A report describes wind-tunnel experiments on a rectangular supercritical wing and presents test cases that have been selected from the archived sets of experimental data for comparison with computational fluid dynamics (CFD) predictions. In the experiments, the wing was driven in pitching oscillations at frequencies below the lowest natural vibration frequency of the wing. The data obtained in the experiments included the static pressures and the in-phase and quadrature components (with phases referenced to the pitching motion) of unsteady pressures at a number of points on the upper and lower wing surfaces.
