An aircraft in flight experiences an upward lift force, as well as the thrust of the engine, the force of its own weight, and a drag force. The lift force arises because the speed at which the displaced air moves over the top of the airfoil (and over the top of the attached boundary layer) is greater than the speed at which it moves over the bottom and because the pressure acting on the airfoil from below is therefore greater than the pressure from above,This is how planes get lift.

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 drag increases as lift increase - for helis?

As lift increases for helicopters, the angle of attack of the rotor blades must also increase to generate more lift. This higher angle creates more drag due to increased air resistance and turbulence. Additionally, the higher lift forces can lead to increased induced drag, which is generated as a byproduct of producing lift.


Why does the lift on an airplane wing increase as the speed of the airplane increases?

The lift on an airplane wing increases as the speed of the airplane increases due to the Bernoulli's principle. Faster airspeed over the wing creates lower pressure, and higher pressure underneath the wing generates lift. This relationship creates more lift force as airspeed increases.


An airplane stays in the air because the air pressure on the top of the wing is less than the pressure on the bottom This creates a phenomenon called what?

This phenomenon is called lift. The pressure difference between the top and bottom of the wing creates an upward force that counteracts gravity, allowing the airplane to stay aloft.


How does a rocket use lift and thrust?

Rockets use thrust generated by their engines to push them forward and overcome gravity. They do not rely on lift as traditional airplanes do, as they operate in the vacuum of space. The propulsion from the engines creates the necessary force to lift the rocket off the ground and into space.

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..

What is the difference how a helacopter creates lift and an airplane?

They both utilize airflow over an airfoil. The helicopter moves the airfoil (blade) by spinning them, as air passes around the blade it creates lift. An airplane uses thrust from the engines to push the airfoil (wings) forward through the air, the air then flowing over(lower pressure) and under them (higher pressure) produces lift.


What causes awing to lift?

The aerofoil shape of a wing is designed so that the speed of air flowing above the wing is faster than that below. This creates an upward force, called lift.


Do paper planes fly longer with a wide wingspan?

Sort of a wider wing span creates more lift but also creates more drag the shape of the wing is also a factor


How do aeroplanes fly even though there airfoils cant flap like birds wings?

The different air pressure above and below the wings creates lift and allows the 'plane to fly given enough forward motion.The different air pressure above and below the wings creates lift and allows the 'plane to fly given enough forward motion.


What does the difference in air presssure above and below a birds wing cause?

The difference in air pressure above and below a wing causes lift. The lift creates flight. The result is that birds fly.
