Fenestron Tail Rotors
There has been some debate in the past about the effectiveness of the fenestron. As I remember, it is a good aviation trade off; less effectiveness but much quieter.
The manufacturers marketing department is always quick to point out the positives and very slow to admit any short comings - obvious!
I have also heard of issues relating to the lack of thrust from the fan in a fenestron in certain conditions. The same could be said of the tail rotor. Are there any instructors out there who have had the brown corduroy trouser syndrome whilst flying a fan tailed helo? Can we perhaps get some input from the pilot of the Durban machine as to what exactly happened?
