For better airflow.
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.
The wing shape of an airplane, particularly its airfoil profile, affects its ability to generate lift. A curved or cambered wing shape helps generate more lift, allowing the airplane to carry more weight. Additionally, the wing design influences the distribution and efficiency of lift across the wingspan.
A wing lifts an airplane off the ground through the Bernoulli's principle, where the shape of the wing creates a pressure difference between the upper and lower surfaces. This pressure difference generates lift, which counteracts the force of gravity and allows the airplane to become airborne.
The air pressure above the wing is lower because the air traveling faster over the curved top surface creates lower pressure compared to the slower-moving air below the wing. This pressure difference generates lift, allowing the airplane to fly.
The aircraft gains speed. Its wing is curved on top and flat on bottom, so it gains lift. Then it soars into the sky with its nose pointing up.
An airplane wing. The top is curved, so the air traveling over the top of the wing needs to travel faster than the air going along the bottom. As the velocity of air increases the pressure decreases.
What wing design for a paper airplane will soar the farthest
The shape of an airplane wing, specifically its curved upper surface and flatter lower surface, creates a pressure difference that generates lift during flight. This pressure difference, known as Bernoulli's principle, causes air to move faster over the top of the wing, creating lower pressure and lifting the aircraft up.
1905 was the first fixed wing airplane
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.
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 best wing shape for sn airplane is like a triangle because it fly straight
