The wingBy Andreea StancaContentWhat is a wing?The structure of a wingThe components of a wingClassificationConclusionWhat is a wing?The wing is the essential lift generator,and that is why it is the most important part of an airplane.

The structure of a wingThe longitudinal structural members are reprezented by:SPARS STRINGERS

The transversal structural members are reprezented by: RIBS SKIN

A wing spar is a beam with the upper and lower flanges interconnected into a web or a drug struts.The spar vertically transmits the shearing forces to the wing attachments point and receives a bending moment applied to the flanges.Stringers are attached to the wing upper and lower skin to make it stiff and enable it to withstand stresses exerted by vertical forces.Ribs are the basic members used to give the wing section its aerodynamic shape.It is directly to the ribs and via the stringers that the skin is attached.The ribs take the air load and transmit it to the spar.On the whole the wing members form a thin-walled-closed structure consisting of the framework and the skin working side by side.The skins role is to ensure the required strength and rigidity.That is the main reason why the skin,emphenage and the fuselage should be thickened and other members of the airplane structure strengthened.To prevent the wing skin from loosing its stability in the gap between ribs it is strengthened by longitudinal members-stringers.With this object in view, the honeycomb construction and other structures are employed.The components of the wingWingletThe components of the wingWingletAileronThe components of the wingWingletFlapsAileronThe components of the wingWingletFlapsAileronSlatsThe components of the wingWingletFlapsAileronSlatsSpoilerThe ailerons role is to control the aeroplane movement around the longitudinal axis and the high lift devices,movable leading edge,slats and trailing edge flaps and the boundary layer blow-off or suction gear.The leading edge slats are essentially small movable auxiliary airfoils attached to the leading edge of a wing,which,when closed,fall within the original contour of the wing,and ,when opened,form a slot.The air,passing through this slot,flows over the upper surface of the wing,thus blowing off the boundary layer.The slats have been usually used only for enhancing the aeroplane lateral stability when flying at high angles of attack.There exist two types of slats: fixed or movable.The flaps are located on the trailing edge.These high lift devices allow one to enhance the lift coefficient without increasing the attack angle.The simpliest type is a split flap which is actually a part of the lower surface of the airfoil.Another type of flap is the extension flap.This is structurally more complicated than the split flap.

ClassificationAcording to sets of wing ,aircrafts are of three types:

MonoplaneBiplaneTriplane

AA monoplane is a fixed wing aircraft of one main set of wing surface.A biplane is a fixed wing aircraft with two wings stacked one above the other.A triplane is fixed wing aircraft equipped with three vertical stacked wing surfaces.15According to the position of the wing there are also three types:

Low wingMid wingHigh wing

Passenger Aircraft Boeing 767

Military aircraft Hawker Sea Hawk FGA6

Cargo aircraft Lockheed Martin C130-J HerculeConclusionA general conclusion would be the wing is just a streamlined structure attached to the fuselage of the aircraft, BUT in my opinion is more than thatLab workComplete the gaps with the missing words: The wing is the essential .generator.

Answer the following questions: How many types of wings exist according to their position?Which is the English translation for Aripa romboidala?THANK YOUand have a nice flight !
