how does an aero plane fly?

Answer 1

There are four forces--lift, gravity, drag and thrust.

Lift is provided by air passing over the wings. Gravity is a constant, and you know what that is. Thrust is provided by the engine pushing the plane forward and drag is from wind resistance. When lift and gravity balance out, and thrust and drag balance out, you are flying!

The wing is a special shape called an 'airfoil'. The top of the wing is curved while the bottom is flat. This means that air moves faster over the top than under the bottom. And something called the Bernouli effect says that air moving faster has less pressure. The difference in pressure pulls the wing upward, providing lift. The blades of the propellor are also airfoils, pulling the plane forward, providing thrust.

Answer 2

notice the shape of the wing if you look at it from the very end? the bottom of the wing is flat, while the top is more rounded. As the plane moves forward, air flows over and under the wing. But, the air flowing over the wing must flow up and over the rounded part, while the wind under the wing only flows straight, the wind passing over the upper part of the wing creates "lift" causing the plane to rise. That's it in the simplest form.

Answer 3

the engines on the side of the wings suck in air really fast to help to plane go fast. and the wings are shaped in a way to give the airplane lift.

Answer 4

the thrust from the plane taking off creates lift which is greater than the gravity.
