PROPELLER BLADE SECTIONS WITH IMPROVED CAVITATION PERFORMANCE

Presently available methods for designing custom propeller blade sections are laborious and may result in section shapes which do not form a consistent family, thereby causing difficulty in fairing along the blade span while maintaining desired section characteristics. This paper presents a methodology for generating foils with the desired properties which will form a smoothly varying family along the blade span. Sample foil designs are presented, along with a discussion of their characteristics. In addition, a simplified method of designing selected foil sections with properties superior to the conventional NACA sections is presented. The information required to create these sections is presented on tables and graphs so that the sections can be designed without special computer programs.
