# aerofoil

[ˈerəʊfɔɪl]

## aerofoil Definition

a part of an aircraft wing that produces lift, typically consisting of a flat or curved piece fixed to the wing's surface.

## Using aerofoil: Examples

Take a moment to familiarize yourself with how "aerofoil" can be used in various situations through the following examples!

• Example

The aerofoil design allows the plane to take off and stay in the air.

• Example

The engineers tested different aerofoil shapes in the wind tunnel.

## Phrases with aerofoil

• ### symmetricalaerofoil

an aerofoil with the same shape on both sides of its chord line, producing no lift when at zero angle of attack

Example

A symmetrical aerofoil is often used in aerobatic planes.

• ### camberedaerofoil

an aerofoil with a curved upper surface and a flat lower surface, producing lift when at a positive angle of attack

Example

Most airplane wings use a cambered aerofoil design.

• ### thinaerofoiltheory

a mathematical model used to predict the lift and drag characteristics of an aerofoil based on its shape and the speed of the airflow over it

Example

The thin aerofoil theory is a simplified way to analyze the performance of an airplane wing.

## Origins of aerofoil

from 'aero-' meaning 'air' and 'foil' meaning 'wing'

📌

## Summary: aerofoil in Brief

An 'aerofoil' [ˈerəʊfɔɪl] is a part of an aircraft wing that produces lift, typically consisting of a flat or curved piece fixed to the wing's surface. The design of the aerofoil allows the plane to take off and stay in the air. Different types of aerofoils include symmetrical and cambered aerofoils, and the thin aerofoil theory is a mathematical model used to predict their performance.
