Abstract:

In flight, airfoil changes can significantly improve the aerodynamic performance and enhance the efficiency of aircraft. This paper introduces a systematic method to design compliant mechanisms to carry out airfoil required shape changes. Aiming at certain model unmanned aerial vehicle (UAV), the least square error between the deformed curve and the target curve is defined as the objective function, aerodynamic loads is defined as design condition. Based on variable density method, established the topology optimization model of adaptive wing leading edge which considered geometrically nonlinearity, and solved by using the method of moving asymptotes. Analyzing the results by ANSYS and experimental. The results show that the adaptive wing leading edge could make its shape change from 0 to 7.22 degrees. The experimental data show the feasibility of this approach.
