description abstractA low-speed wind-tunnel investigation has been made at a Reynolds number of 0.9 X 106 to determine the longitudinal aerodynamic characteristics of a double slotted flap on a wing swept back 35º at the quarter chord. The wing had an aspect ratio of 7 and a taper ratio of 0.3. The flap was 0.33 wing chord and the vane was 0.50 flap chord.
A maximum lift coefficient of 2.2 was obtained with the double slotted flap in conjunction with a leading-edge slat. The lift coefficient increment at a = 0º and δf = 70.7º was 1.43. This value was predicted by a method presented in NACA Technical NOTE 3911.
