e coefficients for each diameter Pn2 and pitch setting were plotted against J^- Typical where V is the velocity of advance and P represents examples of these plots are given in Figures 6 to 9, the power absorbed by the propeller. Propellers inclusive. The coefficients read from the faired curves… … Figure 2.—Propeller series of five diameters Figures 10 to 21, inclusive, give the thrust coeffi- velope of the efficiency curves of Figures 22 to 26, cient, power coefficient, and propulsive efficiency inclusive, and also the ~jj for maximum efficiency curves for the different diameters for…
