AbstractThe use of ducted propellers as the quiet propulsive device for UnmannedAerial Vehicles (UAV) is steadily gaining popularity. Their successful application as the fenestron tail rotor is global and well established.This research proposes a comprehensive analysis tool for ducted propellers.In Phase I, an axially symmetric Navier-Stokes flow solver capable of analyzing the ducted fan in climb, hover and descent will be developedand integrated with an intutive graphical user interface. The rotor will bemodeled as an axis-symmetric momentum source in the governing equations. An automated grid generation based on the geomtric characteristics of the duct will be an integral part of the tool. In Phase II, the analysis tool will be extended to non-axial forward flight conditions.
