Abstract：In view of influence of multi-control surfaces on static aeroelasticity of two-dimensional wing,the model used in this paper is based on two dimensional wing with leading-and trailing-edge control surfaces and the location of elastic axis at the back.Based on the CFD/CSD loose coupling static aeroelasticity numerical calculation method,the aerodynamic characteristics and torsional deformation of two-dimensional wing with different deflection modes of control surfaces are calculated and analyzed under condition of Ma=0.3.The results indicate that when leading-and trailing-edge control surface deflect clockwise,the aerodynamic characteristics is bad while torsional deformation characteristics is good,and peak of torsional angle (θmax)decreases about 43.32%~62.92% compared with the basic wing.When leading-edge control surface deflects anticlockwise,the situation is contrary,the maximum of lift coefficient (Clmax) increases about 42.96%~57.58% and stall angle of attack decreases about4°.The study can provide reference for the application of multi-control surfaces on active control of aeroelasticity of forward swept wing.
