Scientists at NACA rigorously tested the performance of an exceptionally large NACA 23012 airfoil within their high-tech, specially-designed 7 by 10-foot wind tunnel. Researchers investigated numerous configurations featuring flaps located 25.66 percent along the chord, utilizing unique slot shapes and precise flap deflections to thoroughly determine aerodynamic properties for four distinct design variables: slot form, flap form, flap placement, and the exact amount of flap movement involved. Their research meticulously established specific flap positions required for achieving peak lift as well as generating polars from tested setups, ultimately aimed at facilitating smooth takeoff and ascent procedures. To shed further light on their studies, researchers offered an in-depth evaluation discussing each arrangement's relative effectiveness based on a multitude of chosen criteria, also making side-by-side comparisons with prior flaps developed for the identical airfoil on NACA 23021 to illustrate their differences effectively.
