Abstract
A method of manufacturing the aerofoil, and an aerofoil. The method includes: casting a first body portion having a passage passing there-through; casting a second body portion; and joining the first body portion and the second body portion to form the aerofoil. The passage extends from an opening at a first end at or near a leading edge to an opening at a second end at or near a trailing edge. The passage is formed during the casting process by a core; and the core is supported at the first and second ends through the respective openings of the passage.
