摘要： A radio frequency waveguide communication system includes a controller configured to output a radio frequency signal, and at least one connected node configured to output a node signal indicative of monitored parameter of a machine. The radio frequency waveguide communication system includes a waveguide and a radio frequency interface module. The waveguide is in signal communication with the controller and is configured to guide the radio frequency signal toward the at least one connected node. The radio frequency interface module is configured to establish signal communication between the controller and the at least one connected node, and includes at least one detachable portion configured to detach from the at least one waveguide.

摘要： A turbofan engine includes a first spool including a first turbine, and a first tower shaft engaged to the first spool. A second spool includes a second turbine, and a second tower shaft is engaged to the second spool. A superposition gearbox includes a sun gear, a plurality of intermediate gears engaged to the sun gear, and is supported in a carrier and a ring gear circumscribing the intermediate gears. The first tower shaft or the second tower shaft drives one of the intermediate gears. A drive motor is engaged to drive the sun gear, an inner electric motor, a stator disposed radially outside of the inner electric motor, and an outer electric motor disposed radially outside the stator. A first load on the first spool and a second load on the second spool is adjusted by operation of at least one of the inner electric motor and the outer electric motor.

摘要： A gas turbine engine includes a generator that is configured to be driven by a turbine section, an electric motor that is configured to receive at least a portion of electric power from the generator, a gearbox that is mechanically coupled to both the electric motor and the generator, and a control system that has an operational amplifier that is configured to synchronize operation of the electric motor and the generator. The operational amplifier electrically couples the electric motor to the generator and is configured to define an electrical gain that matches a mechanical gain that is defined by the gearbox.

摘要： A propulsion system for an aircraft is disclosed and includes a water recovery system and a water monitoring system. The water recover system includes a condenser that is arranged along the core flow path and is configured to extract water from an exhaust gas flow. The water monitoring system includes a sensor and a controller programed to determine a condition of water and generate a prompt based on information communicated from the at least one sensor.

摘要： A system of a machine includes a first node and a second node configured to establish a first communication path through a waveguide system to guide a radio frequency transmission between the first node and the second node in the machine. The system also includes a third node and a fourth node configured to establish a second communication path in the machine. The first node is grouped with the third node as a first node group, and the second node is grouped with the fourth node as a second node group such that the second communication path provides a redundant communication path with respect to the first communication path for communication between the first node group and the second node group.

摘要： According to an aspect, a waveguide system includes a first node, a second node, and a double-ridge waveguide. The double-ridge waveguide includes a metallic shell surrounding a waveguide core that forms a communication and radio frequency power transmission path in an aerospace environment. The first node is configured to propagate at least one communication channel and a radio frequency power transmission through the waveguide core to the second node during operation of the waveguide system in the aerospace environment.

摘要： A multi-mode microwave waveguide blade sensing system includes a transceiver, a waveguide, and a probe sensor. The transceiver generates a microwave energy signal having a first waveguide mode and a different second waveguide mode. The waveguide includes a first end that receives the microwave energy signal. The probe sensor includes a proximate end that receives the microwave energy signal from the transceiver and a distal end including an aperture that outputs the microwave energy signal. The probe sensor directs the microwave energy signal at a first direction based on the first waveguide mode and a different second direction different based on the second waveguide mode. The probe sensor receives different levels of reflected microwave energy based at least in part on a location at which the at least one microwave energy signal is reflected from the machine.

摘要： A system of a machine includes a network of nodes distributed throughout the machine. Each of the nodes is operable to communicate through electromagnetic signals. The system also includes a radio frequency transceiver, a first antenna coupled to the radio frequency transceiver, a second antenna coupled to one or more sensor nodes, and a controller coupled to the radio frequency transceiver. The controller is configured to select at least one sensor node to interrogate, transmit one or more interrogation frequencies from the radio frequency transceiver through the first antenna to the second antenna, receive one or more sensor frequencies at the first antenna broadcast from the second antenna based on a frequency response of the at least one sensor node to the one or more interrogation frequencies, and determine one or more sensed values based on the sensor frequencies received at the radio frequency transceiver through the first antenna.
