Analysis of Experimental Data for Cast 10-2/DOA2 Supercritical Airfoil at High Reynolds Numbers (Analyse de Donnees Experimentales pour le Plan Supercritique Cast 10-2/DOA2 en Fonction de Nombres de Reynolds Eleves).

Abstract

Experimental data obtained in the NAE Two Dimensional Test Facility for CAST 10-2/DOA2 supercritical airfoil have been analyzed for the effects of Reynolds number, transition fixing and Mach number. The data were obtained for Reynolds numbers from 6 to 30 million and Mach numbers from 0.3 to 0.8 with fixed and free transitions. The analysis indicates that the aerodynamic parameters of the airfoil depend strongly on Reynolds number and transition fixing. Above Reynolds number 10 million the trends of dependency on Reynolds number with free or fixed transition can be established. For lower Reynolds number, the long stretch of laminar boundary layer over the airfoil alters the flow characteristics significantly and the data do not follow the trends for high Reynolds numbers. Keywords: Supercritical wings, Reynolds number, Airfoils - Supercritical, Canada.
