Abstract

An under-root fan blade (20) spacer (30) system (10) for a gas turbine engine includes a fan hub (12) having a fan hub receiver (14) with a hub receiver floor (28) and an opening configured to receive a fan blade root (18). The fan blade root (18) includes a base end (26). A gap (24) is formed between the base end (26) of the fan blade root (18) and the hub receiver floor (28). The spacer (30) disposable within the gap (24) includes a shape-memory-alloy material that allow for deformation from an original shape (32) to a deformed shape (34) and rebound back into the original shape (32). An under-root fan blade ( 20) spacer (30) is provided. A process of forming the under-root fan blade (20) spacer (30) system (10) for a gas turbine engine includes: forming the fan hub (12); and disposing the at least one spacer (30) within the gap (24).
