    摘要： A rotor disc (2) is provided with blade receiving recesses (40) at its outer periphery. The disc (2) has an internal cavity (34) for conveying cooling air to blades (4) retained in the recesses (40). Each blade-receiving recess (40) intersects the cavity (34) to provide communication between the cavity (34) and the recesses (40). The disc (2) may be made from separate disc components (12,14) which define the cavity (34) between them.
    A method of manufacturing such a rotor disc is also described.

    摘要： A fluid flow machine comprises an array of vanes (2) which are supported at their ends by inner and outer support structures 4, 6. The ends of the vanes are received in slots 8, 10, with resilient material 12 disposed between the vane 2 and the wall of the slot 8, 10. A restraint element 14, 34 is mounted in a recess 26, 28; 48 of the support structure 4, 6 and is engaged by a notch 30, 32 in the vane 2 to restrict axial displacement of the vane 2. Consequently, vibration of the vane in directions perpendicular to the lengthwise direction of the vane are damped by the elastomeric material 12 but bodily axial displacement of the vane 2 is prevented by the restraint elements 14, 34.
