This final report, explain the design and analysis process of fan blade for electric ducted fan engine. This engine will become an alternative engine tor replace quadrotor vehicle. The engine must be able to meet the design requirements and objectives, i.e the MTOW is 15 kg and the rate of climb is 9 m/s at sea level. This engine uses an electric motor as its drive, so it requires a well designed blade which is appropriates with the excisting electric motor on the market. <br /> <br /> <br /> <br /> <br /> The fan is designed by using an analytical method, i.e blade element theory and momentum theory. The analysis is then conducted analytically and numerically. The numercial method is employed to validate the result of analytical method. The software used for Computational Fluid Dynamics (CFD) simulation is ICEM CFD and ANSYS CFX <br /> <br /> <br /> <br /> <br /> The analytical method analysis shows that the designed fan perform well at its designed RPM and air volume flow, while CFD simulation shows 10% difference in generated thrust at its desgin point. The differences between analytical and numerical method is probably due to differences in pressure rise. At off-design condition, the analytical and numerical analysis commonly shows good agreement. The maximum differences between both method is 18% at 1400 RPM and 7.166 m3/s.
