Abstract
This paper describes a rigorous design method for supercavitating propellers (SCPs). The lifting surface correction was directly performed using a vortex lattice method. A circulation distribution was used, which was calculated using Lerb's lifting line theory. Three SCPs were designed, manufactured and tested in a large cavitation tunnel. They all generated the required thrust at the design point except the SCP designed for a higher load condition. The efficiencies obtained were reasonably high for all propellers.
