Aerofoil for axial-flow machine

Abstract

An aerofoil, such as a vane, for an axial flow machine, the aerofoil having first and second ends and opposing pressure and suction surfaces extending between said first and second ends in a span-wise direction. A first portion of the span of the aerofoil towards the first end the aerofoil has a location of greatest camber which is closer to a trailing edge than a leading edge of the aerofoil. In a further portion of the aerofoil span the camber is either uniform between the leading and trailing edges or else a location of greatest camber is closer to the leading edge than the trailing edge. In the first portion of the span of the aerofoil the pressure and/or suction surface may turn to a greater extent towards the trailing edge than towards the leading edge of the aerofoil.
