Marine propellers design requirements are always more pressing and the application of unusual propulsive configurations, like ducted propellers with decelerating nozzles, may represent a valuable alternative to fulfill stringent design constraints. Accelerating duct configurations were realized mainly to increase the propeller efficiency in the...

The aim of this study is to experimentally investigate the cavitation erosion on the blade root of a model scale controllable pitch propeller. Tests are carried out in a cavitation tunnel, using the soft paint technique to study cavitation erosion, exploiting also two standard cameras and one high speed camera to study the damage patterns and...
