Stator design in ducted fan
WebFeb 25, 2024 · The design procedure aims to improve the blade geometry for reducing the losses due to swirls and vortex thus increasing the overall efficiency of the Fan. The design procedure follows an inverse method where in the air foil sections are derived from the mean-line profiles. WebFeb 22, 2024 · Unlike a rocket engine, a ducted fan must first do work on the onflow, and the slower the onflow, the more work must be done on it. Of course the onflow in a static test is sped up before it reaches the inlet, but in flight with a faster moving onflow less work is needed to speed it up and the result is greater thrust when in flight.

http://www.ilgfan.com/Archives/ilghistory.pdf In aeronautics, a ducted fan is a thrust-generating mechanical fan or propeller mounted within a cylindrical duct or shroud. Other terms include ducted propeller or shrouded propeller. When used in vertical takeoff and landing (VTOL) applications it is also known as a shrouded rotor. Ducted fans are used for propulsion or direct lift in many types of vehicle inclu…

WebOct 28, 2024 · Abstract. Electric ducted fan has newly emerged as the most compact type of propulsion fan for flying cars, because of its flexible configuration arrangement, low noise level and high safety level operation. Typically, an electric ducted fan is composed of a hub-driven fan and a hub-mounted inner rotor electrical machine.

Include a stator, etc. The inlet duct would probably be ~30% smaller in diameter, at the throat, than the first fan. The exhaust would also have a diameter, at the throat, about 20-30% smaller than the 2nd fan diameter.
