Exact free streamline solutions are found for two dimensional inviscid incompressible flow past a single and a multiple flap wing using a hodograph method. It is shown that solutions do not exist for arbitrary shapes, but that a geometrical constraint must be satisfied between the shape of the wing and the angle of attack. High lift coefficients are obtained for both cases. These solutions model the flow situation for a wing claimed in the past to give high lift at low speed.
