Book Description
Excerpt from Researches on the Performace of the Screw Propeller Further work with similar propellers of varying pitch ratios was delayed by various causes, but at length this longer program became possible under much improved conditions in the Hydraulic Laboratory at Cornell University, and later through the aid of a grant from the Carnegie Institution, under which auspices the entire work has been reviewed and carried forward to completion so far as this particular series of propellers is concerned. In addition to the work planned under the general program, certain special and collateral experimental researches have been included in the work, all of which are noted at appropriate points in the present report. A preliminary and partial report on this work was made in the form of a paper read before the Society of Naval Architects and Marine Engineers in the fall of 1905 and from which extracts will be made in the course of the present more complete report. The propellers upon which the experiments were made are 49 in number and are distributed over the field of pitch and area ratios as shown by table 1. The diameter of all propellers was 12 inches and the diameter of hub inches. The number of blades was four and the shape of all blades was elliptical, the maximum width in tenths of the radius being expressed by the area number in the table.
