Abstract
According to the relationship between aerodynamic loads and elastic deformation of wings, a new method is proposed for stiffness design considering aerodynamic and structural coupling. It takes the strength and the constant total lift as constraint conditions. This paper firstly studies the influence of wing bending and twist deformation on aerodynamic loads through numerical experiments, and a response surface model of aerodynamic loads and wing deformation is established by using principle component regression. Then, based on the response surface model, an integrated aerodynamic and structural design is made. Disregarding bending and twist deformation in the optimum wing structure, the method only considers the strength and the constant total lift constraint. Compared with two kinds of optimum models, the result shows that the method reduces 1.23％ of the weight and 33％ of global twist deformation of wings, thus the stiffness design is more reasonable.关键词
