Exploring the Importance of Tail Rotor Assembly in Helicopters

What is the main function of the tail rotor assembly in a helicopter?

1) It controls the pitch of the rotor blades

2) It provides stability to the helicopter

3) It generates thrust for forward motion

4) It helps in controlling the yaw of the helicopter

Final answer:

Answer:

The tail rotor assembly primarily controls the yaw of a helicopter and provides stability by countering the angular momentum of the main rotor blades. However, it does not generate forward thrust.

The tail rotor assembly in a helicopter performs key roles in the control and stability of the aircraft. Its primary function is in controlling the yaw of the helicopter. Yaw, in aviation, refers to the rotation of the aircraft around its vertical axis. Yaw control is important in helping the helicopter to turn left or right.

The tail rotor also provides stability to the helicopter by countering the angular momentum generated by the main rotor blades. This is crucial because, due to the conservation of angular momentum, the body of the helicopter tends to rotate in the opposite direction to the main rotor blades. The thrust provided by the tail rotor counteracts this tendency, thus providing stability.

However, it's important to note that the tail rotor assembly does not generate thrust for forward motion. The forward motion is primarily controlled by the tilt of the main rotor disc and not the tail rotor. Overall, the tail rotor assembly plays a critical role in ensuring both the controllability and stability of a helicopter while in flight.
