Tail rotor propulsion

I'm curious as to how tail rotors are fueled, or are they? Is it a direct-drive system from the main engine, or is a separate smaller engine powered by a fuel line, or are there different systems depending upon helicopter type? Perhaps this is too technical a question for this article, but it is the subject which brought me here, and seems appropriate for the topic. sharkface (talk) 21:15, 16 April 2008 (UTC)

I don't know this first hand, but from my general aviation reading over the years, the same transmission that send power to the main rotor splits off some of the power though a drive shaft that runs to the tail rotor. The transmission may combine power from two or more engines, but generally all power from the engines goes to the transmission first, then to the rotors. I'll ask around to some of the pilots and engineers in WP:AIR, and see if they can help add some more explanation to the article, with sources. - BillCJ (talk) 02:04, 17 April 2008 (UTC)

That certainly makes sense about the transmission and drive shaft, but I'm a total neophyte on aviation. Thanks! sharkface (talk) 01:55, 18 April 2008 (UTC)

Usually, helicopter transmissions are not 'direct drive' but are powered by air pressure and turbines. The helicopter's main engine(s) compress air and move it through another turbine, spinning it, and powering the main and tail rotors. I think usually the engine, and main and tail rotors are set to run at the same constant, respective speeds, and flight controls are possible through varying the pitch of the rotors. 75.157.198.121 (talk) 03:07, 14 May 2008 (UTC)

Information?

What has any of this chatter got to do with what a tail rotor is or what it does? —Preceding unsigned comment added by 69.122.62.231 (talk) 19:08, 10 June 2008 (UTC)

Removed paragraph from "New Developments"

I just removed the paragraph below from the New Developments section, as it makes little sense and has been unreferenced since it was added in 2005. If anyone can reword it so that it actually describes New Developments of the tail rotor, rather than a confusing and incorrect explanation of how a tail rotor works, please do.

In some more recent helicopter designs, the tail rotor has been mounted tangential to the furthest back point of the top rotor. That is to say that it looks much like an old propeller plane, only at the back of the helicopter instead of the front of a wing. In these new designs the rotor spins in a direction opposite to the top rotor (i.e. counter-clockwise if the rotor spins clockwise and vise-versa). This in effect, cancels the spin and has the added benefit of producing forward thrust.

Born2flie: Stub-class. I recommend that an article named Antitorque (helicopter) be created and this article, NOTAR, and Fenestron be merged into it. --00:59, 8 January 2007 (UTC)
