What is the main advantage of Notor over traditional tail rotor configuration?
Benefits of the NOTAR system include increased safety (the tail rotor being vulnerable), and greatly reduced external noise as tail rotors on helicopters produce a lot of noise.
How much power does a tail rotor use?
On most helicopters the tail boom is a bit longer than the radius of the main rotor, so the force might be 20-50\% lower. On the other hand, the tail rotor is often less efficient, especially on some newer models with small, ducted fans, so the tail rotor might consume a bit more than 10\% of the power.
How can I increase my helicopter speed?
To reach the desired speed:
- From a straight and level flight, push forward the collective slowly and smoothly → The speed increases.
- As the cyclic is pushed forward, the altitude decreases → Raise up the collective.
- Anticipate the moment where the helicopter will reach the desired speed by checking the speed indicator.

What is the most popular rotor arrangement for a helicopter?
Igor Sikorsky seems to be the first to settle on using a single rotor mounted at the rear of the helicopter as a way to counter the torque. This is the most popular arrangement today. Sikorsky actually experimented with many different arragements before selecting a single tail mounted rotor.
Why does a tail rotor give a helicopter lift?
Tail Rotor Translational Lift Just as a main rotor produces more lift when it moves into clean air, a tail rotor develops extra thrust when the helicopter moves it into clean air. Unfortunately, the pilot sees this as a change in anti-torque force which results in an uncommanded yaw of the aircraft.
Do tail rotors consume a lot of engine power?
As a rule of thumb, tail rotors consume up to 30\% of the engine power. Another probem is that due to size and weight constraints, tail rotors are fairly delicate compared to main rotors. This means that they cannot survive an encounter with very large obstacles.
What are some examples of tandem rotors used in helicopters?
Examples are the Boeing-Vertol tandem rotor helicopterswhich evolved from Frank Piaseki’s designs, Charles Kaman’s intermeshing rotor system, and the Russian co-axial helicopter (Hocum or Havoc I think it is, I’ll have to look up the correct name I’m afraid). The V22 tilt-rotor uses counter-rotating proprotors in order to cancel out torque.
