STATIC PRESSURE DISTRIBUTIONS OVER 2D MAST/SAIL GEOMETRIES

Abstract

A variable-camber airfoil with integral pressure tappings has been built to investigate the nature of the flows around two-dimensional, highly cambered, sail-like airfoil sections with circular masts. Data have been obtained in the form of static pressure distributions over representative ranges of Reynolds number, camber ratio, incidence angle, mast diameter/chord ratio and mast angle. Two sail shapes--based on the NACA a = 0.8 and NACA 63 mean-line camber distributions--were involved in the test program. All flow regimes present have been identified and related to the salient model and flow parameters.
