Investigation of a thin wing of aspect ratio 4 in the Ames 12-foot pressure wind tunnel 4 : the effect of a constant-chord leading-edge flap at high subsonic speeds
Description:
Report presenting wind-tunnel tests of a semispan model of a thin sharp-edged unswept wing of aspect ratio 4 and taper ratio 0.5 equipped with a full-span, constant-chord, leading-edge flap. The effectiveness of the leading-edge flap in improving the lift-drag ratio of the wing was investigated over a range of Mach and Reynolds numbers. Results regarding the lift characteristics, drag characteristics, pitching-moment characteristics, and lift-drag ratio are provided.
