  • For the purpose of optimizing the aerodynamic characteristics and improving the flight efficiency of aircraft, a variable camber wing with multi-stage linkage driving mechanism is studied. The aerodynamic characteristics of the wing at the maximum deformation angle are studied by the fluid analysis function of ANSYS. The structural strength of the driving mechanism under the limit load condition is studied by the static analysis function of ANSYS. The motion of the driving mechanism is studied through simulation analysis and prototype test. The results indicate that the maximum lift coefficient of the deformed wing is 1.4, and the maximum aerodynamic pressure is 1 078 Pa, which is less than the yield aerodynamic pressure of the lower surface of 4 916 Pa. The maximum stress of the driving mechanism is 37.3 MPa, which is less than the structural yield strength of 55.2 MPa. The wing deformation angle is greater than ±25°, which meets the requirement of improving aerodynamic characteristics of aircraft.
