AIRCRAFT FLAP'S

 A flap is a high lift device used to reduce the stalling speed of an aircraft wing at a given weight. Flaps are usually mounted on the wing trailing edges of a fixed-wing aircraft. Flaps are used to reduce the take-off distance and the landing distance. Flaps also cause an increase in drag so they are retracted when not needed.

Aircraft flaps essentially aid in the current phase of your flight because they help the wing of the plane adapt to that phase so that it is more successful.

With aircraft flap you can reduce the roll of taking-off and landing.produce more lift so you can lower your take-off and landing speed

               TYPES OF AIRCRAFT FLAP'S

 

1. Plain Flaps

Hinged to the back of the aircraft’s wing, plain flaps pivot down when they are extended. They are somewhat limited in the amount of lift they can create because air can lose energy and start to separate from the wing whenever air moves over the wing.

2. Split Flaps

Split flaps deflect from the wing’s lower surface and produce a little more lift than plain flaps, but like plain flaps, they also produce quite a bit of drag.

3. Slotted Flaps

With slotted flaps, the higher air found below the wings flows upward and the boundary layer is energized, and this is one of the main reasons that the air flow separation is not as severe as it is in other types of aircraft flaps. 

4. Fowler Flaps

As Fowler flaps extend more and more, they move more in a downward motion to create a little more lift, but a lot more drag, which is useful in many circumstances.

5. Krueger Flaps

In addition to the four main aircraft flap types, there are other types as well. The Krueger flaps, for instance, differ from other types because instead of being found on the trailing edge of the aircraft, they are found on the plane’s leading edge.

An example of Krueger flaps can be found on the Boeing 727, which uses inboard Krueger flaps and standard outboard slats.

6. Zap Flaps

Invented by Edward Zaparka in the early 1930s, these types of flaps weren’t used often with the exception of the Northrop P-61 Black Widow, the first wartime plane used in night fighting.

Zap flaps increase the effective wing area and provide both a higher maximum lift and higher drag capacity, especially when compared to split or other types of flaps

7 Junkers Flaps

The Junkers flaps are aircraft flap types that are essentially a slotted plain flap that is fixed right below the wing’s trailing edge and which rotates about its forward edge.

It is a mechanically simple flap and was invented in the late 1920s by Otto Mader Junkers, who wanted a plane with decreased takeoff and landing distance, as well as increased roll response while the plane was in flight.
