High Speed Aerodynamic Characteristics of the GAF0PH Aerofoil

Abstract

Transonic wind tunnel tests are reported on a two-dimensional model of the GAF0PH aerofoil. The tests covered Mach numbers in the range 0.5 to 0.85 and angles of incidence from -3 deg to above maximum life coefficient. Tests were conducted both with natural transition and with transition artificially fixed. Maximum lift coefficient was found to lie just below 0.8 for most of the Mach number range and was followed by a fairly gentle stall. Drag rise Mach number was found to lie between 0.75 and 0.76 for lift coefficients up to 0.4. A leading edge separation bubble was found on the upper surface of the aerofoil for angles of incidence greater than 2-1/2 deg. (Author)
