The tail rotor drive is primarily located on the aft side of the transmission system in helicopters. This position is critical for the functioning of the tail rotor, which counteracts the torque effect produced by the main rotor. By being situated on the aft side, the tail rotor drive effectively transmits power to the tail rotor assembly, enabling it to provide the necessary thrust for directional control and stability during flight. This design is standard across many helicopter models, ensuring efficient performance and control by allowing the tail rotor to counterbalance the torque from the main rotor. The positioning also aids in minimizing the overall structural complexity and weight distribution of the helicopter.
