EXPERIMENTAL INVESTIGATION OF OSCILLATORY AERODYNAMIC FORCES, MOMENTS, AND PRESSURES ACTING ON A TAPERED WING OSCILLATING IN PITCH AT MACH NUMBERS FROM 0.40 TO 1.07
Abstract
Data were obtained for an aspect-ratio-3, taperratio-0.5 wing oscillating + or - 1.5 degrees about mean angles of attack of 0, 5, and 10 degrees. Results of the experimental investigati n are c mpared, in the subsonic Mach number range, with those obtained by use of a theoretical analysis based on a numerical solution of the integral equation of subsonic lifting-surface theory. Comparisons with theory of the measured force, moment, and pressure coefficients and their respective phase angles, when the wing was at a mean angle of attack of 0 degrees, showed generally good agreement.
