ABSTRACT:
A nozzle guide vane structure for a gas turbine engine in which the vane comprises an aerofoil portion and inner and outer platforms. The non gas-contacting surfaces of the platforms are provided with forward and rearward sealing flanges sealed to adjacent engine structure to provide spaces sealed against ingress of working fluid between each pair of forward and rearward flanges. The mounting means for the vane projects into these spaces from the non gas-contacting surface.
