초록 ▼

A liner for a composite blade of a gas turbine engine includes a metallic shoe, operable substantially to encase a blade root of a composite blade and defining an inner surface and an outer surface. The liner also includes a retention lug formed on the shoe and has inner and outer keys that project from opposed portions of the inner and outer surfaces. The keys engage corresponding recesses on a dovetail slot and a blade root to resist axial displacement of the composite blade.

대표청구항 ▼

1. A liner for a composite blade of a gas turbine engine, the liner comprising a metallic shoe for at least partially encasing a blade root of a composite blade, the metallic shoe having an inner surface, an outer surface, and a retention lug, wherein the retention lug comprises an outer key which projects from an outer surface of the retention lug and configured for axial retention of the blade,wherein the metallic shoe comprises a base portion and opposed flank portions, andwherein the retention lug is formed on a flank portion. 2. The liner as claimed in claim 1, wherein the retention lug further comprises an inner key which projects from an inner surface of the retention lug. 3. The liner as claimed in claim 2, wherein the inner and outer keys are located on opposing portions of the inner and outer surfaces. 4. The liner as claimed in claim 2, wherein the inner key of the retention lug comprises a stepped projection having at least one change in thickness. 5. The liner as claimed in claim 1, wherein the liner comprises two retention lugs, each lug formed on an opposed flank portion of the shoe. 6. The liner as claimed in claim 1, wherein the retention lug is metallic. 7. The liner as claimed in claim 1, wherein the retention lug is integrally formed with the shoe. 8. The liner as claimed in claim 1, wherein the retention lug is diffusion bonded to the shoe. 9. The liner as claimed in claim 1, wherein the outer key of the retention lug comprises a single projection having a constant thickness. 10. A blade assembly for a gas turbine engine, comprising a composite blade and the liner as claimed in claim 1. 11. The blade assembly as claimed in claim 10, wherein the liner is attached to the blade root of the composite blade by co-moulding. 12. The blade assembly as claimed in claim 10, wherein the liner is attached to the blade root of the composite blade by secondary bonding. 13. The blade assembly as claimed in claim 10, wherein the retention lug further comprises an inner key which projects from an inner surface of the retention lug, and wherein the inner key of the liner retention lug engages a corresponding recess formed on the blade root of the composite blade.
