How can airplanes fly?and dont say because they have wings...there are things that have wings that dont fly?

Answer 1

Honey, other than penguins, museums, renaissance palaces and cathedrals, everything that has wings is capable of flying.

You just received the physical reasons above.

Answer 2

Look up Bernoulli's principle. The top of the wing on an airplane is curved, the bottom is flat. as the wing travels through the air the velocity of the air over the top of the wing increases, causing the pressure to decrease. as a result, the pressure of the air on the underside of the wing is greater than the pressure of the air on top of the wing causing lift. It is also broken down a little further and get's into newtons laws. Also very important in the aerodynamics of lift. http://www.allstar.fiu.edu/aerojava/airflylvl3.htm
Acctually the web site I just listed has a TON of Information and it is all really good. I am a commercial pilot and also an A and P Aircraft Mechanic and I think I"m gonna spend some time on that site reviewing aerodynamics. :) Hope this helps!

Answer 3

There are a lot of myths floating around as to why airplane wings work the way they do.

Some people mention Bernoulli's principle. Unfortunately, Bernoulli's assumes that the fluid (in this case, air) is incompressible. In most flight regimes - even fast moving Cessnas, and at definitely airliner cruise speeds, which usually fall around Mach .75 to .85 - Bernoulli's is no longer applicable, as compressibility effects must be considered at even moderate airspeeds.

Some also suggest that the curve of a wing causes differing flow speeds above and below the wing. This assumes, however, that both flows must meet at the trailing edge at the same velocity; however, there's nothing enforcing this condition. Also, according to this definition, inverted flight would not be possible.

The real answer is actually quite simple. Recall Newton's Third Law: for every action, there's an equal and opposite reaction. Wings work by deflecting the flow of air downwards. The reaction to the air being pushed downwards is that the air pushes the wing upwards.

Answer 4

Lift is produced by the wings and acts in an upward direction. Wings are able to create lift by accelerating air over their top surfaces, which are curved expressly for that purpose. As the oncoming air — called the relative wind — strikes a wing's leading edge, it splits and travels aft until meeting again at the trailing edge. The airfoil's curve guarantees that the air flowing over the top surface travels faster than the air passing beneath the wing. It's this extra speed that creates a zone of low pressure air — suction, if you will — atop the wing. Meanwhile, the air flowing beneath the wing is of relatively higher pressure. And it's this pressure differential that generates the airplane's lift.

Answer 5

Bernouilli's principle says that when a fluid's velocity increases, its pressure is reduced. Air is a fluid.

The air passing under an aircraft wing takes a direct path from front to back, while the air over the curved top takes a longer path and with lower pressure - result: 'lift' is produced on the wind.

Next time you are in a car on the highway, stick your hand outside the window and gradually tilt it from horizontal to a medium angle - you will feel the air lift your hand like a wing.

Answer 6

You have to understand aerodynamics to know how things fly. As I understand it, the air pressure on the bottom of the wing is greater than the air pressure on top. This gives the wing lift.

Answer 7

The wings are airfoils(of something like that) uses Bernoulli's Principal to create different pressures on the top and bottom part of the wing.

Answer 8

The wings provide a downward deflection of the incoming airstream, which provides an upward momentum to the wings and hence the entire aircraft. Some responders will probably cite Bernoulli's principle, but that is not correct.

Answer 9

Listen, just stick your hand out the window of your car and you can make your whole arm fly. Give it a try. It is fun.

Airplanes work the same way. It's like they grew giant hands and stuck them out the window on either side of the airplane body. And up, up and away.

Answer 10

I'll tell you what, it would be very difficult to explain how an airplane flies in the limited space proveded here and think that anyone could understand it. Suffice it to say that the Bernoulli Effect is the short answer. But I will tell you all this: I am currently thanking God that no one here who has offered up their lame answers designs aircraft or teaches anyone how to fly.
