ABSTRACT:
A stage of fan blades in a ducted fan gas turbine engine have the spaces between them filled by a rotary annulus wall filler which has a leading portion made from metal and a trailing portion made from a composite material. The metal portion resists the impact damage from the ingress of foreign bodies and the trailing portion provides a lighter structure.
