The tail rotor is a crucial component of a helicopter that helps control its direction and stability. Located at the rear of the helicopter, it counteracts the torque produced by the main rotor, preventing the helicopter from spinning uncontrollably. By adjusting the pitch of its blades, the tail rotor can change the helicopter's yaw, allowing it to turn left or right. In addition to providing directional control, the tail rotor also contributes to the overall balance of the helicopter during flight. If the tail rotor fails, the helicopter can become difficult to control, making it essential for safe operation. Proper maintenance and functionality of the tail rotor are vital for pilots and the safety of the aircraft.
