<p>Fan blades (14) of a rotor stage (12) do not have platforms and separate wall members (20) are provided to bridge the space between adjacent blades (14). The wall members (20) define an inner wall of a flow annulus through the rotor (12). Each of the wall members (20) has a plurality of hooks (27) and (28) which extend radially inwardly to engage correspondingly shaped hooks (30) and (31) provided on the radially outer face (18) of the disc (16). Further hooks (29, 38) engage rings (34, 36) mounted on the rotor (12) adjacent the disc (16) to lock the wall member (20) in position. This ensures that the hooks (27) and (28) on the wall member (20) engage the hooks (30) and (31) on the radially outer face (18) of the disc (16).</p> |
