Wing with self-adaptive variable camber trailing edge

Abstract

The invention discloses a wing with a self-adaptive variable camber trailing edge. The wing comprises a main wing, a rear beam and a variable camber trailing edge section, wherein the variable camber trailing edge section is connected with the main wing through the rear beam; the variable camber trailing edge section comprises an upper surface skin and a lower surface skin; the first end of the upper surface skin and the first end of the lower surface skin are respectively connected with the rear beam; the other end of the upper surface skin and the other end of the lower surface skin are connected through a rigid trailing edge; the parts, close to the rigid trailing edge, of the upper surface skin and the other end of the lower surface skin, are connected through a sliding mechanism; the sliding mechanism is connected with the rear beam through a shape memory driving part. By adopting the technical scheme, compared with a conventional similar wing, the wing with the self-adaptive variable camber trailing edge has the advantages of simple structure, light weight, low research and manufacturing cost, high flying performance and the like, the aerodynamic performance of an aircraft is greatly improved, the aerodynamic efficiency of the aircraft is improved, the oil consumption is reduced, and the use cost of the aircraft in the whole service life is lowered.

Description

technical field [0001] The invention relates to a wing structure, in particular to a wing structure with self-adaptive performance. [0002] Background technique [0003] Improving the aerodynamic performance of aircraft and realizing efficient, flexible and safe flight has always been the research focus of aircraft designers. With the increase of aircraft flight speed and the diversification of flight tasks, the control surface has been widely used from the early deformable control surface. The rudder surfaces such as front and trailing edge flaps are replaced. Even today, the use of rudder surface control is also faced with the difficulty of adapting to certain flight conditions. Since the wing itself is still approximately rigid, it is difficult to adjust the aerodynamic performance of the wing in real time according to the flight conditions of the aircraft, and the front and rear edge control surfaces adopt a relatively complicated hinge system, which not only increase...
