The results of the clean wing configuration are shown in Table 1. Figures 6 - 8 show all three coefficients vs angle of attack, α, for all four configurations. From Figure 6, both the flap and slat enhanced the lift coefficient, but in different ways. Comparing the clean wing and the slat lift curve, the two curves are almost overlapping at low angles of attack. The clean wing lift curve peaks to about 0.9 at 12°, but the slat curve continues to rise to 1. 4 at 18°. This in

Lift generation can be enhanced by the deployment of high-lift devices, such as flaps and slats. Most airplanes are equipped with flaps, and all commercial transport airplanes have both flaps and slats. It is critical to characterize the performance of a wing with flaps and slats during aircraft development.

In this demonstration, a Clark Y-14 wing with a flap and a slat was evaluated in a wind tunnel. The forces and moment measurements were collected to determine the lift, drag and pitching m
