Flaps Meaning, Synonyms, Antonyms, Translation, and Use Cases

Flaps

Have you ever heard of the word Flaps? If not, In today’s Word for the day, we will look at the Flaps, its meaning, synonyms, antonyms, translations, and use cases.

Beyond that, we will look at what Flaps means both in Aviation, and their types.

Meaning

Flaps are a high-lift device used to lower an aircraft wing’s stalling speed at a specific weight. In a fixed-wing aircraft, it is typically positioned on the trailing edges of the wings.

It is used to shorten the distances required for takeoff and landing. When not required, flaps are retracted since they increase drag.

Most aircraft have partial-span flaps fitted, which run span-wise from close to the wing root to the inboard end of the ailerons.

A decrease in the angle of attack on the outboard half of the wing coincides with a fall in the percentage of lift provided by that region. This is helpful because it widens the outboard half’s margin above stall, keeping aileron effectiveness and lowering the possibility of an asymmetric stall and spinning.

They are a high lift device on the wing’s trailing edge. They increase the chamber, chord, and, in most instances, the surface area of the wing when stretched, which increases lift and drag while decreasing stall speed. The performance takeoff and landing are enhanced because of these elements.

They come in a vast variety of designs, and which one is best for an aircraft will depend on its size, speed, complexity, and other characteristics, as well as the time during which it was built.

 

The most typical flaps are:

Flat flap

The rear part of the aerodynamic profile of the wing pivots downwards on a simple hinge mounted on the front of the flap.

Split flap

The rear part of the lower surface of the wing is hinged down from the leading edge of the flap, while the upper surface remains stationary.

Slotted Flap

Comparable to a Plain Flap but incorporates a gap between the flap and the wing to force high pressure air from below the wing over the upper surface of the flap. This helps reduce boundary layer separation and allows the airflow over the flap to remain laminar.

Fowler Flap

It slides rearwards level for a distance prior hinging downwards. It first increases chord (and wing surface area) and then increases camber.

This produces a flap which can optimize both takeoff (partial extension for optimal lift) and landing (full extension for optimal lift and drag) performance.

Double Slotted Fowler Flap

This design improves the performance of the Fowler flap by incorporating the boundary layer energizing features of the slotted flap.

First known use

The term comes from the 16th century from the Dutch word flappe, meaning something that hung wide and loose, tied only one way. The history of flap surgery dates back to 600 BC, when Sushruta Samhita described the reconstruction of the nose using a cheek flap. The origins of front rhinoplasty can be traced to around 1440 AD in India.

 

Use cases

  • flap on the wing of an aircraft is an area from the brink of the wing that can be elevated or decreased to control the motion of the aircraft.
  • The 777 does not have the wiring connecting wing flaps and rudder to the pilots’ adjustment.
  • Collision detective is focusing on a difficulty with the plane’s wing flaps and the shortcoming of a cockpit alarm to sound.
  • The wing flaps and the airframe were also impaired while the pilot was adjusting its wheels

 

Frequently Asked Questions

Why use the flaps?
Its goal is to generate more lift at slower speeds, allowing the aircraft to fly at a significantly reduced speed with a lower risk of stall. This is helpful for takeoff and landing.

 

What are the flaps called?
External folds are called labia majora. Internal folds are referred to as minor lips.

 

What are the standard flaps?
The most common flaps are Fowler, slit and flat. Many jet aircraft have Krueger flaps, which have been fitted to the leading edge of the wings. Besides altering the chamber, the type of flaps Fowler, Fairey-Youngman and Gouge expand the surface of the wing.

 

Who invented the flaps for airplanes?
Orville Wright and James M. H. Jacobs created it in 1920, but it was not used extensively until the 1930s, when it was quickly replaced.

 

Flaps video Explanation

This video will give you further explanation on the meaning of flaps on an aircraft, its location and how it helps in the movement of an airplane.

 

Summary

An airplane’s wings’ trailing edges include moveable surfaces called flaps that are used to increase lift and decrease drag.
Its primary function is to provide lift at slower airspeed so that the airplane may fly at a slower speed with less chance of stalling. This is very helpful during taking off and landing.
