, p = the pitch of the propeller in feet, Po = the power absorbed by the propeller on the ground, 76 AIRPLANE DESIGN AND CONSTRUCTION N = number of revolutions per second, V = the speed of the machine in feet per second, and p = the efficiency of the propeller, than the relations binding the… … V Since -kiiD is the peripheral speed of the blade tip, —^ measures the angle d that the path of the blade tip makes with the plane of rotation of the propeller (Fig. 65). Now, the angle of incidence i of the blade with respect to its path, is measured exactly by the difference B — d; as 6 is…
