Abstract
Compares theoretical analysis results with experimental wind tunnel data at chord Reynolds numbers below 500000. The methods studied are the Eppler/Somers and Drela/Giles aerofoil codes. For Re exceeding 200000 lift and moment predictions agree with experimental results obtained in the Langley low turbulence pressure tunnel. Drag predictions are in reasonable agreement, and the Drela/Giles code predictions for pressure distributions agree with experimental data, including cases with laminar separation bubbles. At lower Reynolds numbers, lift and moment predictions are in reasonable agreement, but drag predictions tend to be accompanied with separation bubble warnings (Eppler code). Only the drag polar predictions of the Drela/Giles code agree (qualitatively) with experiment. (from authors' abstract)
