| Abstract: | The dynamic deformation mechanisms of an insect wing in flight were studied by a theoretical modeling approach.The experimental platform for measuring wing's aerodynamic forces designed to demonstrate the 'flexible wedge effect' theory,which could explain the influences of a wing's quasi-static deformation on its aerodynamic forces.The variable stiffness property of the wing was investigated,and it shows superiority and reality when the distribution of flexural stiffness in the chordwise direction is in acc... |
