Airfoil Search |
You can search an airfoil according to its name, its geometry characteristics, or its performances. By now, Upwhirlwind provides 1710 (util 2025-01-16) airfoils' performance in a serials of Mach and Reynolds numbers. The Mach number is range from 0 to 0.5 with interval 0.1; The Reynolds number is one of 50000, 100000, 500000, 1000000 or 5000000. |
