Abstract : A comprehensive evaluation is made of six computer programs that analyze thin wing lifting surfaces in steady subsonic flow. The programs are compared with one another and with available experimental data for a total of 62 planform cases, 18 camber cases, and two flap cases. For the planform cases, four of the programs were generally in good agreement with each other and with experimental results, one program showed moderate differences, and the remaining program showed large differences. The agreement predicted and experimental results was erratic for the camber cases and poor for the flap cases. (Author)
