Comparison of calculated pressure distributions on some swept wings with Warren 12 planform at suhsonic speeds

Abstract

Data are presented from calculations for the surface pressure distribution on some particular swept wings vrith Uarren 12 planform. The calculations were made using the method described in Royal Aeronautical Society Transonic Data Memorandum 6312. Comparisons are given between results obtained from an RAE computer program and a similar program developed at NLR. It is shown that small differences exist as a consequence of different numerical procedures and slight changes in formulation of the basic method. Additional comparisons with a numerical solution of the exact equation for incompressible potential flow suggest that thickness effects are reasonably well represented for the configurations considered.
