A numerical approach to determine the optimum circulation of a propeller operating inside a duct and hub is presented. The procedure combines a potential-based panel method for treating the flow around the duct and hub surfaces, and a vortex lattice lifting line method for treating the propeller.The optimum propeller loading is determined by using a non-linear optimization technique to maximize the propeller efficiency. The non-axisymmetric interactions between the duct-hub surface and the propeller are considered within the design procedure. Optimum results for a propeller operating independently with either a duct or a hub are include
