DEVELOPMENT OF MARINE PROPELLERS WITH BETTER CAVITATION PERFORMANCE, 1ST REPORT: PROPELLERS WITH LESS CAVITATION

New propellers with better cavitation performance in comparison to that of MAU type were designed, matching the equivalent two- dimensional foils obtained from lifting surface calculations with those obtained from foil section design theory by prescribing the pressure distribution. In designing the new propellers only the section shape and pitch were altered, keeping all other parameters the same as for the MAU type. Flat pressure distribution except near the leading edge, was adopted so as to give less cavitation, based on experimental results of two-dimensional foils that were presented in a previous paper.
