What is the Contribution of Tail rotor on Helicopter?

Tail Rotor as named its self is placed vertically at the end of the aircraft and it rotates at high RPM. It has two main jobs to carry out

  1. It holds the helicopters Fuselage from skidding off or turning circles continuously and the next one is it governs the control of helicopter’s position when it is in flight. In the absence of Tail Rotor to fly the Helicopter, the Pilot raises the Collective ultimately increases the lift on the Main rotor Blades so the helicopter can hover. But it rises the problem as Main rotor blades rotate anti-clockwise; the Fuselage now starts to rotate clockwise because of torque reaction. This is the due to Newton’s Third law, which says that every action has an equal and opposite reaction. So to prevent the fuselage spinning uncontrollably there has to be Tail rotor to maintain the equilibrium.heli1
  2. Inspite of this, plus we have advantage of tail rotor as we can use it to control the helicopter in yaw, the movement around a vertical axis. It is carried out by altering the pitch angle of the tail rotor blades to be specified by changing a little amount in the degree of force or turning motion which they produce. The mechanism is made by means of pedal not off course rudder pedals. The beauty of pedal designed is if you apply left pedal it turns helicopter and right with right.
