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.
An aerofoil having a leading edge and a trailing edge, the leading edge and trailing edge connected by a pressure surface side and a suction surface side and one or more cavities bounded by at least one of the pressure surface side or the suction surface side and arranged, in use, to receive coolant from a coolant source, the trailing edge having an apogee where the pressure surface side and the suction surface side meet and wherein a row of holes is provided with the centres of the holes arranged to a pressure surface side or a suction surface side of a centreline of the apogee the holes in fluid communication with one or more of the cavities the arrangement being such that outlets to the holes extend from the apogee and onto an adjacent part of the pressure surface side or the suction surface side.
