Variable camber wing trailing edge based on compliant mechanism

Abstract

The invention relates to a variable camber wing trailing edge based on a compliant mechanism. The variable camber wing trailing edge based on the compliant mechanism is fixed at the rear end of a wingand provided with an elastic upper trailing edge skin and an elastic lower trailing edge skin. The trailing edge upper skin is fixed to a wing upper skin; and the trailing edge lower skin can retractinto a wing lower skin. An upper surface skin and a lower surface skin are connected by using a compliant driving mechanism; a connecting rod mechanism is additionally arranged between two points, with invariable distance, of the wing upper and lower skins before and after the deformation of a wing trailing edge to restrict the shape of the wing in the deformation process. Under the driving of adriving motor 1, the variable camber wing trailing edge based on the compliant mechanism enable a driving force to act upon the trailing edge skins by using the compliant mechanism so as to drive thetrailing edge upper skin to be bent downwards; and under the action of a driving motor 2, the trailing edge lower skin of the wing is driven to retract into the wing and is bent downwards. Through theadoption of two driving devices, the flexible trailing edge is guided to deform so as to change the aerodynamic performance of the wing.

Description

Technical field [0001] The invention belongs to the technical field of aviation equipment, and in particular relates to a trailing edge of an aircraft wing with variable camber based on a compliance mechanism. The trailing edge of the compliant wing includes an elastic wing skin and a compliant drive mechanism. The trailing edge of the wing provided by the invention can realize continuous and smooth variable camber deformation, which improves the aerodynamic performance of the aircraft under different flight conditions. Background technique [0002] The key indicators of aircraft maneuverability, flexibility, and energy consumption are very dependent on the airfoil design of the aircraft wing. The traditional aircraft basically keeps the initial geometric design unchanged during flight, so under different flight conditions, it can only maintain the same aerodynamic performance. By deliberately changing the wing shape during flight (such as wing sweep angle, wing span, wing camb...
