Fenestron Question

Recommended Posts

All helicopters are subject to it, some more than others, and I have a very interesting video of a large Eurocopter fenestron-equipped machine doing its thing in the snow and ending up in the water.

I remember seeing a pretty impressive video a couple years ago of an aircrane in LTE... talk about pucker factor.

I doubt many helicopters mix well with water. I also assume that NOTAR technology would not be susceptible to loosing it's 'Anti-torque effectiveness' due to similar conditions that the Bells suffer from.

 

I guess to rephrase and try an eliminate any question as to what I am asking...

 

Does anyone know if Fenestrons lose their ability to produce thrust due to interference from MR tip vorticies or 'fenestron VRS' as in "uncommanded left yaw' due to air re-circulating through the fenestron.

 

I personally would think that the size of the shroud surrounding the fenestron would eliminate the ability for a lot of the thrust to re-circulate thus eliminating the problem.

 

I'm not talking about a lack of power either.. That would be more like Fenestron settling avec insufficient power.

 

Let's say - An EC120, low altitude, low AUW.

 

Constructive comments?

 

Happy New Year YFF's
