The turning rotor of a helicopter creates lift by pushing air downwards, which generates an upward force that allows the helicopter to move upwards. This lift is created due to the rotor blades producing a pressure difference between the top and bottom surfaces as they rotate through the air. The angle of attack of the rotor blades can be adjusted to control the amount of lift produced and therefore the upward movement of the helicopter.

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.
The main rotor on a helicopter creates what?
The main rotor on a helicopter creates lift, which allows the helicopter to become airborne and maintain its altitude during flight.
Why is it necessary to have the tail rotor on the helicopter that spins perpendicular to the spin of the main rotor?
The tail rotor is essential for maintaining helicopter stability. It counters the torque produced by the main rotor, which would otherwise cause the helicopter to spin in the opposite direction. The tail rotor's perpendicular spin helps balance the torque, allowing the pilot to control the helicopter's direction.
Why don't helicopters spin around in the air?
Helicopters have a tail rotor that counteracts the torque produced by the main rotor, preventing the helicopter from spinning. The tail rotor provides anti-torque to maintain stability and keep the helicopter facing in the desired direction. By adjusting the tail rotor's thrust, the pilot can control the helicopter's orientation.
What is the thing that spins at the top of a helicopter?
The thing that spins at the top of a helicopter is called the rotor blade. It provides the lift necessary for the helicopter to take off and stay in flight. The rotor blades are attached to the main rotor mast and are powered by the engine.
How does the turning of the rotor help the helicopter move upwards?
the wind
What are the major parts of a helicopter?
It's main rotor, tail rotor makes the helicopter to move which is powered by it's engine. These are the major parts of a helicopter
What makes the rotor turn on a helicopter?
The engine turns the rotor through a transmission.
What makes a helicopter move forward?
The main rotor is tilted forward.
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.
Another name for helicopter propelers?
Main rotor and tail rotor. The main rotor is on top of the helicopter consisting of two or more blades, and the tail rotor is at the back of the helicopter, which also consists of two or more blades.
The main rotor on a helicopter creates what?
The main rotor on a helicopter creates lift, which allows the helicopter to become airborne and maintain its altitude during flight.
What is a helicopter with 2 propelers?
That is a twin rotor helicopter
What is on top of a helicopter?
Rotor blades are on top of a helicopter.
What does the tail rotor of a helicopter do?
it stabilises and steers the helicopter.
Where was the helicopter rotor made?
The helicopter was made in China.
What is a blade from a helicopter in words?
The main blade on a helicopter is the 'rotor'
