Do you have tail rotor balancing video of ec 135 fenestron tail rotor?thanks.keep it up on your helicopter videos, educational to those who wants to learn more about this type helicopter.
Not an aircraft mech but I have just noticed that the blades are not evenly spaced, please would you explain WHY? Is it a balance thing or an air vectoring requirement through those stater vanes?? I am very surprised by this. Always thought it was an optical Illusion when I saw these types of rear rotator fans. Regards from South Africa
The uneven spacing of the blades reduces the amount of noise coming from the tail rotor. On the Dauphin (AS 365) helicopters, the blades are evenly spaced (that’s my understanding), and they are very noisy. Hope this helps. Regards.
That is what the company I work for is currently doing. It takes less time to just replace with an inspected unit than it would to remove and inspect then reinstall.
@Gadget0343 I don’t know off hand. Main rotor is around 406. The tail rotor is around 2300, but that’s pulling numbers out of the air, I’d have to look it up.
Hello, I am currently working on a project aiming at the 3D modeling of the Fenestron of the EC135 aircraft (for a school project), I would like to know if you would be able to exchange with me and if possible to provide me some documents (to help me in my modeling and animation approach)? Sincerely and have a nice day,
Hello, I would like to help you but I am pretty sure the information you need is proprietary or export controlled. The documents that I think you are looking for are not mine to share, I’m sorry. You could reach out to Airbus Helicopters, and see if they will give you access to their manuals. Good luck. I would start here airbusworld.helicopters.airbus.com/web/guest/home#/home Your project sounds cool.
These videos are gold
Thank you.
Excellent video and info! Don't work on them but love the way the fenestron sounds!
Thank you for the kind words.
02:41 The asymmetrical arrangement of the blades is very interesting. Regards from Brazil.
Apparently that design reduces noise.
Amazing work. I Thank you for that from Portugal
Much appreciated! Thanks for the kind words.

No not yet, I need to go through a tail rotor balance again. But I plan on making a tail rotor balance video in the future

@@HelicopterMaintenance Many thanks for your reply and information. A really interesting piece of mechanical science.

So, when it is due for inspection, you replace it with a used unit that has been inspected by someone else. Is that correct?

I have always wondered, if you know, what is the ratio between the finestron and main rotor?
@Gadget0343 I don’t know off hand. Main rotor is around 406. The tail rotor is around 2300, but that’s pulling numbers out of the air, I’d have to look it up.

Thanks! That thing looks like is spinning much faster.
@Gadget0343 it’s crazy right. Even a conventional tail rotor, spins so fast it’s invisible.

dude sounds like kevin bacon
Ha! You think?
@@HelicopterMaintenance your voice a little deeper
Nice! Thanks
Show.
Super!

What’s that buddy? I’m not sure what you mean.
