PROPELLER BLADE SECTIONS WITH ENLARGED CAVITATION BUCKET

This paper describes research aimed at evaluating the possibility of developing new parent sections to use within the traditional propeller design procedure. Using a computer code, three sections were designed having larger cavitation buckets compared with traditional profiles obtained combining a=0.8 mean line and NACA 66 model thickness distribution. For each section the mean line and thickness distributions were calculated and used to obtain a derived foil section. A numerical comparison was then made between and equivalent traditional section and the derived profiles that again exhibited a larger cavitation bucket. Experimental tests validating the numerical results are also described.
