Skewed propeller angle is one of the most effective design providing a significant
advantage on increasing efficiency of the high-speed propeller. The project presents
a Computational Fluid Dynamic (CFD) approach to predict thrust, torque, and
efficiency of the skewed propeller. Several parameters such as Revolution per Minutes
(RPM), pitch ratio (P/D), blade number and skewed angle of the propeller have been
taken into account in various advanced number. The CFD results showed that skewed
propeller with 5-7 blades has the most ideal properties with increasing thrust and
decreasing torque as RPM increases. The efficiency of propeller also increases to
190RPM and drop drastically after then. Finally, the analysis suggests the most
practical skewed propeller angle for maximum efficiency and minimum torque.
