碩士 === 國立臺灣大學 === 造船及海洋工程學研究所 === 89 === A propeller design method for considerations of both the tip vortex cavitation and shaft angle effect for high speed propeller is developed. A series of non-optimum circulation distribution is established first. Then, the propeller lifting line computation incorporated with tip vortex modeling is developed in taking account of both the efficiency and tip vortex cavitation inception. While the second part is paid more attention on a two-dimensional foil design with consideration of both the cavitation bucket region ( Δα，σx ) and viscous flow characteristic. Finally, the lifting surface design program is applied and the propeller designed for a high speed craft with shaft angle effect is given.
