The shape of an airplane's wings is what makes it possible for the airplane to fly. ... That shape makes air flow over the top faster than under the bottom. As a result, less air pressure is on top of the wing. This lower pressure makes the wing, and the airplane it's attached to, move up.

Does the shape of the wing matter?
In general, the operation for which an airplane is designed determines the shape and design of its wings. If the airplane is designed for low-speed flight, a thick airfoil is most efficient, whereas a thin airfoil is more efficient for high-speed flight.
What is the best shape for an airplane wing?
The elliptical wing is aerodynamically most efficient because elliptical spanwise lift distribution induces the lowest possible drag.
Why do plane wings have different shapes?
Wings have different shapes because they're used for different things. Scientists study how the air moves around a wing, and design different wing shapes for different uses. ... Some plane have wings to carry heavy planes over long distances. Some are designed to fly at very fast speeds, or at very high altitudes.
How does the shape of the wing affect the performance of the glider?
In other words, a wing shaped to cause an action on the air, and forcing it downward, provides an equal reaction from the air, forcing the wing upward. If a wing is constructed in such form that it causes a lift force greater than the weight of the glider, the glider flies.
What shape are the wings of an airplane?
An airplane's wing has a very special shape called an airfoil. It looks a bit like a teardrop, curved on top and flat on the bottom.
Why are plane wings bent up?
Whitcomb designed winglets in the 1970s after watching birds curl their wingtip feathers upward for greater lift. ... 'The winglets you can see on many modern aeroplanes reduce these wing tip vortices increasing their efficiency reducing fuel burn.
How does wing length affect flight?
The size and shape of its wings, particularly the main wing, affects its performance. A lightweight plane with large wings glides well but travels slowly, while heavier planes with smaller wings travel more quickly and cover larger distances.
Which wing generates most lift?
Each wing was tested 20 times. It was concluded that Airfoil Three generated the most lift, with an average 72 grams of lift. Airfoil One generated the second most lift with an average of 35 grams.
Why wings are swept back?
Because wings are made as light as possible, they tend to flex under load. This aeroelasticity under aerodynamic load causes the tips to bend upwards in normal flight. Backwards sweep causes the tips to reduce their angle of attack as they bend, reducing their lift and limiting the effect.
How does aerofoil shape affect lift?
An aerodynamic, curved airfoil will turn a flow. ... The airfoil shape and wing size will both affect the amount of lift. The ratio of the wing span to the wing area also affects the amount of lift generated by a wing. Motion: To generate lift, we have to move the object through the air.
Is Delta wing better?
Delta wings are superior only in supersonic flight, and due to their good low speed characteristics they offer the best overall compromise for supersonic aircraft.
Why are longer wings more efficient?
Stability: Long narrow wings give a plane or bird more stability. ... Less fuel consumption: Having less induced drag means there is less fuel consumption for planes and birds (fat consumption) so they can keep their speed for a longer time than short wide-winged fliers.
What factors affect flight?
The four basic forces [Figure 2-3] acting upon an aircraft in flight are lift, weight, thrust, and drag. Lift is a component of the total aerodynamic force on an airfoil and acts perpendicular to the relative wind. Relative wind is the direction of the airflow with respect to an airfoil.
How does an airfoil wing shape affect its stall characteristics?
The boundary layer may also separate from the body, thus creating an effective shape much different from the physical shape of the object. This change in the physical shape of the boundary layer causes a dramatic decrease in lift and an increase in drag. When this happens, the airfoil has stalled.
How does lift affect an airplane?
When an airplane is flying straight and level at a constant speed, the lift it produces balances its weight, and the thrust it produces balances its drag. However, this balance of forces changes as the airplane rises and descends, as it speeds up and slows down, and as it turns.
