Abstract:
A fuel injector is provided for a gas turbine engine. The fuel injector includes a fuel conduit and a cooling fluid circuit through a strut. A gas turbine engine is provided that includes a multiple of fuel injectors in communication with a combustor and a cooling system in communication with each of the multiple of fuel injectors.
Abstract:
A method for abrasive flow machining includes moving an abrasive media through a high-aspect passage (32) of a workpiece (30). Local pressure of the abrasive media is increased at target abrasion surfaces (36) of the high-aspect passage (32) using a passage geometry that is configured to direct flow of the abrasive media into the target abrasion surfaces (36) such that the target abrasion surfaces (36) are preferentially polished by the abrasive media over other, non-targeted surfaces (38) of the high-aspect passage (32) at which the flow of the abrasive media is not directed into.
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:
An article includes a body portion made of a metal and configured for use in a gas turbine engine, a sensing feature monolithically formed with the body portion, and an interior passage connected to the sensing feature and passing through the body portion. An article with integrated sensing features may be made additive manufacturing, resulting in a structure having internal passageways connecting an aperture at one surface of the monolithic article to a second aperture at another surface of the monolithic article at the opposite end of the internal passageway.
