Tail rotor system. The most common is the multi-bladed rotor, the Fenestron from Airbus, the NOTAR from MD helicopters, then the helicopters with no tail rotor, like the chinook. , instead of thrust generated using a tail-rotor, compressed air can be pushed out through slots over the tail boom and is referred to as the NOTAR (“no tail rotor”) concept. Mar 12, 2025 · Tail rotors are generally powered by the same driveshaft as the main rotor, allowing them to sync up. g. Each counteracts the main rotor torque. The tail rotor generates thrust opposing this torque, stabilizing the helicopter and allowing the pilot to control yaw. . They are essentially identical to a main rotor which is mounted sideways and is controllable in collective pitch, but is not capable of cyclic feathering. Alternate mechanisms or arrangments of rotors are possible in order to have trimmed rotorcraft flight. What are the differences, and how do they behave differently? Find out at Pilots Who Ask Why! Jul 2, 2025 · Without a tail rotor, the helicopter’s body would spin uncontrollably. Tail rotors are either built onto the tail in a traditional design, or they are built Tail rotors share many of the aerodynamics of the helicopter main rotor system. The tail rotor is a smaller rotor mounted vertically or near-vertically at the tail of a traditional single-rotor helicopter, where it rotates to generate a propeller -like horizontal thrust in the same direction as the main rotor 's rotation. Oct 10, 2022 · Let’s talk about the conventional tail rotor vs the fenestron. There are four main types of tail rotor or anti-torque systems on today’s helicopters.
