The upper surfaces of the wing are subjected to tension whereas the bottom surfaces need to support the compressive load when the aircraft is in the ground. Loading condition on wing varies during different phases of flight. Each component of the wing serves a different function, need to support various kind of load. Structural members such as spar, rib, stringers are used to carry cantilever load along with aircraft skin.

Full cantilever type wing needs no external bracing but supported internally. The main components of the wing in modern commercial aircraft are spars, stringers, and ribs, control surfaces such as ailerons and flaps fuel tank is also a part of the wing. In some latest passenger aircraft, completely CFRP made wing also available. Magnesium alloy is also occasionally found as the constituents of the wing. In earlier aircraft, wood along with fabric cover was used as the materials to a built wing. Winglets reduce induced drag without a significant increase in horizontal wingspan ( Air Transport Action Group, 2010).ДЄ most common material used for the construction of wing is aluminum. Another innovative idea to reduce fuel burn is to add winglets.

It is possible to take off and land with lower speed in shorter runways with increased wing area but it causes increasing of skin friction drag for the rest of the flight.

Again, using larger wing thickness with thinner skin helps to reduce wing structure weight but resulted in the increased amount of drag especially at the high speeds of cruising flights. Increasing the wingspan can reduce drag but it increases the weight of the wing structure. The efficient wing design is the balancing between different conflicting factors such as wingspan, wing structure weight, wing area, and wing thickness. Proper design of wing is necessary for further aerodynamic improvement in modern aircraft as it was found that reduction of the drag by 1% amount might save up to 4,00000В L of fuel, which reduces emissions by approximately 5000В kg in case of large transport aircraft ( Alessio, 2015). Wing design, shapes, sizes vary depending on the weight, rate of climb, speed and to meet the requirements of flight characteristics for a particular aircraft. Elimination of wires and struts reduces air drag, thus the speed of the modern aircraft is almost double compared to earlier aircraft with the same engine. Modern commercial aircraft are monoplane the wings are fixed, full cantilever type.

On and from the second decade of 20th century, metals were used to construct wing of passenger aircraft. The upper wing and struts are subjected to compressive load whereas the lower wing and wires used to withstand tensile load. The set of wings joined with wires and struts. There were two sets of wings, made of the light wooden frame covered with cloth skin, in the first вЂњheavier than airвЂќ aircraft. The wing is the airfoils, main lifting surfaces, attached to each side of the fuselage to support the aircraft in the air.
