Abstract

The fast and accurate method presented for obtaining the early evolutionary stages of an initially planar, finite-span vortex sheet can be used to determine wing downwash behind a wing, in such regions as the vicinity of the tail plane. The solution is expressed as a power series in time whose coefficients are calculated via proper numerical evaluation of the accompanying Cauchy integrals. The method does not discretize the vortex sheet. (O.C.)
