EVALUATION OF LIFTING-SURFACE PROGRAMS FOR COMPUTING THE PRESSURE DISTRIBUTION ON PLANAR FOILS IN STEADY MOTION

The pressure differences, forces, and moments on the same two wings in steady subsonic flow were computed by 15 different programs. These results were compared with each other and with available experimental data. Nine of the programs gave predictions that were generally in close agreement with each other and with the experimental results, four showed moderate differences, and the remaining two showed significant differences.
