Numerical analysis method of aerodynamics-structure coupling for aircraft wings

HU Jie,YU Xiongqing(Key Laboratory of Fundamental Science for National Defense-Advanced Design Technology of Flight Vehicle,Nanjing University of Aeronautics and Astronautics,Nanjing 210016,China)  
As to the problem of static aerodynamic elasticity of aircraft wings,a practical effective simulation method on aerodynamics-structure coupling for aircraft wings is studied to predict the aerodynamic characteristics more exactly.Taking the design of passenger aircraft wing as an example,a simulation analysis platform of aerodynamics-structure coupling is built by the static aerodynamic elasticity analysis and the decomposition of aerodynamics-structure coupling for wings,which is parametrized,automatized and modulized.The process of the platform includes aerodynamic analysis based on full potential equation,structure simulation based on MSC Nastran,transmission from load to structure model using MATLAB,mapping from structure deformation to aerodynamic shape,and so on.An example shows that the problem of static aerodynamic elasticity can be solved satisfactorily by the method.
