Aerofoil Description

  • Leading Edge - edge facing the airstream
  • Trailing Edge - edge downstream
  • Chord - straight line joining the leading and trailing edges
  • Thickness - depth of the aerofoil
  • Camber - curvature of a line equidistant between upper and lower surfaces.
  • Angle of Attack - The angle between the Relative Airflow (RAF) and the Chord line.

Centre of Pressure

All aerodynamic forces on the aerofoil may be represented by a single resultant acting through a single point - this point is the centre of pressure.
