One example aspect of the present disclosure is directed to a method for enhancing a maintenance operation routine. The method includes receiving, at one or more processors, engine history data. The method includes comparing, at the one or more processors, the received engine history data to expected engine history data. The method includes determining, at the one or more processors, an expected effectiveness of a plurality of maintenance operation types based on the comparison. The method includes selecting, at the one or more processors, one of the plurality of maintenance operation types based on the determinations. The method includes transmitting, at the one or more processors, a signal indicative of a notification of the selected maintenance operation type.

Maintenance operation analytics

An additively manufactured fastener and a method of manufacturing the same are provided. The fastener includes a shank defining an internal passageway and a head defining a distribution plenum in fluid communication with the internal passageway. The head further defines a cooling face defining a plurality of cooling holes for receiving a flow of cooling air from the internal passageway and the distribution plenum. In addition, an impingement baffle is positioned in the distribution plenum and defines impingement holes for directing the flow of cooling air onto the cooling face.

Additively manufactured mechanical fastener with cooling fluid passageways

A system and method for cleaning an installed gas turbine engine is provided. The system may include a controller on an engine core, wherein the engine core defines a primary gas path and includes at least one airfoil extending into the primary gas path. The method may include initiating a cleaning program and directing a cleaning fluid toward the engine core in response to the initiation of the cleaning program. The method may further include initiating delivery of the cleaning fluid as a non-vaporized liquid within the primary gas path to the engine core.

Turbine engine cleaning systems and methods

A rotor blade formed via additive manufacturing is provided. The rotor blade includes an airfoil and a coupled component. The airfoil includes a plurality of fused layers of a first material formed via additive manufacturing and defines a leading edge and a tip at a distal end. The coupled component includes a plurality of fused layers of a second material formed via additive manufacturing. An interlocking transition zone includes a plurality of projections alternately extending from the airfoil and the coupled component, respectively, to undetachably couple the airfoil and the coupled component.

Additively manufactured rotor blades and components

An apparatus for manufacturing an axi-symmetric part. The apparatus includes a vessel configured to contain the powder. The vessel is also configured to receive a part such that at least a portion of the part contacts the powder contained within the vessel. A first energy source is configured to generate a first beam of energy. The first beam of energy is configured to melt the powder at a first predetermined location such that the melted powder fuses to the part.

Additive machine utilizing rotational build surface

Turbine nozzles are provided for gas turbine engines. The turbine nozzle includes an arcuate inner band; an arcuate outer band; and a nozzle vane disposed between the arcuate inner band and the arcuate outer band. The radially inner end of the nozzle vane is attached to the arcuate inner band through an interlocking transition zone including a plurality of projections alternately extending from the radially inner end of the nozzle vane and the arcuate inner band, respectively, to undetachably couple the nozzle vane and the arcuate inner band. Optionally, the radially outer end of each nozzle vane is also attached to the arcuate outer band through an interlocking transition zone.

Additively manufactured connection for a turbine nozzle

A bladed disk for a gas turbine engine is provided. The bladed disk includes a rotor disk, a plurality of rotor blades, and an interlocking transition zone. The rotor disk includes a plurality of fused layers of a first material formed via additive manufacturing and defines an outer rim. The plurality of rotor blades includes a plurality of fused layers of a second material formed via additive manufacturing. The interlocking transition zone includes a plurality of projections alternately extending from the outer rim of the rotor disk and the plurality of rotor blades, respectively, to undetachably couple the rotor disk and the plurality of rotor blades.

Additively manufactured bladed disk

A method of joining two components using additive manufacturing is provided. The method includes forming a first component made of a first material; forming an interlocking transition zone from the first material and a second material; and forming a second component made of the second material. The interlocking transition zone includes a plurality of projections alternately extending from the first component and the second component, respectively, to undetachably couple the first component and the second component.

Interlocking material transition zone with integrated film cooling

Methods for repairing surface of a metal substrate are provided, which can include preparing the surface of the metal substrate for repair; melt attaching a base layer onto the surface of the metal substrate; fusing a plurality of first layers of a first material via additive manufacturing to the base coating; forming an interlocking transition zone via additive manufacturing from the first material and a second material; and fusing a plurality of second layers of the second material via additive manufacturing on the interlocking transition zone. The interlocking transition zone can have a plurality of projections alternately extending from the plurality of first layers and the plurality of second layers, respectively, to undetachably couple the plurality of first layers to the plurality of second layers. A repaired metal substrate is also provided.
