PROPELLERS FOR HIGH-PERFORMANCE CRAFT

This paper presents a brief historical review of marine propeller development leading to modern design, selection, and matching methods for high-performance craft such as planing hulls, hydrofoils and surface effect ships. Subcavitating propeller theory is summarized, and some limitations are discussed with regard to high-speed applications. An outline of supercavitating propeller theory is provided together with brief details of design procedures and the limitations of available data. The special problems of application of supercavitating propellers to surface effect ships are discussed briefly. Topics include sidehull installations, matching for hump and cruise, need for partial submergence and controllable pitch, strength considerations, and model versus full-scale performance. A review of recent progress in the application of supercavitating propellers to surface effect ships is presented, including comparisons of predicted full-scale blade pressures and stresses with actual full-scale measurements of speeds up to 80 knots. Future trends and goals are discussed, including development of improved performance prediction methods, rational structural design procedures, and new types of installation configuration. Much of the new information contained in this paper arises out of work performed under contract for the U.S. Navy Surface Effect Ship Program Office (PMS304) by Bell Aerospace Textron.
