Ducted propeller
-
The aim of this research is to employ a sensitivity study for the total thrust of a ducted twin counter-rotating propeller system design for UAV applications using computational fluid dynamics (CFD). Two factors were investigated: propeller spacing and difference between blades pitch angle. Using discrete values for both factors, 32 designs were analysed and evaluated. The same approach was also used for an equivalent unducted propeller system to access the influence of the duct.

This paper will use computational fluid dynamics (CFD) to investigate the effects of a shroud to the thrust and power of a 9.5-inch rotor and 15-inch rotor. The results show that at the same rpm, a shrouded rotor can produce 20% more thrust than a free rotor.

This paper proposes to design the ducted-fan singlecopter, a new kind of vertical take off and landing (VTOL) device with promising applications. As its most basic level, the singlecopter is a device features a single propeller that produces thrust and a set of four wings to control navigation and flight maneuvers.

The results obtained will be compared with the manufacturer's results (conducted by the University of Illinois, without duct, in static condition), and compared to the numerical simulation results. From there, choose the kind of propeller that match the design of the UAV.
