A Survey of Cyclical Propulsion

Abstract

This report presents a brief history of cycloidal propulsion and a description of the kinematics of the flow through a cycloidal propeller. The various types of cycloidal propellers are discussed and a description of several installations is presented. A survey is presented of the literature pertaining to theoretical design procedures used for cycloidal propellers. A comparison of cycloidal and screw propulsion shows that cycloidal propeller efficiency is in the range 0.45 to 0.58 as compared to 0.66 to 0.76 for screw propellers. Some advantages of cycloidal propulsion are discussed. In order to insure optimum efficiency in designs of the future, it is recommended that research be carried out to find the influence of: Kramer's effect, a lifting surface passing through a vortex sheet, wake contraction, blade motion, wake adaption and blade proportions.
