Annulus filler for a gas turbine engine

摘要

An annulus filler for mounting to a rotor disc of a gas turbine engine. The filler comprises a lid for bridging the gap between two adjacent blades attached to the rotor disc, and forward and rearward hook members projecting below the lid and configured to respectively engage with forward and rearward outwardly directed hooks provided on the rotor disc. The filler can further comprise a lip extending from the rear of the lid, the lip being configured to fit beneath a gas-washed element located rearwards of the annulus filler. One or more guide ramps then extend from the rear of the lip, the or each guide ramp being angled down relative to the lip to encourage the lip to slide beneath said fairing when the annulus filler is translated in the generally rearwards direction.
