ABSTRACT | Two-dimensional transonic wind tunnel tests of thin airfoils were made as a part of aerodynamic research on propeller blades for advanced turboprop engines. The test airfoils were NACA-16-202 and NACA16-204 which were developed as airfoils for conventional propeller systems at NACA in 1934. The Reynolds number is 8×106. The Mach number was varied from 0.6 to 1.0 and angles of attack from -10 to +16. In addition, vibration characteristics were measured and analyzed. |
