Abstract

Within the European Union FASTPOD project the application of electric drive podded propulsors to high-speed commercial vessels is being studied. In particular a Ropax and a cargo ship have been selected as candidates for speeds of 35-38 knots. For such high speeds the hydrodynamic design of the propeller with its housing is critical due to the danger of cavitation on both propeller blades and supporting strut. This paper deals with the optimization process of the propeller housing using RANS solver FINFLO. A non-symmetric strut is designed in order to delay cavitation inception keeping at the same time low drag and low lateral forces on the strut. A remarkable reduction of low-pressure areas is observed on the strut surfaces for a tailor-made design as compared to a conventional symmetric strut. Several pod configurations are also analyzed.
