Cirrus Posted December 31, 2008 Report Share Posted December 31, 2008 Does anyone know if the Fenestron is susceptible to LTE? Quote Link to comment Share on other sites More sharing options...
teabagger Posted December 31, 2008 Report Share Posted December 31, 2008 Would that not be LFE? Quote Link to comment Share on other sites More sharing options...
widgeon Posted December 31, 2008 Report Share Posted December 31, 2008 the gazelle I have heard could run out of peddle. And to stir up a hornets nest I had heard that LTE was essentially a Bell problem. http://www.pprune.org/rotorheads/330104-ec...-authority.html For a discussion on another board Quote Link to comment Share on other sites More sharing options...

Phil Croucher Posted December 31, 2008 Report Share Posted December 31, 2008 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.

Cole Posted December 31, 2008 Report Share Posted December 31, 2008 I remember seeing a pretty impressive video a couple years ago of an aircrane in LTE... talk about pucker factor. Quote Link to comment Share on other sites More sharing options...

widgeon Posted December 31, 2008 Report Share Posted December 31, 2008 I assume you do not mean this one ?. Water and fenestrons do not mix too well. Quote Link to comment Share on other sites More sharing options...
Cirrus Posted December 31, 2008 Author Report Share Posted December 31, 2008 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?
