摘要： A system of a machine includes a network of a plurality of nodes distributed throughout the machine. Each of the nodes is operable to communicate through a plurality of electromagnetic signals. A controller is operable to communicate with the network of nodes through the electromagnetic signals. A plurality of waveguides is configured to confine transmission of the electromagnetic signals between the controller and one or more of the nodes. A radio frequency antenna is coupled to a first end of a first waveguide of the plurality of waveguides. A radio frequency transceiver is coupled between the controller and the radio frequency antenna. A capacitively coupled membrane at a second end of the first waveguide is configured to establish communication between the first waveguide and at least one node of the plurality of nodes.

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.

摘要： A system of a machine includes a network of a plurality of nodes distributed throughout the machine. Each of the nodes is operable to communicate through a plurality of electromagnetic signals. A controller is operable to communicate with the network of nodes through the electromagnetic signals. The system also includes a plurality of waveguides configured to guide transmission of the electromagnetic signals between the controller and one or more of the nodes. A radio frequency-based repeater is coupled to at least two of the waveguides in the network between the controller and at least one of the nodes. The radio frequency-based repeater is configured to receive a portion of the electromagnetic signals in a first waveguide and boost a transmission characteristic of the portion of the electromagnetic signals in a second waveguide.

摘要： A method of operating a gas turbine engine includes commanding an acceleration of the gas turbine engine and moving a variable pitch high pressure compressor vane toward an open position thereby reducing an acceleration rate of a high pressure turbine rotor thereby reducing a change in a clearance gap between the high pressure turbine rotor and a blade outer airseal. An active clearance control system of a gas turbine engine includes an engine control system configured to command an acceleration of the gas turbine engine and move a variable pitch high pressure compressor vane toward an open position thereby slowing an acceleration rate of a high pressure turbine rotor thereby reducing a change in a clearance gap between the high pressure turbine rotor and a blade outer airseal located radially outboard of the high pressure turbine rotor.
