ABSTRACT:
A novel concept for a wing or airfoil incorporates the model of the natural wave behavior. The leading edge of the airfoil is parallel to the trailing edge, but offset by a given amplitude. The surfaces between the leading and trailing edges are rounded so as to promote proper fluid sheet formation along the surface and to reduce undesirable vortice formation. Best results are obtained by modeling the surfaces along a sine or tangent function.
