Most helicopters fly with only one rotor. If you mean one blade, that is because it would be unbalanced.

What is helicopter rotor and propeller?

The rotor is like the engine to the propeller. A propeller is the fan like blades on the top that spin to make the helicopter fly.


How do helicopters fly without wings?

They derive lift and propulsion from the rotor


Can a helicopter fly on Mars?

No it can not fly on mars because theres no air for it to create lift. Helicoptors can only fly on earth and they cant fly at high altitudes.


How does the helicopter use air to fly?

the main rotor gains lift from the air.


How does the helicopter fly up and down?

The main rotor speed is reduced or increased


What is the most important part of a helicopter?

The most important part of a helicopter is its rotor system, which includes the main rotor and tail rotor. The main rotor generates lift and allows the helicopter to ascend, descend, and maneuver in various directions, while the tail rotor counteracts the torque produced by the main rotor, ensuring stability and control. Together, these components enable the helicopter to fly safely and effectively.


Why does a helicopter fly?

The rotor, shaped like an aeroplane wing, creates lift in the same way. The problem is in maintaining stability, as it will cause the body of the helicopter to rotate, too. That is why most helicopters have a tail rotor, to counter that effect and grant the pilot stability.


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.


How do you give clue for helicopter?

To give a clue for a helicopter, you can mention its ability to fly, its rotor blades, or its use in transportation or rescue operations. For example, you could say, "It can soar through the sky with spinning blades," or "It's a vehicle that can hover and take off vertically."


Can a helicopter take off from the moon?

No, a helicopter cannot take off from the moon because there is no atmosphere on the moon to generate lift for the helicopter's rotor blades. Helicopters require air to push down against to lift off the ground, and since the moon has no atmosphere, a helicopter would not be able to take off.


What is the difference between the way airplane and a helicopter fly?

The basic difference can be boiled down to this: The similarities between the two is that they both fly from air moving over the airfoils. On a plane this is also called the wing, on a helicopter it's called the rotor. Since the airplane is a 'fixed wing' aircraft, the plane must be moving forward in over to fly. On a helicopter the spinning rotor generates lift all the time.
