Abstract: A two piece spinner assembly comprises an inner structure and an outer structure. The inner structure is configured to provide structural support to the assembly, while axially retaining the fan blades of the engine in position. The outer structure is suitably placed over the inner structure such that the assembly forms a single conical unit. The spinner assembly suitably directs airflow into the engine and serves as an energy absorption device for FOD (foreign objects and debris) that may be ingested into the engine and/or impact the spinner assembly.
