Abstract: A hollow aerofoil is described having a leading edge and a trailing edge. The leading edge and trailing edge are connected by a pressure surface side (34) and a suction surface side (37) and one or more cavities are bounded by the pressure surface side (34) and/or suction surface side (37). In use, the cavity is arranged to receive coolant from a coolant source. The trailing edge has an apogee (36) where the pressure surface side (34) and suction surface side (37) meet. In an embodiment, a row of holes (32) is provided to a pressure surface side of a centreline of the apogee (36), the holes (32) being in fluid communication with cavity. The arrangement of the holes is such that outlets (33) to the holes extend from the apogee (36) and onto an adjacent part of the pressure surface side (34). A method for the manufacture of the aerofoil is also described.
