title = "A computational and experimental analysis of a ducted fan used in VTOL UAV systems",
abstract = "Ducted fan based vertical/short take-off and landing (VTOL) uninhabited aerial vehicles (UAV) are frequently used because they offer higher disk loading compared to open rotors and improve propulsive performance. A three-dimensional RANS based computational analysis is implemented for high resolution analysis of these systems under realistic operational conditions. Fan rotor field including secondary flows, tip vortices, blade boundary layers and the wake system is simulated for hover conditions. RANS prediction of hover performance was compared to available wind tunnel test data. Total pressure measurements and computational predictions of mean flow at the fan rotor exit are in very good agreement at hover conditions. The measured and simulated rotor exit field shows a significant level of 3D hub separation affecting the overall performance of the ducted fan. Edgewise flight predictions for the specific ducted fan are in progress.",
