Abstract

A vane assembly (200) includes an aerofoil (201) having a leading edge (210), a trailing edge (220), a pressure surface (230) and a suction surface (240). The aerofoil (201) includes a blade member (250) forming the trailing edge (220), at least a portion of the pressure surface (230) and at least a portion of the suction surface (240). The blade member (250) is formed of a first material. The aerofoil (201) further includes a spar (260) at least partly enclosed by the blade member (250) and forming at least a portion of the leading edge (210). The spar (260) further forms at least one cooling channel (270) and supports at least a portion of an interior surface (255a, 255b) of the blade member (250). The spar (260) is formed of a second material different from the first material. The second material has a greater impact resistance than the first material.
