How do planes fly?

Question

Like I know they got wings and boosters and engenes, But how do they stay in the air how. How do they fly?

Answer 1

top of wing is longer than bottom...as plane goes forward the air on top must go faster causing low pressure/lift

Answer 2

Cubic currency.

Answer 3

Top of the page, under principles. There are Levels 1 through 3,

depending on the degree of knowledge you wish to explore.

Usually Bernoulli's principle is used to explain lift, which says that if air speeds up the pressure is lowered. Thus a wing generates lift because the air goes faster over the top creating a region of low pressure, and thus lift. This explanation usually satisfies the curious and few challenge the conclusions. Some may wonder why the air goes faster over the top of the wing and this is where the popular explanation of lift falls apart.

If you get to the physical description of lift in level 3, you will find that this principle really doesn't work.

Answer 4

With wings

Answer 5

Put very simply, the wings provide lift. Wings are airfoils. As airfoils move through the air, an area of low pressure (a vacuum) forms above and an area of high pressure forms below. The low pressure lifts just like your vacuum cleaner would lift something off the floor by means of low pressure. Then engines provide thrust that push the aircraft forward so that the wings may move through the air. The tail surfaces are primarily for balance and control.

Helicopters work in the same manner. The rotor is a big revolving wing that moves through the air by means of being turned by the engine.

Answer 6

The basic principles of airplane flight are covered in the sixth (6th) grade in US schools.  Look around for an old 6th grade science textbook.

You can also ask your teacher or spend some time in the library.  Ask the librarian for some information on basic principles of flight.

Answer 7

Very well and frequently, thank you very much.

Answer 8

If you go with the science/math of it, a mathematician named Bernoulli came up with an explanation/ equation that said that the air going over the top of the wing has to move faster to equalize and meet up with the air traveling beneath the wing.  That works fine so long as you're talking about a standard Clark Y airfoil (flat on the bottom, air foil/round on the top/front.  But when you move into symmetrical airfoils like those used in stunt planes, you find his math doesn't add up.  The air on those has to move at equal speeds top and bottom.  So, it becomes a matter of length, width and chord of the "wing" added to speed and angle of attack.

Give me a sheet of plywood and an engine and I can make it fly!
