Compliant mechanisms are arranged to enable airfoil and other structures to adapt their shapes to different flight conditions and thereby achieve optimum lift:drag ratios in plural flight conditions. The compliant mechanisms can be formed integrally whereby a compliant frame thereof, or the skin of the airfoil, undergo elastic or other deformation to produce the desired displacements in direct response to applied forces. In an airfoil context, shape changes can be effected by the leading and trailing edges of the entire airfoil system. In addition, the d...
