An airfoil having a device for changing the spacing between the airfoil\s surface panels, thus to change the aerodynamic property of the airfoil. Considering the airfoil as in the case of the airfoil being a part of an airplane wing, the airfoil carries a flap panel along the wing\s front edge, the
An airfoil having an upper panel means and a lower panel means, operatively interconnected, and which are spaced apart and shaped to have aerodynamic airfoil property when in forward motion relative to the surrounding air, the airfoil having means for changing the spacing of the panel means, thereby
