Acoustic wind tunnel tests were conducted of a two-dimensional wing section with removable high-lift leading and trailing edge devices and a removable two-wheel landing gear with open or closed cavity. An array of far field conventional microphones and an acoustic mirror directional microphone were utilized to determine far field spectrum levels and noise source distributions. Data were obtained for the wing with components deployed separately and in various combinations.
