Rotation direction of Tail Rotors: merged threads
Hello all,
Here's a nice one:
If you stand infront of the tail rotor of most helicopters it turns in a clockwise direction ( the blade at the bottom moving towards the nose of the helicopter).
Why?
I talked to our magical chief engineer about this and we speculated on a number of theories.
1: Simple Design feature
2: Aerodynamic reasons
3: Centifugal force reasons (gyroscopic procession)
4: That the way the gearbox was made by the manufacturer!
Any body know why? or is it just a design fluke as in 1:
Going further on that theme. Why do some helicopters have left turning rotors and some right? Is there an advantage in one or the other?
