Application of an improved unified subsonic-supersonic potential flow method for the aerodynamic analysis of aircraft configurations

F. A. Woodward, under contract to the NASA Langley Research Center, has recently formulated a distributed vortex aerodynamic singularity and developed an improved unified subsonic-supersonic potential flow computer program employing this singularity. This improved program is applicable to the prediction of the local surface pressure distribution for a large class of essentially arbitrarily shaped aircraft configurations. Results are presented for two classes of aircraft configurations of current interest: a maneuvering fighter type and a supersonic transport type. Comparison of these results with experiment indicate the program has good prediction capability.
