A TABULATION OF WIND-TUNNEL PRESSURE DATA AND SECTION AERODYNAMIC CHARACTERISTICS AT MACH NUMBERS OF 1.61 AND 2.01 FOR TWO TRAPEZOIDAL AND THREE DELTA WINGSnHAVING DIFFERENT SURFACE SHAPES

摘要

The pressure, section normal-force, and section pitching-moment coefficients for two wings, one flat and one warped, having the same trapezoidal planform and three wings, one flat, one cambered, and one cambered and twisted, having the same delta planform are tabulated. The trapezoidal wings had a 3-percent circular-arc thickness distribution, a taper ratio of 0.721, an aspect ratio of 1.342, and a semispan of 9.815 inches. The delta wings had an NACA 65AOO3 thickness distribution, an aspect ratio of 1.456, 70° of sweepback of the leading edge, and a semispan of 8.735 inches. The wings were tested at Mach numbers of 1.6l and 2.01 with fixed transition at Reynolds numbers of 3.6 X 106 and 3.1 X 106, respectively. Angle-of-attack range was from -20° to 20°.
