Abstract

A method is described for the calculation of two-dimensional unsteady inviscid transonic flow about thin airfoils, including shock waves. This method, a so-called field panel method, is based on the solution of an integral equation which combines a subsonic lifting surface panel method with subsonic source panels in the flow. These source panels account for nonuniformities in the velocity distribution due to airfoil thickness and incidence. For a NACA 6hA006 and for a NACA 6UA010 airfoil transonic results are presented and compared with results of the LTRAN2-NLR code. The good agreement obtained shows the feasibility of the method. The lower computer cost makes this approach attractive for extension to 3-D flows.
