The ducted propeller designed with the methods based on blade element momentum theory, lift line and panel method has a certain deviation from the real performance due to simplification of the methods. The design and optimization design based on the more accurate CFD method needs a lot of CFD calculation, so the design efficiency is low. To improve the efficiency and accuracy of the design, a design method is proposed based on the blade element momentum theory and CFD modification. The accuracy of the design is improved by modifying the inflow angle and angle of attack, and the reasonable correction coefficient can be obtained by inversely solving the CFD calculation results. After the preliminary design, the ducted propeller which meets the design requirements can be quickly obtained by iterative design that consists of solving the correction coefficient and redesigning. The design of ducted propellers in different states shows that the design method can basically meet the design requirements by two iterations of CFD modification and redesign. The design is efficient and has good design accuracy.
