Open publisher page 1 citations

Abstract

Contrarotating Propellers (CRP) are one of the most attractive propulsion devices, which can be expected to improve considerably the propulsive efficiency. Although the major problem appears to be related to the mechanics the uncertainty of the CRP efficiency behind the hull also deters shipbuilders and shipowners. The paper deals with this problem using the simplified propeller theory and the interaction theory between CRP and the rudder. See also Abstract No. 88020394 (Feb. 1988).
