WHY AN AIRPLAIN CANT GO to the space?

niehc: WHY AN AIRPLAIN CANT GO to the space?
Ive been wondering why an airplain cant flight to the space, what does it need to get there? is because atmospheric pressure? please help me with this!

An aeroplane needs air to attain flight and to keep the engines running.

Not much of that in space so if you attemt to fly a plane to high, the plain will stall and come back down again where there is more air.

The short answer is lift. A space shuttles uses rockets to push itself into space. An airplane on the other hand, uses considerably different and weaker engines to move while relying on the wings to lift it off the ground. Basically, an airplane wing creates a pressure differential, in which the air directly above the wing is at a lower pressure than the air directly below the wing. This causes the air underneath to try and push upwards toward the lower pressure area, in which case it is pushing up against the wing and lifting it up.

At a certain point in the atmosphere, there would not be enough air pressure for this process to continue, and the plane would have reached it’s “ceiling”.

Also, as the above answerer noted (which didn’t occur to me at first), the engines used in airplanes would not be able to function at a certain point.

An aeroplane with jet angines needs air for two things: lift and fuel combustion.

A jet engine works by taking in air, compressing it, then introducing fuel and igniting it to produce thrust. As it climbs higher and higher the air gets thinner until the engine is no longer able to pull in enough air to light the fuel. At that point the engine stops and the plane can’t maintain powered flight to climb any higher.

But more problematic is that the wing uses the air to generate lift by the way the air flows over and under it. As the plane gets higher the air gets thinner until there just isn’t enough of it to produce any lift and the plane cannot climb any higher.

The only way into space is with a rocket that carries its own oxidiser so it can burn fuel at any alititude and doesn’t require wings to get lift.

an airplane simply does not have the power to escape the gravitational pull of the earth. the speed that an object must attain in order to reach the “escape velocity” of the earth is approximately 11.2 kilometers per second.

Answer by callofduty4s
its all about thrust if it doesnt have enough speed about i think 14 thousande kilometers per second+ to reach the escape velocity and if it does reach that if it re enters the atmosphere itll burn up without the special heat tiles

An airplane needs air to fly. Airplane wings have a special shape called an “aerofoil” which is nearly flat below and curved above. When air flows over them fast enough it makes a partial vacuum above and the ordinary air pressure below pushes the wings up. That is called “lift”. There is no air in space, so you can’t get any lift.

Above a certain level there is not enough air to supply enough lift.

Apart from that the engines need air to burn the fuel. You will see that a jet engine has a big air intake on the front to let air in. Just behind that is a big fan which pushes the air into the engine.

In propeller planes the air intake is there too, sometimes you can see an air scoop on the front just behind the propeller.
