PROPULSIVE EFFICIENCY AND CAVITATION CHARACTERISTICS OF CONTRAROTATING PROPELLERS DESIGNED FOR A LOW SPEED SHIP

For energy conservation, the development of reliable shafting systems has made contrarotating propellers (CRPs) an attractive alternative with open-water efficiency superior to that of conventional propellers. It is important, however, to also investigate other properties, such as propulsive efficiency, cavitation characteristics and propeller-induced pressure fluctuations. The author describes the essential differences between CRPs and conventional propellers and discusses experimental and theoretical studies showing the advantages of CRPs with regard to these properties.
