发明名称 Blade attachment retention device
摘要 An annulus filler (11) is provided for mounting to a rotor disc (10) of a gas turbine engine and for bridging the gap between two adjacent blades (22) attached to the rotor disc (10). The annulus filler (11) defines an airflow surface for air being drawn through the engine. The annulus filler (11) has one or more primary connectors (13, 14) for connecting the annulus filler (11) to the rotor disc (10), and for resisting, in use, centrifugal forces on the annulus filler (11). Each primary connector (13, 14) allows rotation of the annulus filler (11) around the centre line of the engine relative to the rotor disc (10) at that primary connector (13, 14). The annulus filler (11) also has a secondary connector (17,18,19) for connecting the annulus filler (11) to the rotor disc(10) and for resisting, in use, motion of the annulus filler (11) relative to the rotor disc (10) in a first axial direction. The secondary connector (17, 18, 19) allows rotation of the annulus filler (11) around the centre line of the engine relative to the rotor disc (10) at the secondary connector (17, 18, 19).
