Abstract:

Making aircraft wing vary under different flying speeds is a key technology of variable camber adaptive wing. Although conventional hinged mechanisms can change the wing shape in response to the change in flying speed, the connecting hinges create discontinuities over the wing surface, leading to earlier airflow separation. Genetic algorithm(GA) is used to synthesis fully the compliant mechanisms that can deform an initial shape into a target shape with a continous smooth boundary.
