162 REPORT NATIONAL ADVISORY COMMITTEE FOR AERONAUTICS. detail here. Over a considerable range of all the graphs the computed values agree closely with the observed values for raked tips; but in the region of maximum lift the computed values are increasingly too large. . … Fio. S.—Sloane aerofoil. LJft coefficient for various tips. Air Fio. 9.—R. A. F. 6 aerofoil. Lift coefficient for various tips, speed 35 m. p. h. Air speed 35 m. p. h. Though no general conclusions can be drawn from such a limited study, it furnishes some evidence in favor of the common practice of…
