Abstract
In this paper, the ducted propeller configuration is optimized using the geometry parameterization method and proposed Newton method with the total system thrust as the optimization objective and the maximum torque as the constraint. Based on the initial model, the propeller geometry is optimized by decoupling the ducted propeller, and iterations are carried out until the optimization converges. The propeller optimization primarily consists of an increase in the thickness of the propeller root wing and the torsion angle of the middle wing, and a reduction in the curvature of the propeller tip. The ducted propeller system has a 6.29% improvement in thrust after aerodynamic optimization.
