WING CONTRUCTION&THEIR COMPONENTS

Skin:
  The outer surface of the wing.  Originally made of fabric, modern aircraft use aluminum or composite materials due to their lightweight and rust-resistant properties.
Ribs & Stringers:
These make up the inner skeleton of the wing, providing rigidity and strength.  While strength is necessary, it is also important that the wing can flex slightly while it flies.  This flexibility allows it to absorb the stress caused by turbulence and hard landings. Spar:
The main center beam of the wing, designed to carry the structural loads and transfer them by attachment to the fuselage, or body of the aircraft.
Root:
  The wing root is the portion of the wing that attaches to the fuselage, or body of the aircraft.
Wing Tip:
The wing tip is furthest from the fuselage and is typically where the navigation lights are mounted (a red light on the left, a green light on the right).
Slats: Another “high lift” device typically found on swept or delta wing aircraft.  Slats are similar to the flaps except they are mounted on the leading edge of the wing.  They also assist in changing the camber to improve lifting ability at slower speeds.
Fuel Tank:
       commonly located in the wing, fuel can either be housed in its own tank or allowed to fill the cavities between the ribs. In addition to powering the engines, the fuel adds rigidity to the wing
Flaps:
          Flaps are a “high lift/high drag” device. Not only do they improve the lifting ability of the wing at slower speeds by changing the camber,or curvature of the wing, they also create more drag,meaning an aircraft can descend,or lose altitude faster,without gaining airspeed in the process.
AILERON:
Either of two movable flaps on thewings of an airplane that can be used to control the plane’s rolling and banking movements.
To bank to the left, a pilot
must raise the left aileron
and lower the right aileron.
