Predicted maximum lift coefficient, Cl,max, is overestimated by 0.3 for OVERFLOW and around 0.2 for XFOIL (version 6.94). Details of airfoil (aerofoil)(p51droot-il) P-51D ROOT (BL17.5) AIRFOIL P-51D root. At higher Reynolds numbers, the profile drag coefficient values are in great agreement. This general trend is likely due to difficulty in modeling laminar separation bubbles at low Reynolds numbers. The above input will run the airfoil through angles of attack from -15 to 15 degrees at a Reynolds number of 2900000. At very low Reynolds numbers, all computational methods un-derpredict drag at lift coefficients occurring at the center part of the bucket. Classical computational methods including XFOIL, MSES, and the Eppler program are compared along with OVERFLOW to newly published experimental data of a low Reynolds number airfoil, the PSU 94-097.

Airfoil comparison Reynolds number calc NACA 4 digit generator NACA 5 digit generator Information. Data for the NACA sections has been derived from the book Theory of Wing Sections, by Abbott and Von Doenhoff. This app queries an aerodynamic database of NACA 4 digits, 5 digits, 6 series, and NASA supercritical airfoils. At very low Reynolds numbers, all computational methods un-derpredict drag at lift coefficients occurring at the center part of the bucket. The data surrounding Re values of 1 to 3 million is extensive for powered flight and benefits from the vast catalog of NACA airfoil data. Get airfoil characteristics from an experimental database.
