ABSTRACT:
A guide vane100is provided in which sheet portions14, 15are secured together to define an aerofoil profile11. Between ends20, 21of the guide vane100there is a non linear variation in the maximum chordal thickness13. Thus, greater maximum chordal thickness13bin central portions of the guide vane100provide stiffness while ends20, 21which are generally formed from solid material have a smaller maximum chordal thickness such that a stiffer vane100can be provided with reduced material weight and therefore costs.
