Abstract: Plated polymeric articles having a composite layup structure and method of making the same are disclosed. A plated polymeric article comprises a composite layup having first and second polymer layers. The plated polymeric article further comprises a first metal plated onto the polymer. Additionally, methods for fabricating a plated polymeric article are disclosed. A composite layup is provided and compression molded into a desired shape having an outer surface. The outer surface of the article is prepared to receive a catalyst and then is activated with the catalyst. A first metallic layer is then plated onto the outer surface.

Abstract: Plated polymeric gas turbine engine parts and methods for fabricating lightweight plated polymeric gas turbine engine parts are disclosed. The parts include a polymeric substrate plated with one or more metal layers. The polymeric material of the polymeric substrate may be structurally reinforced with materials that may include carbon, metal, or glass. The polymeric substrate may also include a plurality of layers to form a composite layup structure.

Abstract: A spinner for a gas turbine engine is disclosed. The spinner may include a body extending between a first and second end comprised of a cured chopped unidirectional fiber pre-impregnated material. The body may have a generally conical shape and may further be plated with a metal or metal alloy.

Abstract: An assembly for a turbine engine including a nosecone that extends along an axis between a tip end and a second end. The nosecone includes a base region and a deformation region configured integral with the base region. The base region is arranged axially between the deformation region and the second end. The deformation region is adapted to deform relative to the base region upon impact of an object, and includes a stress concentrator.

Abstract: A duct has: a first non-metallic member extending between a first end and a second end, at least at the first end having an outwardly-projecting flange portion; a metallic flange member having a sleeve extending between a first end and a second end and a flange extending outward from the sleeve and having a first face and a second face; and a second non-metallic member extending between a first end and a second end having an outwardly-projecting flange portion, the first non-metallic member flange portion mounted to the flange first face and the second non-metallic member flange portion mounted to the flange second face.

Abstract: A spinner for a fan assembly of a gas turbine engine, a method of fabricating a spinner for a fan assembly of a gas turbine engine, and a gas turbine engine are disclosed. The fan section may include a nosecap. The spinner may include a forward end, an aft end, and a return flange associated with the forward end. The return flange may include a forward flange extending forward towards the nosecap and an aft flange extending aft towards the aft end.

Abstract: A spinner for a gas turbine engine comprises an outer shell for defining an airflow path when mounted in a gas turbine engine. An inner surface is provided with a plurality of webs. A gas turbine engine and a fan section for a gas turbine engine are also disclosed.

Abstract: A fan hub assembly for a gas turbine engine includes a fan hub that is configured to rotate about an axis. The fan hub has an axially extending aperture and a platform. A fastener is received in the aperture in a slip fit relationship to secure the platform to the fan hub.

Abstract: A duct has: a first non-metallic member extending between a first end and a second end, at least at the first end having an outwardly-projecting flange portion; a metallic flange member having a sleeve extending between a first end and a second end and a flange extending outward from the sleeve and having a first face and a second face; and a second non-metallic member extending between a first end and a second end having an outwardly-projecting flange portion, the first non-metallic member flange portion mounted to the flange first face and the second non-metallic member flange portion mounted to the flange second face.
