Abstract: A critical review is presented on methods of surface distribution of singularities around multielement arifoils in plane potential flow analysis. The approach of piecewise constant distribution of vorticity, used originally for airfoils, is treated here to develop a numerical method for multielement cascades. The incompressible flow pattern is obtained by superimposing solutions for 3 × N prescribed onset flows around an N-element cascade system. Compressibility effects are treated by an extension of Goethert’s rule involving affine transformation. Emphasis is placed upon a comprehensible description of the problem formualtion and, in particular, on deriving the correct circulation strength around multiply-connected domains. Some results are presented and discussed.
