Abstract

Two computer programs STWING and SFL022 (adapted versions of NASA and Jameson's codes respectively) have been made operational on the UNIVAC 1160/H1 computer at NAL. The STWING solves the conservative 3D transonic full potential equation for a wing using the approximate factorization scheme. The SFL022 solves the nonconservative form of13; the transonic full potential equation using a relaxation scheme. These programs have been applied to a typical ONERA M6 wing. Comparisons between the results obtained by these codes have been made with calibrated experimental results. It is observed that both the codes predict the pressure distribution and the shock wave satisfactorily.
