How is it possible,that aero-plains stay in the air?

Question

I mean, how can it fly, if it is so heavy? how can it stay above the ground? i dont get it. it is so heavy, and also when it has people inside,it is even heavier and it still flies. thats super,no?

yes i do,airplanes.thank you.

Answer 1

Come on JetDoc, this is obviously being ask by some one very young, at least refer him/her to a web site.

Answer 2

Hello,
an airplane can fly in simple terms because of it's wings that provide lift. The lift is provided because of the wings being curve This shape creates a specific flow around the wings so that the pressure under the wings is higher than the pressure over the wing. That was as simply explained as i could.

ps. Dean K the air speed over the wing is faster and as it is faster the pressure drops.

Answer 3

The "camber" of the wing, is curved on the top and flat on the bottom. this means that when air travels over the op that is curved it has to travel fast than the air traveling straight on the bottom of the wing.....this creates a low pressure on top of the wing due to the faster air movement and therefore less molecular count. The low pressure on top of the wing and resulting high pressure under the wing pull/push the wings and thus the aircraft into the air. This is a basic version of how they fly.

Answer 4

Hey there the air that passes over the top of the wing creates a vacuum because it travels slower over the curved top surface and faster under the bottom which is usually a flat surface unless it is a fully symmetrical wing witch is curved on both sides witch will make it fly faster

Answer 5

The speed of the plane ("thrust') combined with the shape of the wings (called, "aerofoils") and shape of the plane create an upward thrust when lighter air presure moves over the wing and the heavier air pressure passes beneath it thereby creating "lift". "Drag" is minimized by the round (aerodynamic) shape of the plane's fuselage. The upright wing ("stabilizer") on the back of the fuselage stabilizes the plane and keeps it from spinning around during flight.

Answer 6

As an airplane owner, I can tell you that airplanes need two things to fly: money and lift (in that order)! In the case of some of the airplanes at my old flight school, they were so ugly that the earth just repelled them! If you want a real answer go to www.howstuffworks.com and look at airfoils.

Answer 7

Beleve it or not, it cuz the wings and the air going over it. If y ou dont beleve me, get a paper towel, put it under your mouth, and blow. It makes it go up since there is less concentration above. This is similar owls and other birds

Answer 8

The air moves faster under the wing than over it (caused by the curve of the wing). This "drag" of the air creates lift :)

Answer 9

You're absolutely right! Airplanes are too heavy to fly. It's all a figment of someone's imagination. They aren't real. No one has ever got off the ground in one!

Answer 10

It has something to do with physics and high pressure and low pressures. The low pressure on the top of the wing, causes lift and then the plane flies. good luck.
