure and design method thereof

Abstract

The invention discloses a flexible trailing edge structure and a design method thereof. The flexible trailing edge structure comprises a rear beam, a flat bent beam, a rigid triangular wingtip, a flexible skin, filling honeycombs, a first driver and a second driver, wherein the rear beam, the flexible skin and the rigid triangular wingtip define a containing space; the flat bent beam is arranged in the containing space and divides the containing space into a first space and a second space; the first driver is arranged in the first space; the second driver is arranged in the second space; and the filling honeycombs are arranged in the first space and the second space. The flexible trailing edge structure is low in weight and simple in configuration, meets the demands of continuous flexibledeformation and low mass of a trailing edge structure and therefore achieves the purpose of replacing a rigid flap and an aileron.

Description

technical field [0001] The invention relates to the technical field of wings, in particular to a flexible wing trailing edge structure and a design method for the flexible wing trailing edge structure. Background technique [0002] The traditional wing design only takes the aerodynamic efficiency under a single flight condition (cruising) as the design goal, and can only maintain high aerodynamic efficiency during cruising, and the existence of separated flaps and aileron gaps not only reduces the aerodynamic efficiency of the wing. Aerodynamic efficiency, and the sharp structure rubbing against the air in the gaps creates noise problems. [0003] The flutter models of flexible wings in the prior art all use mechanical rigid hinge transmission to realize the flexible deformation of the outer contour of the wing, but the internal mechanical structure and transmission structure greatly increase the structural weight, which are cumbersome and have low reliability. Used in wing...

Problems solved by technology

[0002] The traditional wing design only takes the aerodynamic efficiency under a single flight condition (cruising) as the design goal, and can only maintain high aerodynamic efficiency during cruising, and the existence of separated flaps and aileron gaps not only reduces the aerodynamic efficiency of the wing. Aerodynamic efficiency, and the sharp structure rubs against the air between the gaps, causing noise problems

[0003] The flexible wing flutter models in the prior art all use mechanical rigid hinge transmission to realize the flexible deformation of the outer contour of the wing, but the internal mechanical structure and transmission structure greatly increase the structural weight, which is cumbersome and has low reliability, so it is not easy to use in the aircraft. used in wing structure design
