What is that thing that makes a plane fly in the sky, especially while takeing off?

Question

What is that thing? Engien- if so, then what is important thing in the engine? How come a huge plane carries tons of loads and fly in the sky? Can you reccomend me some sites?

Answer 1

It's a combination of the engine and the wings. The engine produces the thrust which pushes the plane forward, and the wings provide the lift by moving the ait at different speeds above and below them.

The site I listed will give you a good start in your research.

Answer 2

The term that you're looking for, it is Lift. Lift is the force that carries the plane and makes it able to fly. There are four major forces acting on anything flying: Lift, Thrust, Drag, and Weight (Gravity).

Lift is when the air that passes over the top of the wing is faster than the wind passing along the bottom of the wing. As a result, there is less pressure against the top of the wing as opposed to the bottom. This carries the plane upwards because there is less resistance on the top than on the bottom.

Answer 3

The key is the WINGS. The force is called "lift". The shape of the wings cause air above the wings to flow differently from the air below the wings.

The engine is important though, because the plane must be moving a minimum speed in order for there to be enough lift force to counter the weight of the plane.

Answer 4

It is the wing. The wing is shaped sort of like a teardrop, except on the bottom it's flat and on the top it's curved. Air being parted by the wing's leading edge has to move faster over the top of the wing (because a curve is longer than a straight line) than air moving underneath the wing. This causes lift. You probably already experimented with this by sticking your hand out of a car traveling at high speed. When you change the angle of your hand (in a wing that is called the "angle of attack") your hand either goes up or down. This is because of how the air is moving over and under your hand and your hand's angle of attack into the wind.

Answer 5

Aeroplanes work on 2 principles.

1) Propeller Based
2) Jet Engine

both the types work on the principle of Bernoulli's. In rough; Bernoulli's principle says "moving air creates the state of weightless ness". so when the air moves beneath the wings, that creates "lift" which is similar to the state of weightlessness.

Further, the propeller will be pumping the air beneath the wings, plus it'll increase the acceleration by dragging the air.

2) And In case of Jet Engine, the jet engine creates a high pressure jet so it to push to plane in forward direction plus create the lift.

Answer 6

++ It is the differential between a high and low pressure area.
