A TABULATION OF SECTION AERODYNAMIC CHARACTERISTICS AT MACH NUMBERS OF 1.61 AND 2.01 FOR FOUR SWEPT WINGS HAVING THE SAME PLATFORM BUT DIFFERENT SURFACE SHAPES

Abstract

The section normal-force and pitching-moment coefficients for four sweepback wings with different surface shapes are tabulated. All the wings had NACA 65A005 thickness distributions, 50 degrees of sweepback at the quarter chord, a taper ratio of 0.20, and an aspect ratio of 3.5. There were three twisted wings and one flat wing. The twisted wings had 6 degrees of washout at the tip, but the twist variation along the span was either linear, quadratic, or cubic. The wings were tested at Mach numbers of 1.61 and 2.01 with fixed and free transition through a Reynolds number range of 1.7 to 3.6 x 10 to the 6th power. Angle-of-attack range was from -20 to 20 degrees.
