STUDY OF PROPELLER WITH SMALL BLADES ON THE BLADE TIPS (CAVITATION CHARACTERISTICS)

The paper reports an experimental study of cavitation performance (cavitation observation, propeller open tests, fluctuating pressure measurement and noise measurement) in uniform flow to compare the characteristics between a conventional propeller and one with a small blade on the blade tips (bladelet propeller). Reduction of cavitation noise and fluctuating pressure amplitude was a direct result of the action of the tip blades by reducing tip vortex strength. A reduction in the sheet cavitation region was also observed. However, some cloud cavitation still occurred at the root of the bladelet.
