What makes planes fly?

Show all answers

JCV

It's called Bernoulliâ€™s principle. As the plane moves forward, propelled by the engines, air flows over and under the wing. The wing shape is more bowed on top and more flat on the bottom. This makes the air flowing over the wing move faster than the air flowing under the wing in order to reach the same point at the same time. That faster moving air has a lower pressure than the air flowing under it. This pressure difference causes the wing to move towards the area of low pressure: up. This phenomenon is known as lift and this is what makes planes fly.

ANF

The thrust of the engine push it forward and as the air rushes over the top of the wing, which is a special shape, it makes a negative pressure on the wing top and the wing moves into it and thereby lifts the aircraft. The speed of the air over the wing is critical that is why the aircraft needs to taxi very fast into the wind.

the wings and the engine of course.

The shape of the wings and the way air goes along the upper and lower side of wings differently creating different forces (as long as there is also some forward propulsion to activate these forces)

Aviation fuel amongst other things

Planes don't fly, they just go through the air, birds fly however.

If a fish had feathers in place of scales it would fly also. There is an ocean of air above the land and sea, that enables a designed aircraft to skim over the clouds.

engines and money

a lilot a throttle 2 to 4 very large engines thrust and a lot of aero dynemics ie wing technology dont ask about aerodynamics cause i dont know

Momma say it's God's gentle little fingers liftin us all up in the sky like a fluffy little boyd.

Gerbils running on those wire wheels. Hundreds & hundreds of gerbils.

The wing shape. The wing is cambered in a way that the air going over the top of the wing has to go faster then the air going under the wing. This creates low pressure on the top of the wing and higher pressure underneath it producing life, or "sucking" the wing up

chillipope

The shape of the wings, there is more surface area on the bottom of the wing and displacing the force of air keeps it aloft, along with the spread of the wings.

my brother once said it was the three hundred passengers willing it off the ground - and I believe him!

Upside down cats. You know if a cat jumps off something - it always lands on its feet.

Conversely, if you hold a cat upside down you'll find it starts to float up. Strap a bunch of them in a wing and up it goes!

Oh, and before you ask cats do roll on their back with their feet in the air, but their hair acts like velcro on the floor to stop them floating off....

Barbara Doll to you

Nobody knows they just stay up there. It's amazing.

ling l

Gravity.. engine force??
