Why is a single rotor never used?

It would defy the physics that helicopters already fight to stay airborne.

Example. The small weights on the rim of your car. You lose one 10gram weight and you can already feel the difference of the weight on the wheel. Apply it to a helicopter. One blade weighing about 70kg spinning around the central point.

however it is possible, igor sikorsky's first heli had only 1 blade... you try to swim with 1 hand possible but unstble

The MD 520N helicopter doesn't have a tail rotor. They direct the jet blast from the engine through a vent in the tip of the tailboom.

As to the above...the er seems to be confusing "rotor disc" with "rotor blade." Some helicopters CAN fly on one rotor blade. I was at the fire station at Campbell Army Airfield at Ft. Campbell, KY, in 1983 getting some fire extinguishers recharged, when all of a sudden the whole station cleared out to go to an incident. A CH-47C Chinook helicopter had lost two of the three blades on its rear rotor. It landed safely--very tail-low, but safely--but I can only imagine the pilot fought that aircraft the entire way back to the airfield. A Blackhawk, which has one main rotor (Chinooks have two), would have crashed under similar circumstances because he wouldn't have had enough lift to stay in the air.

Why is a single rotor never used on helicopters?

In helicopter terms, the Rotor is actually the set of blades as a whole, individual blades are termed to be the rotor blades. So if you negate the Chinook, and a few other unusual types of helicopter, all helicopters utilise a single rotor. If you mean a single rotor blade, well again a single rotor blade design has been used on a helicopter.... An example of this was the Hiller HJ-1 Hornet, also the Boelkow 101/103 are good examples of this design.


Some helicopters have on rotor on a horizontal axis perpendicular to the helicopter body at the tail Why is a single rotor never used?

because the spinning motion of the main rotor crates a force called torque, with makes the helicopter's body want to spin in the opposite direction. The tail rotor is used to create anti-torque and stop the body from spinning. In the cockpit, the pilot will use anti-torque pedals which change the angle that the tail-rotor's are spinning at. Allowing the body to spin slightly means it can change direction, and forcing it to spin more in the opposite direction allows it to turn (or yaw) the other way. A single rotor helicopter will spin uncontrollably in the air and will possibly not take off at all.

Why did rotor use a single character in zita?

Rotor used a single character, Zita, to represent the common woman's perspective and experiences during the Ethiopian revolution. This allowed him to explore themes of power, oppression, and resilience through a personal and relatable lens. By focusing on Zita's story, Rotor was able to create a more intimate and impactful narrative.

What is a back rotor of a helicopter used for?

it depends. sometimes they make the helicopter turn. On models when they are facing up like the main rotor, they propell it forward so the gyro can fall to one side and lean the chopper forward. The major purpose of the back rotor is to counteract the torque of the main rotor. On helicopters with a single top rotor, if there were no back rotor, the torque would cause the helicopter to spin around as soon as it lifted off the ground.


Why does a typical small helicopter with a single rotor have a second small rotor on its tail?

The small rotor on the tail, called the tail rotor, counteracts the torque produced by the main rotor of the helicopter. Without the tail rotor, the helicopter would spin uncontrollably in the opposite direction of the main rotor. The tail rotor helps maintain the helicopter's balance and heading.


Why running helicopter backside fanmotor?

If you are talking about the rear rotor (in the very back); it is used to counter the turning or yaw of the aircraft. The main rotor is turning in a certain direction and the rear rotor keeps the copter from just spinning around. The rear rotor can be adjusted to make the copter slowly turn.
