INVESTIGATION ON THE DUCTED PROPELLER CAVITATION AND THE DUCT EROSION PREVENTION BY THE AIR INJECTION SYSTEM

The results of full scale investigations are presented including cavity thickness contours on the propeller blades obtained by analysing the stereo photos, and the effect of air injection is discussed from various aspects.
