Answer

To get enough thrust to have lot of wind move under the wings to have the wind lift it up...if you went backwards then the balance of the plane would make it impossible to pilot.

What helps an airplane achieve flight by causing the airplane to move faster through the air?

What is the shape of an airplane and why does this have this shape?

The commonly used fuselage shape allows the aeroplane to move forward through the air at a reduced drag. And the sectional shape of the wings create lift.


What forward movement force of airplane provided by engines causes air to move over and under wings?

thrust


What forward movement force of airplace provided by engines causes air to move over and under wings?

Thrust is the forward movement of an airplane that is provided by the engines. The thrust causes air to move over and under the wings and allows the plane to fly.


What holds the airplane in space?

Well the plane is flying through the air not through space. It is the pressure differential on the airfoils that make the plane move through the air.


How does a eagle move?

An eagle uses its wings to move and fly as most birds do. The wings move up and down in order for air to flow through them and allow the eagle to move forward through the air.


Does the air above the airplane move faster than the air below the airplane?

That's true for the airplane's wings, when the airplane is flying upright.


What does a propeller do on a turboprop airplane engine?

The propeller on a turboprop airplane engine spins to move the aircraft through the air. It acts in a way similar to that of the blade in a fan.


How does airplane works?

As an airplane moves forward a vacuum forms on top of the wing. That vacuum lifts the airplane off the ground and into the air.


How airplane suspended in mid air?

Airplanes are NOT "suspended in mid air" - they move through the air and are supported by 'lift' derived from the differential air pressure above and below their wings.


What forces acts on a plane?

Forces that act on an airplane? There are several. First, the thrust of the engines which push the airplane forward. If it's a jet-powered airplane, then the force of the air and burned fuel being pushed out of the BACK of the engine drive the plane FORWARD. If it's a propeller-powered plane, then the propellers spin around in the air and generate lift which pulls the plane forward. There's the force of gravity, which pulls the airplane to the ground. There is the force of "lift". As the plane moves through the air, the air standing still flows backwards over the wing and under the wing. The air going over the wing is forced to move faster than the air moving under, which generates lift. The faster the airplane, or the more curved the wing is, the more lift is generated. The lift generated by the air flowing across the wing lifts the airplane against gravity. Finally, drag tends to slow the airplane down. When the airplane slows down, it generates less lift, and it decends. If it slows down too much, the airplane will stop flying and will crash.


How is a boomerang different from an airplane propeller?

A boomerang is a angled or bent stick that when thrown in the air comes back to the thrower when it does not hit an object. A propeller is a straight crafted out stick that when attached to the engine makes the airplane move forward.
