A guide vane is adapted to be mounted in an annular fluid-conveying duct of a gas turbine engine, and has an aerofoil part which extends radially across the duct when the guide vane is thus-mounted. On a transverse cross-section relative to the direction of intended fluid flow across the aerofoil part, at least a portion of the aerofoil part is S-shaped.
