This report is concerned with the results of an investigation to determine the effects of simulated skin wrinkling of the wing surfaces on the aerodynamic characteristics of two wing-body combinations. The lift, drag, and pitching moment of a low-wing wing-body combination employing a plane triangular wing of aspect ratio 3 with and without simulated skin wrinkles on the upper surface of the wing are presented for a range of Mach numbers from 0.60 to 0.92 and from 1.20 to 1.90 at a Reynolds number of 4.8 million.
