ucing a break in the air flow that materially reduces the value of the maximum lift. For instance, a wing with a 2-inch chord at the tip and a 3-inch mean chord, gives a uniformly better performance than a similar constant section wing, but if the tip is reduced to 1| inches, with the same mean… … 3 inches wepe cut off of each tip, leaving an 18-inch span and a 2-inch chord at the tip (Fig. 24), the maximum Lc was increased to 0.00413. This does not prove, however, that on a full-sized machine, where the LV is large, a small chord at the tip is a disadvantage. For f.his same reason it seems…
