Asymptotic and computational methods have been utilized to study the incompressible and transonic flow over upper surface blown airfoils. To provide a framework for other approximate simulations which are subsequently discussed, a full potential formulation is indicated. In this and other models, the problem has been decomposed into the treatment of the fine structure of the jet and the analysis of the flow outside it. Asymptotic expansions of limit process type have been used to treat the jet in a thin layer approximation using suitable strained variables.
