Module 12. Helicopter aerodynamics, structures and systems

How do the rotors turn on a co-axial rotor system?

  • They counter-rotate on a common shaft.
  • Both rotate in the same direction on a common shaft.
  • They counter-rotate on separate shafts.

the correct answer is that generally and not in Kamov in particular as Bruno mentions,is that they counter rotate on seperate shafts.
