摘要： A fault diagnostic system includes an RF network that implements a plurality of devices in signal communication with a plurality of nodes to exchange a plurality of signals. A first device includes a radio frequency transceiver, and a first waveguide extends from a first end coupled to the first device to an opposing second end located at a second location. A processor transmits a first radio frequency signal among the plurality of signals through the first waveguide toward the second end, and receives a second radio frequency signal among the plurality of signals, the second radio frequency signal generated in response to the first radio frequency signal. The processor further performs at least one S-parameter analysis based on the first radio frequency and the second radio frequency, and determines a presence of a fault in the radio frequency network based on the at least one S-parameter analysis.

摘要： A seal assembly configured to reduce fluid flow from an axially upstream side of the seal assembly to an axially downstream side of the seal assembly includes a primary seal and a secondary seal assembly disposed at an axially forward end of the primary seal. The secondary seal assembly includes a seal support and a secondary seal. The seal support includes a downstream axial face disposed axially proximate to and facing the primary seal, an upstream axial face opposite the downstream axial face, a body extending from the downstream axial face to the upstream axial face, a first leg extending radially inward from the body, a second leg extending radially inward from the body, and a mistake-proofing protrusion extending from the upstream axial face and in an axially upstream direction.

摘要： An aircraft includes a communication system having a node and includes a method of operating the aircraft with the communication system. The communication system includes a waveguide and the node. The node is located in a high temperature environment. The node includes a high temperature logic circuit, a power supply, wherein the high temperature logic circuit and the power supply are disposed on a first side of the node in a high temperature environment, and a transponder disposed on a second side of the node. A sensor and/or an actuator can be operated via communication with the node via the waveguide.

摘要： An assembly is provided for a turbine engine. This assembly includes a housing, a combustor and a fuel injector assembly. The housing includes a case and a diffuser plenum radially within the case. The case extends axially along and circumferentially about a centerline. The combustor is disposed within the diffuser plenum. The combustor includes a bulkhead, a hood, a combustion chamber and a hood cavity. The bulkhead is axially between the combustion chamber and the hood cavity. The hood is between the hood cavity and the diffuser plenum. The fuel injector assembly projects radially into the diffuser plenum from the case. The fuel injector assembly includes a fuel nozzle and a steam nozzle. The fuel nozzle is configured to inject fuel into the combustion chamber. The steam nozzle is configured to inject steam into the hood cavity.

摘要： A method is provided for operating a turbine engine. During this method, fuel is injected into a combustion chamber of a combustor of the turbine engine. The combustion chamber extends circumferentially around a centerline. The fuel is combusted within the combustion chamber. Steam is introduced into the combustion chamber in an asymmetric pattern around the centerline.
