What makes an aeroplane fly?

Question

What makes an aeroplane fly?

Answer 1

The way its wings are built. Air lifts it up as it goes forward.=)

Answer 2

God

Answer 3

Very simple: At sea level, with dead air, there's 14.7 psi of air pressure on everything. If you were to lower that pressure on the top of an object, it would tend to lift. If you lowered it so the total was more than the object weighed, it would rise. The faster air moves, the lower the pressure becomes, so all you have to do is make it go further and therefore faster on top of the wing than the bottom. L= Cl.rho/2.S.V2.  Lift= CofLift x air density/2 x wing area x velocity,squared.

Answer 4

the engine.

Answer 5

I think its cause an airoplane has wings.. like birds can fly with wings.. and fish can fly . wait.. swim with wings or whatever fish have..



you can only fly if you have wings.. I think..

Answer 6

the airplanes forward trust and it's aerodynamic design is what keeping the plane flying. Once if the trust is lost, a plane will slide to a fall whereas a rocket just drops.

So there is only a 'slide' difference between a plane and a missile.

Answer 7

Thrust and Lift

Answer 8

The pilot

Answer 9

The Gravity & the fuel and the pilot and the Wright Brothers & the electronics on the plane.

For the people who gave me the thumbs down. What in blue h**l do you know about planes you Imbecilic b&stards!!

Answer 10

Without lunching into a  boring physics lesson... basically the shape of the wing. Flat on the bottom, bulges at the front on the top.

The air moves faster over the top and causes the wing to want to lift up into the air...

Pretty cool hey!

Answer 11

What makes an aeroplane fly?

Money... LOTS of Money!

Answer 12

Money...

oh yea, and an airfoil (shape of the wings)

lift, Drag, thrust baby!

Answer 13

The aerodynamic shape and the propellers.

Answer 14

Air flow passing over the wing

because of the way its shaped it generates lift.

I could go into more detailed but i cant be bothered

Answer 15

its to do with the air currents on the wings. you need to have a look at 'aerofoils'. Google should help :) or wikipedia.

Answer 16

The cross section (if you were looking right through the wing) looks like a bent teardrop. The front, or leading edge, is a little below the centerline of the wing.  The back edge is also.

The lift generated by the wings is what gets it off the ground.  It works exactly the way a sail helps a sailboat move "upwind".  The wind on the outside of the sail (or on the top of the wing) is moving faster than the wind on the inside of the sail (or the bottom of the wing) This generates lift, in both cases, and moves the boat "against" the wind, and the plane up into the air.

When the plane is taking off or landing, it needs extra lift to break the pull of gravity, so flaps are extended behind the wing to force the air to travel farther over the top, creating more lift,

The more power the plane has, the smaller the wing section can be, and the higher and faster the plane can fly.

Answer 17

its engines and aerodynamic design allows it to fly. The wings and tail has a major part in aeroplane to fly and maneovour in the sky.

Answer 18

Believe me --its Engine.

For take Off. though it can glide for some time for crash landing if engine fails.

Answer 19

hahahahah all wrong answer's for the most part. Let's start with the basics. Ever herd of the four force's of flight? Thrust, lift,drag,and weight.

Bernoulli's principle states that for a fluid, an increase in the speed of the fluid occurs simultaneously with a decrease in pressure or a decrease in the fluid's gravitational potential energy.

That's the basics put in a easier way.

Answer 20

When an object moves through air real fast, the air interacts with the object in a manner like water interacts with your hand when you move your hand through water.  The density of air is less than the density of water, so objects need to travel through air faster to be affected by the air than objects that travel through water.

If you open you hand to simulate a flat surface like an airplane wing, then pull your hand through water real fast, you will notice that your hand will want to move in the direction along which the flat surface of your hand lies.  An airplane wing, at fast speed, responds to air just like your flattened hand responds when moving it quickly through water.  Jet engines, or propellers driven by gasoline engines, pull the plane through the water just as propellers or jet engines pull boats through water.  Moving the fins of the wings and tails on airplanes can change the direction that the airplanes travel.

At fast speeds, airplanes respond to air like solid objects respond to water at lower speeds.

Answer 21

Its the aerodynamics of the wings make the aeroplane fly.See the 'aero' connection there.Obviously pilot has to help its way through the dynamics.

Answer 22

aeroplane is a good song by the chilli peppers... you mean airplane...

The aerodynamic shape of the wings produce a high pressure under the wing and a low pressure above the wing, thereby producing lift.

Answer 23

Engines moves the aircraft forward, air passes by the wings.  The air rushing around the wing crates zones of low pressure and high pressures.  That gives what is call Lift.  If you want to visualize it.  Is like the aircraft Surfs in the air like a Surfer does with its board on the water.  Think of the water as the high pressure part and the top where his feet are the low pressure.  The faster it goes the more sticks out of the water.

Maybe a crude way, but since you can not see air, is the best I came up to illustrate it. I hope it helps.

Answer 24

The shape of the wing.

Air going over the wing has to take a longer trip over the hump on top.  So it stretches out more.

The stretched out air on top has less pressure.  SO the higher pressure air underneath pushes the wing up.

The propeller works sorta the same way.

Add in some bendy bits on the wings and tail and then you can steer where the air goes to make the plane go where you want it to.

Where do you want the plane to go?

Answer 25

Jet fuel and ofcourse the pilot

Answer 26

It's engine

Answer 27

this is based on aeronoutics based upon the bernoulis theorem areoplanes can fly.Pressure on up side and low side of the wings is to be balanced and so that they r flying

Answer 28

Flying of aeroplane is based on the principle of BERNOULI'S THEORM.

Answer 29

Thrust and inertia overcoming gravity.

Answer 30

aerodynamics :)
