Deformable wing device based on quadrangular star-shaped scissors fork mechanism and variable-length rib plate

Abstract

The invention provides a deformable wing device based on a quadrangular star-shaped scissors fork mechanism and a variable-length rib plate, and belongs to the field of aerospace. The problems that anexisting deformation wing is single in deformation function, only one of variable sweepback, variable area and variable span can be independently achieved, and a large surface deformation rate cannotbe guaranteed are solved. The deformable wing device comprises a quadrangular star-shaped scissors fork linkage framework, a skin, a horizontal driving mechanism and a vertical driving mechanism, a plurality of honeycomb wing ribs are mounted on the quadrangular star-shaped scissors fork linkage framework, a plurality of dimensional stringers are arranged among the plurality of honeycomb wing ribs, the skin is bonded and fixed to the upper surfaces and the lower surfaces of the multiple honeycomb wing ribs, and the horizontal driving mechanism and the vertical driving mechanism are arranged on the quadrangular star-shaped scissors fork linkage framework, and deformation of the quadrangular star-shaped scissors fork linkage framework is achieved through driving of the horizontal driving mechanism and the vertical driving mechanism. The deformable wing device is mainly used for deformation wings.

Description

Technical field [0001] The invention belongs to the field of aerospace, and particularly relates to a deformable wing device based on a four-point star scissor mechanism and a variable-length rib. Background technique [0002] Conventional fixed-wing aircraft are generally designed for the best aerodynamic efficiency in a single flight state, and cannot achieve the best aerodynamic efficiency in all states of the flight envelope. A typical flight mission generally consists of several different operation links, and the aircraft often needs to complete a variety of combined missions. Conventional fixed-wing aircraft can hardly meet the requirements of the aircraft for multi-task execution capabilities. The aircraft needs to face different flight environments during actual flight, which requires that the shape of the aircraft's wing can be changed accordingly to achieve the best aerodynamic performance under different flight conditions. For example, during the cruise, the aircraft ...
