Fig. G3. All propellers having the same type of profile, are said tobelong to the same family. Numerous laboratory experiments on propellers, byColonel Dorand, have demonstrated that there exist cer-tain well-determined relations between the elements of … Fig. 64. propellers that are of the same family and geometricallysimilar, so that once the coefficients of these relations areknown, it is easily possible to obtain all the data for thedesign of the propeller. Let D = the diameter of the propeller in feet, p = the pitch of the propeller in feet, Po…
