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.


How does the lift thrust drag and gravity affect a helicopter?

Thrust from the helicopter's rotor blades generates lift, which enables the helicopter to overcome gravity and stay airborne. Drag acts as a resistance opposing the helicopter's forward movement, requiring additional thrust to maintain speed. Gravity affects the helicopter by constantly pulling it downward, necessitating continuous lift to counteract and remain in the air.


How does a helicopter achieve thrust?

A helicopter achieves thrust through its main rotor blades. The rotation of the blades creates a pressure difference, causing air to move downward and generating lift. By controlling the pitch and speed of the rotor blades, the helicopter can adjust the amount of thrust produced.


How does a helicopter pilot increase the lift?

A helicopter pilot can increase lift by increasing the pitch angle of the main rotor blades or by increasing the collective pitch angle, which changes the angle of attack for all blades simultaneously. This increases the helicopter's vertical thrust and lift.


How does the size of a helicopter blade affect the speed of rotation?

The size of a helicopter blade affects the speed of rotation by determining the amount of lift generated and the amount of drag produced. Larger blades tend to generate more lift but also experience more drag, which can impact the speed of rotation. Adjusting the blade size can help optimize the balance between lift and drag to achieve the desired speed of rotation.

What is the difference between a helicopter creating lift and anairplane creating lift?

the difference between an helicopter creating lift and an airplane creating lift is simple. an airplane creates lift by moving forward and its wing that has an aerofoil shaped will create lift. this gives the lift for the airplane and to fly. for helicopters, instead of the aerofoil is fix like an airplane, the aerofoil wing is rotating and create lift. that is why the helicopter does not need to move forward to gain momentum to create lift. by rotating the aerofoil (the blade) the helicopter can creates enough lift to lift up the helicopter.and that's how it fly..

Why cant a helicopter work on the moon?

A helicopter requires air to generate lift from its rotors. Since the moon has no atmosphere, there is no air for the helicopter to push against and create lift. This makes it impossible for a traditional helicopter to work on the moon.


How much can a helicopter lift?

Does a helicopter produce thrust or lift?

It produces lift and thrust in different ways.
