Is a tail rotor called a tail rotor because it has to be at the back? Would one, hanging from the side, counter-act engine torque just as well?

It wouldn't be aerodynamicaly correct.

did you ever study leverage in school?

If it was on the side of the fuse it wouldn't work nearly as well. The further it is from the center the more leverage it has to counter the torque. At least that's what makes sense intuitively to me.

yes a tail rotor would work if it where in front or on the side. But in foreward flight the tail rotor would naturally want to position itself to the rear of the heli.
fly your heli in fast foreward flight with the gyro in normal mode and see how the tail naturally hangs to the rear and the tail will follow during a turn with little or no rudder input needed.

its just phisics yo

Just fly your heli backwards... tada... the tail rotor is in the front!

Fly your Heli sideways... tadaaa... the tail rotor is on the side!

Of course flying the heli forward results in the best aerodynamics.

Actually, I guess one could call it a side rotor when one is flying sideways or a front rotor when one is flying backwards.

I ask....because of the patent applied for by Eurocopter for it's version of the "compound helicopter." It is supposed to compete with the X22, for the fastest helicopter. It uses wings, with props for forward flight and i would think, torque compensation while in hover mode.

Interesting concept, and caught my eye for cool ness.
If i had a scanner i would putin the pic of what it is supposed to look like. Picture twin engine big plane with rotor on top. and a very funkey flat top T tail.

It won't need a tail rotor then since its main rotors will be counter-rotating thus not creating the torque effect of a single rotor system. That's why V-22's don't need a tail rotor, or Chinook's etc.
