Abstract

On the development and application of oscillating foil propellers P.S.K. Lai*, R.C. McGregor* & N. Bose" "Global Maritime, Maritime House, London, UK ^Department of Mechanical Engineering, University of Glasgow, UK °Naval Architectural Engineering, Memorial University of Newfoundland, St John's, Canada ABSTRACT Three different oscillating foil propulsion systems for marine vehicle application are discussed as alternative propulsion systems to the conventional screw propeller. Some theoretical and experimental results are discussed briefly and the application of these propellers on four ships representing different sizes and speeds of ship are presented. INTRODUCTION People have always been amazed by the high swimming speed of fishes and cetacean mammals. After millions of years of convergent evolution, fast fishes and cetacean mammals possess a similar mode of swimming motion (thunniform) and similar caudal fin shape (a high-aspect-ratio lunate tail). They ar
