Abstract

17,133. Ewart, J. W. July 26. Screw and like propellers. - Propeller blades are of triangular shape, the base being at the boss and the apex at the tip. Each blade is bent so as to be curved axially and transversely. The leading edge c of the blade, shown in Fig. 1, passes into the base a with a free sweep d, and the trailing edge e is curved and lies in a plane perpendicular to the base. The apex is curved as shown.
