Airfoil and Wings

The cross-sectional shape that is obtained when a perpendicular plane cuts or interests the wing is called as an airfoil or an aerofoil.

 

Airfoil Terminologies

 

Mean Camber Line

    Mean Camber line is a line that is made up of a locus of points half way between the upper and lower surfaces of an airfoil.

 

Chord of an Airfoil

    The line joining the leading edge to the trailing edge of an airfoil is known as the chord line and the distance from the leading edge to the trailing edge of an airfoil is known as the chord which is denoted by c.

 

Camber

    The camber is the maximum distance measured perpendicular to the chord line between the mean camber line and the chord line.

 

Leading Edge

    The forward most point on an airfoil is known as the leading edge of an airfoil.

 

Trailing Edge

    The rearmost point on an airfoil is known as the trailing edge of an airfoil
