Problems solved by technology

However, in this kind of variant scheme, the gap flow between the canard and the fully forward-swept wing will interfere with the flow around the wing and the fuselage. At present, there is no reliable and effective canard and forward-swept wing overlapping mechanism, so that The aerodynamic gain of this scheme is greatly reduced

Abstract

The invention relates to a variable forward swept wing and canard overlapping mechanism and a working method thereof, relates to the technical field of wing mechanisms of aircraft, and solves the technical problem that the slot flow between a canard and a fully forward swept wing interferes with the flow around the wings and a fuselage. The variable forward swept wing and canard overlapping mechanism concretely includes a canard and a forward swept wing. The canard and the forward swept wing are respectively arranged on the two sides of a fuselage, the forward swept wing is arranged at the front end of the canard, the wing tip side wall surface of the forward swept wing is provided with a spar in the chordwise direction, and the wing tip side wall surface of the forward swept wing is covered with a flexible skin structure; and a drive system is also arranged inside the flexible skin structure, and the drive system drives the spar to drive the flexible skin structure to smoothly and continuously deform. As the flexible skin structure is arranged at the outer end of the forward swept wing, the drive system drives the spar to drive the flexible skin structure to smoothly and continuously deform; the shape of the forward swept wing is driven by the spar to change, and then the distance between the forward swept wing and the canard is changed, and finally the seamless overlapping ofthe two is achieved.

Description

technical field [0001] The invention relates to the technical field of aircraft wing mechanisms, in particular to a variable forward-sweep wing and canard overlapping mechanism and a working method thereof. Background technique [0002] The morphing aircraft can change the shape of the aircraft locally or as a whole, so that the aircraft can adapt to the needs of various missions in real time, and maintain optimal efficiency and performance in various flight environments, improve ride comfort, and reduce operating costs and environmental impact of noise . In the development process of aviation technology, the concept of variant design is constantly reflected, but it is limited to the position change of wings or some parts. [0003] The variable-sweep wing variant aircraft can effectively optimize the lift-to-drag ratio, aerodynamic efficiency, flight speed and maneuverability of the aircraft in real time according to the task and environmental changes through the forward / ba...
