Flaps

Flaps

  •  Flaps are found in the wing of aircraft its class in the secondary flight control. Are exist inboard on the wings trailing edges adjacent to the fuselage of aircraft.
  • Flaps is extended forward and down from the inboard of the wing leading edge. They are lowered to increase the camber of the wing and high lift and control at slow speeds.



  • By flaps aircraft can be landing with slower speeds and shorten the runway required for takeoff and landing.
  • Extending of flaps is variable and the angle they form with the wing can be selected from the cockpit by simple control, flaps can extend up to 45–50° to take the maximum position.
  • Aircraft constructed composite structures specially Flap also function with techniques of the airfoils and control surfaces of aircraft. The skin of aircraft by Aluminum.
Types of flaps:

     Plain flaps:
  • start from trailing edge when the flap is in the retracted position. The airflow be in wing and in the upper and lower surfaces of the flap, by This is can  increases wing camber and provides greater lift for landing or whatever, then make  the trailing edge of the flap and also important the trailing edge of the wing of the aircraft.
    Split-flap:
  •  Exist in under the trailing edge of the wing. Is extend at the leading edge. The upper surface of the wing extends to the trailing edge of the flap., is trailing edge lowers away from the trailing edge of the wing of the aircraft. Airflow share on the top of the wing remains the same and under the wing to increasing lift.
    Fowler flaps:
  • Is effectively increasing the area of the wing of the aircraft. This creates more lift via the increased surface area of the wing camber When stowed, is typically retracts up under the wing trailing edge similar to a split-flap of the wing.
