A procedure is presented for obtaining the pressure distribution in a two-dimensional, incompressible, and nonviscous flow on an arbitrary airfoil section in cascade. The method considers directly the influence on a given airfoil of the rest of the cascade and evaluates this interference by an iterative process, which appeared to converge rapidly in the cases tried (about unit solidity, stagger angles of 0 and 45 degrees).
