DESIGN OF HIGH PERFORMANCE SUPERCAVITATING PROPELLERS BASED ON A VORTEX LATTICE METHOD

This paper describes a rigorous design method for supercavitating propellers (SCP). An optimum circulation distribution was calculated by Lerbs' lifting line theory. Lifting surface correction based on a vortex lattice method was directly made by using the most favourable load distribution based on a non-linear supercavitating flow theory. Three SCPs were designed and they all generated the required thrust at the design point except the highly loaded one. The efficiencies were reasonably high for all propellers. It is concluded that the method is one of the most promising and reliable tools for designing high performance SCPs.
