Abstract
A fan rotor has separate wall members bridging the space between adjacent blades of the rotor to define an inner wall of a flow annulus through the rotor; each wall member is attached to the radially outer face of a disk and opposing side faces to which resilient seal strips are bonded; the seal strips have flange portions which are inclined radially inwardly along a curved edge to produce undulations to enhance the flexibility of the flange portion so that, in operation, as the fan rotor rotates about a central axis of the engine, the flange portions are deflected radially outwardly by centrifugal forces into sealing contact with the adjacent fan blade to seal the inner wall of the flow annulus.
