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.

Was helicopters used in the malayan conflict?
Yes, helicopters were used in the Malayan conflict. The RAF used large twin rotor helicopters called Belvederes and smaller ones called Whirlwind and Wessex. The British Army had other even smaller ones there.Yes, helicopters were used in the Malayan conflict.

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.
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 do all helicopters have two propellers?
The rear,small propeller is used for steering and attitude. The main rotor gives lift and forward movement.
What is a rotor cup?
A rotor cup is a component used in various types of machinery, particularly in helicopters and some types of aircraft. It serves as the attachment point for rotor blades, allowing them to pivot and rotate around a central hub. The rotor cup is crucial for the aerodynamic performance and stability of the rotor system. Its design ensures that the rotor blades can adjust their pitch and maintain optimal lift and control during flight.

Is there any helicopter without tailrotar?
Most Helicopters have 1 horizontal rotor (for vertical lift) and a "Vertical Tail Rotor" the latter actually steers the helicopter and/or helps keep it straight, or stabilizes it however there are some helicopters that have 2 horizontal rotors which rotate in opposite directions which perform the same task. Because (in normal circumstances) with a single over head rotor, the craft needs the vertical rotor to stop it from spinning round and round out of control. With twin overhead rotors both rotors provide lift and by slowing one (usually the rear one if my memory serves correct) it provides steering control. Also the blades do tilt slightly to assist in steering. The twin Vertical rotor is mostly used in the larger choppers for heavier loads like in the Chinook.
When were helicopters first used by Germans?
The Germans built a few experimental helicopters before WW2, but never put any into production. The first production German helicopter was the MBB 105, about 1966
What is the working principle of helicopter?
Helicopters generate lift and thrust through the rotation of its main rotor blades. By changing the pitch of the blades, the helicopter can control its altitude, direction, and speed. Additionally, the tail rotor is used to counteract the torque created by the main rotor to keep the helicopter stable.
Were helicopters used in World War 1?
Yes, helicopters were used in WW1. Don't be silly, helicopters were invented towards the end of WWII.
What are Huey Helicopters used for?
The military helicopter, also known as the Huey, are used for command and control, transportation, and also assault gunships. These helicopters are the most famous military helicopters.
Where helicopters used in Pearl Harber?
No. Not in WW2. There were no operational helicopters until really after the War.
