Abstract:
A nose cone may have a spinner including a main portion and an axially extending stepped portion. The nose cone may also have an annular aft support ring radially secured to the axially extending stepped portion. The nose cone may further include a fairing, which may be secured to the stepped portion.
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 may include a substantially-flat inner surface having frustoconical geometry. A flange having semi-torroidal geometry may extend from the spinner with an inner curved surface of the flange being tangential to the inner surface. A mating portion may extend substantially tangentially from the inner curved surface of the flange and configured for fastening to a fan hub.
Abstract:
A method of fabricating a fan case for a gas turbine engine defines a metallic ring including an outer surface and an inner surface. A first composite material is assembled about the outer surface of the metallic ring. A second composite material is assembled about the first composite material. The first composite material and the second material are cured about the metallic ring within a tool to form a first subassembly. The first subassembly is removed from the tool. A fan case assembly for a gas turbine engine and a gas turbine engine are also disclosed.
Abstract:
A gas turbine engine impact liner is disclosed. The impact liner may include a base sheet, a plurality of stanchions extending from the base sheet, and a plurality of supports, each being operatively associated with one of the plurality of stanchions.

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:
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.
