Design-oriented high-lift methodology for general aviation and civil transport aircraft

A high-lift system design methodology that can be incorporated during the early stages of aircraft development is presented and thus has the potential to provide a superior and more cost-effective vehicle than one developed utilizing traditional linear design methods. The present methodology offers two different levels of e delity: one applicable to the conceptual design stage and the other to the preliminary design stage. The underlying e ow solver couples a three-dimensional nonlinear Weissinger method with two-dimensional viscous data to provide fast and accurate aerodynamic predictions for high-lift cone gurations. Several test cases that illustrate the capabilities of this hybrid e ow solver are presented.
