Completely retractable flexible variable wing mechanism

Abstract

The invention discloses a flexible variable-wing mechanism capable of completely shrinking, which is used for realizing bird-like variable-wing flight of an aircraft in a flight process and realizing the flight of the aircraft at different flight speeds and heights in an optimized aerodynamic layout by changing the shape of a flexible missile wing. The flexible wing changing mechanism is composed of an aircraft main body, a main driving rod with a turbine, a flexible skin, a framework, two motors, a worm coaxially connected with the motors, a torsional spring and an end cover. The two ends of the flexible skin are fixed to the framework and the torsional spring respectively, the flexible skin is unfolded and keeps certain rigidity by means of tension of the framework and the torsional spring, and different missile wing flexible deformation is achieved through different included angles between the framework and the missile body. When the flexible missile wing does not need to be unfolded, the flexible missile wing is wound on the torsion spring shaft completely by means of the directional tension of the torsion spring, and complete contraction is achieved. The variable wing mechanism has the characteristics of light weight and small occupied space, and can effectively improve the load of a flying body.
