Design and Analysis of a Liftfan for eVTOL Aircraft

Journal of Turbomachinery
Abstract Ducted liftfans provide greater hovering efficiency to electric vertical take-off and landing aircraft than open propellers of equal disk area. Liftfans are designed with minimized length to limit propulsor weight added and drag incurred during forward flight.
