Anti-torque Rotor (Noun)
Meaning
Rotor consisting of a rotating airfoil on the tail of a single-rotor helicopter; keeps the helicopter from spinning in the direction opposite to the rotation of the main rotor.
Classification
Nouns denoting man-made objects.
Examples
- The Fenestron anti-torque rotor design features a ducted fan enclosed in a ring, providing increased safety and reduced noise.
- Single-rotor helicopters rely on an anti-torque rotor to counteract the main rotor's torque and maintain directional control.
- During the helicopter's flight, the anti-torque rotor constantly adjusts its pitch to balance the forces acting on the aircraft.
- In contrast to tail rotors, some helicopters use a NOTAR or Fenestron anti-torque rotor system to eliminate the risk of tail rotor strikes.
- The tail-mounted anti-torque rotor plays a critical role in the stability and maneuverability of a single-rotor helicopter.
