Some measurements were made of the aerodynamic forces and moments acting on a rectangular wing of aspect ratio 2 which was oscillated about the midchord. These measurements were made at four frequencies (31, 43, 54, and 62 cps) over a range of Mach number from 0.15 to 0.81, a range of reduced frequency from 0.15 to 1.32 and a range of Reynolds number from 0.60 to 10 (sup 6) to 9.21 X 10 (sup 6).
