| Abstract: | To solve the complex flow field problems and make more improvement on the aerodynamic performance of the ducted fan, a refined analytical model of aerodynamic performance for ducted fan on the ground of CFD and momentum-source method is built. The effect of design parameters on aerodynamic performance of ducted fan is clarified. The parameters of duct fan is optimized by which the aerodynamic performance of the ducted fan is improved and the lift of ducted fan has increased by 27.58% . |
