Its called an airfoil. Its what gives the plane lift during flight. ------------------------------------------------------------------------------------------- An airfoil is the totality of the wing. There are various designs of airfoils. One such design was of a wedge shape, which is contrary to the accepted design of the curved upper surface. The basic airfoil includes the upper curved surface of the wing, the bottom flat or less curved surface of the wing, the cord thickness and total wing span. I had given a more thorough lay explanation of how lift is produced, but for some reason that explanation was removed. Go figure? My past background is as a flight instructor/mechanic/cropduster pilot.
The top surface of an airplane wing is curved to create lift. Because of the curve, air has to travel farther across the top of the wing than across the bottom; this creates a low-pressure condition that pulls the airplane into it.
Basically they 'curve' the wing, forcing the airflow to lift more weight.
There is a concept of lift when aircraft is built. The wing of an airplane takes a shape commonly referred to as an airfoil, that is curved downward on the top, but is mostly flat on the bottom. When an airplane speeds down the run way, the air is "split" by the wind. Air that travels above the wing is fast (since it has a longer distance to travel due to the curve) and is low in pressure. Air that skims the bottom of the wing is relatively slower (since it has a shorter distance to travel, because it is flat) and has higher pressure. Since there is more pressure below the wing than there is on top, the airplane is lifted up.
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.
The air on top of the wing is at a lower pressure than the air at the bottom of the wing so wing is pulled upwards
Low pressure is created over the top of the wing while higher pressure is below the wing which generates lift.
There is more pressure under the wing than is on top of the wing. This is what generates the lift for flight.
Bernoulli's Principal is as the speed of a fluid (liquid or gad) increases the pressure of the fluid decreases. The shape of an airplane wing causes the air to move faster over the top of the wing, thus lifting the wing up. Bernoulli's Principal states that fluids flow faster when compressed, therefore a wing( which is curve on top and straight on the bottom) which forces air on top to flow faster due to the curvature decreases the pressure on the top of the wing, thus creating lift.
differential in wind speed over the wings produces high pressure under the wing and low pressure on top of the wing.
Airplane wings are shaped such that the length of a path from the leading edge of a wing to the trailing edge is longer when going over the top than across the bottom. For this reason, air going over the wing must travel faster than air traveling beneath the wing.
Winglift.Lift is pressure on the wing due differential air pressure below and above wing. This difference results from the difference in curvature of the wing top and bottom..
I'm assuming you want to know how it flies.The engine(s) get the airplane moving forward and get the air running over the wings. The wing of an airplane is shaped so that the air splits. The air over the top of the wing is going faster than the air below the wing. Following Bernoulli's Principle, the pressure of that air is lower. The higher pressure below the wing pushes the wing (and the airplane attached to the wing), upwards. That is a simple explanation. Find an airplane site to get a detailed explanation.the wings lift the plane and the speed helps it lift if it does not go fast enough it wont fly
