Abstract
26,274. White, Sir W. H., [Taylor, D. W.]. Nov. 12. Screw propellers. - In order to avoid the h a r m f u l effects of cavitation. each blade is formed with a h o l l o w or concaved back, extendirg from the leading edge, and preferably merged into the usual curved or convex back, which may be serrated and ribbed at the leading edge. Figs. 7 and 8 show such a blade, in which the angle between the face and the back at each point of the leading edge 7<1> is sharp and approximately equal to the slip angle, and the back of the blade adjacent to the leading edge is of decreasing pitch. Fig. 11 shows a blade which has the leading edge serrated, and supported by ribs beveled or sharpened at their leading ends. Specification 3466/08 is referred to.
