Abstract
An annulus filler () is provided for mounting to a rotor disc () of a gas turbine engine and for bridging the gap between two adjacent blades attached to the rotor disc (). The annulus filler () has an outer part () which defines an airflow surface for air being drawn through the engine, and a separate, support part () which is connectable to the outer part () and to the rotor disc () to support the outer part () on the rotor disc (). The outer () and support parts () are configured to allow a procedure for mounting the annulus filler () to the rotor disc (). In a first step the support part () is connected to the rotor disc () without the outer part (), and in a subsequent second step the outer part () is connected to the support part ().
