WebIn ducted fans, the stators are used to remove the swirl (or flow rotation) introduced by the fan as it pushes the air through the duct. Removing the swirl improves the fan … WebJan 1, 2002 · Fan noise reduction technologies developed as part of the Advanced Subsonic Technology Program are reviewed. Developments in low-noise fan stage design, swept and leaned outlet guide vanes, active noise control, fan wake management, and scarf inlets are discussed. In each case, a description of the technology is presented and, where available ...
Fenestron - Wikipedia
WebThe SA 340's fenestron was designed by French aerodynamicist Paul Fabre; unusually, this unit had its advancing blade set at the top in defiance of conventional practice, but this was reasoned to pose little impact upon this particular helicopter.

Fan Stator FAQ
WebSep 14, 2024 · $\begingroup$ Please feel free to 'design' each fan independently. 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. Be creative!! $\endgroup$ – WebJun 23, 2016 · The rotor is composed of Bblades and the stator of Vvanes. In order to account for complex blade and vane geometries present in modern turbofan engines, i.e. with stagger, sweep and lean angles varying along the duct height, both the rotor and stator rows are split into annular strips along the span.
