Development of aeroelastic modeling and analysis for wing camber morphing technology

Abstract

As one of the morphing methods, wing camber morphing technology has received great attention. Starting from the relevant projects of morphing wing at home and abroad, the aeroelastic modeling and analysis means of the camber morphing technology are focused on in this paper. Static aeroelasticity, flutter, dynamic aeroelasticity response and alleviation, optimization and control are analyzed. Different research means are evaluated from the perspective of structural model, aerodynamic model, coupling method, optimization method and control strategy. The technical difficulties currently facing are analyzed. The problems that are necessary to be further resolved, including the influence of the nonlinear behavior of the flexible skin on the aeroelasticity of the variable camber wing, the influence of actuator system on the aeroelasticity and the lack of a comprehensive aeroelastic modeling method that can handle different nonlinearity are pointed out in order to provide guidance for the further improvement of the camber morphing technology.
