why airoplane can fly?

Question

it's just has 2

Answer 1

the wings are shaped in an aerofoil shape. this means that as the plane moves forwards the air above the wing moves faster than the air below the wing. This creates a pressure differential (with low pressure above the wing and high pressure below it)

This lifts the wings and in turn the wings lift the fuselage (body of the plane)

Answer 2

The four fources of aerodynamics: Lift, weight, thrust and drag.

For an airplane to fly, it must always engage in a tug of war between the opposing forces of lift versus weight and thrust versus drag.

Think of an airplane moving from right to left and the flow of air moving from left to right. The weight or force due to gravity pulls down on the plane opposing the lift created by air flowing over the wing. Thrust is generated by the propeller and opposes drag caused by air resistance to the airplane. During take off, thrust must be greater than drag and lift must be greater than weight so that the airplane can become airborne.

For landing thrust must be less than drag, and lift must be less than weight.

Answer 3

The air pressure under the wings is greater than above them. This appears only in motion and is due to the wings' profile
If you want to feel this, keep your hand outside from a car or a train in motion, turn it like a wing and feel how the air pushes it upwards and backwards

Answer 4

air flows under and over the wings and as the air goes over the top of the wings it creates a vacume and sucks the plane up and the air flowing underneath acts as a cushon

Answer 5

Because it has a means of propulsion enabling it to achieve a speed through the air sufficient to employ the elements of aerodynamics engineered into its shape and control surfaces.

Answer 6

Airpockets form under the wings of the plane and this is what makes it fly.
