Helicopters generate lift and thrust through the rotation of its main rotor blades. By changing the pitch of the blades, the helicopter can control its altitude, direction, and speed. Additionally, the tail rotor is used to counteract the torque created by the main rotor to keep the helicopter stable.
The tail rotor is essential for maintaining helicopter stability. It counters the torque produced by the main rotor, which would otherwise cause the helicopter to spin in the opposite direction. The tail rotor's perpendicular spin helps balance the torque, allowing the pilot to control the helicopter's direction.
