The tail rotor is a crucial component of a helicopter's design, located at the rear of the aircraft. Its primary function is to counteract the torque produced by the main rotor, which causes the helicopter to spin in the opposite direction. By generating thrust in the opposite direction, the tail rotor helps maintain stability and control during flight. In addition to stabilizing the helicopter, the tail rotor also allows for directional control. By varying the pitch of the tail rotor blades, pilots can steer the helicopter left or right. This capability is essential for maneuvering and navigating in various flight conditions, making the tail rotor a vital part of helicopter operation.
