Improving ducted fan UAV aerody- namics in forward flight [ C ] //46th AIAA Aerospace Science Meeting and Exhibit. Reno: AIAA, 2008: 7- 10.Will Graf, Jonathan Fleming, Wing Ng. Improving ducted fan UAV aerodynamics in forward flight[R]. AIAA 2008--430, 2008....
A ducted fan UAV that can be collapsed into a stowed configuration and then deployed for flight by, for example, inflating the duct to a deployed configuration. The UAV includes a plurality of rotor blades, a plurality of struts and a plurality of control vanes each being pivotally mounted ...
Considering that dynamics of the ducted fan UAV is uncertain, an estimation method of system function based on the smooth saturation function and the state variable integral is proposed. This method has the advantage of less computation while keeping the high estimation performance. The stability ...

The main purpose of the project described in this article was to design a considerably more efficient electrical propulsion system for multi-rotor VTOL UAV units.The first chapter describes the concept of a ducted fan drive for a multi-copter, our experience in propulsion systems design and an ...
In this paper, we address the hover-to-cruise transition control problem for high-speed level flight of a ducted fan UAV. Firstly, the nonlinear aircraft dynamic system is derived and relevant key aerodynamic c...
Ducted-fan drones are expected to become the main drone configuration in the future due to their high efficiency and minimal noise. When drones operate in confined spaces, significant proximity effects may interfere with the aerodynamic performance and pose challenges to flight safety. This study util...
