On the Plane Potential Flow Past a Lattice of Arbitrary Airfoils

Abstract

The two-dimensional, incompressible potential flow past a lattice of airfoils of arbitrary shape is investigated theoretically. The problem is treated by usual methods of conformal mapping in several stages----one stage corresponding to the mapping of the framework of the arbitrary line lattice and another significant stage corresponding to the Theodorsen method for the mapping of the arbitrary single wing profile into a circle. A particular feature in the theoretical treatment is the special handling of the regions at an infinite distance in front of and behind the lattice. Impressions are given for evaluation of the velocity and pressure distribution at the airfoil boundary. An illustrative numerical example is included.
