The characteristics of a Clark y wing model equipped with several forms of low-drag fixed slots
This is a 1933 NACA-era aeronautical technical report by the NASA Technical Reports Server collection, presenting wind-tunnel measurements of a Clark Y wing model fitted with several slot arrangements, written for aeronautical engineers. The first picture plots lift and drag coefficients against angle of attack, and the second sketches wing cross-sections with auxiliary airfoil and gap dimensions, offering designers a clear reference for how slotted leading edges shape performance curves and airfoil profiles.
