Abstract : An analytical study is made of the flow past hydrofoils with large camber at arbitrary angles of attack. The class of hydrofoils considered is restricted to those whose hodograph plane has a shape very near that bounded by two circular arcs. Under this assumption a general method is derived to calculate the parameters of the flow. In addition, a short-cut procedure is introduced for estimating the lift and drag coefficients. As a numerical example to illustrate the theory the flow past a circular-arc foil is considered. The force coefficients are in good agreement with the values computed by Rosenhead.
