The author performed cavitation test (cavitation observation, propeller open test, fluctuating pressure measurement and noise measurement) in uniform flow to compare the characteristics between the conventional (original) and the propeller with small blade on the blade tips (bladelet propeller). From these test, it was suggested that the reduction was confirmed about cavitation noise and fluctuating pressure amplitude, due to the reduction of the strength of tip vortex by the small blades, compared with the conventional propeller, which was observed at the model tests as shown in the first report. The reduction of sheet cavitation region was also observed. However, the cloud cavitation was occurred at the root of bladelet.
