Helicopters why hasn t NOTAR been more popular
33. NOTAR. No tail rotor use of a ducted fan within the helicopter s body and venting the air through the side of the tail boom to get the desired anti-torque. One big advantage is simplicity and ruggedness no tail rotor to get damaged no tail rotor gearbox or driveshaft to wear and/or malfunction. Another is noise NOTAR is quieter.

The Heart of the Helicopter The Rotor AssemblyHow
Apr 01 2000 · Using this rotor design a pilot can manipulate the swash plate assembly and control the helicopter s motion. With the cyclic the swash plate assembly can change the angle of the blades individually as they revolve. This allows the helicopter to move in any direction around a 360-degree circle including forward backward left and right.
