A family of five and six-bladed SRI・B propellers suitable for high speed ship, especially from a view point of cavitation characteristics, was developed. Preliminary studies on optimum shape of blade section were made from a view point of cavitation characteristics based on the pressure distributions on the corresponding two dimensional wings which were calculated by the lifting surface theory and the cavitation tests of the propellers in a uniform flow. Systematic open water tests of the family have been carried out and the propeller performances were expressed as polynomials of advance coefficient and pitch ratio of propellers. From the results of open water tests, √<B_p>-δ design diagrams were presented. It was clarified that cavitation characteristics of the SRI・B propellers were superior comparing with that of the MAU propellers by means of cavitation erosion tests using a soft surface method in a non-uniform flow.
