摘要： An engine system (100) of an aircraft includes an energy storage system (218), a gas turbine engine (20), and a controller. The gas turbine engine (20) includes a low spool (30), a high spool (32), a low-spool generator (12B) operably coupled to the low spool (30), and a high-spool electric motor (13A) operably coupled to the high spool (32). The controller is configured to detect a braking condition of the aircraft, transfer power from the low-spool generator (12B) to the energy storage system (218) based on the storage capacity state of the energy storage system (218), and transfer power to the high spool (32) through the high-spool electric motor (13A) to support combustion in the gas turbine engine (20) while a rotational speed of the low spool (30) is reduced responsive to the low-spool generator (12B) extracting energy from the low spool (30).

摘要： A system of a machine includes a network (100) of a plurality of nodes (68a, 68b) distributed throughout the machine, a controller (66), and a plurality of waveguides (170, 171, 172, 173a, 173b, 173c, 174a, 174b). Each of the nodes (68a, 68b) is operable to communicate through one or more radio frequencies, where the machine includes a cooler portion and a hotter portion. The controller (66) is operable to communicate with the network (100) of nodes (68a, 68b) using a higher frequency to communicate with one or more of the nodes (68a, 68b) in the cooler portion of the machine and a lower frequency to communicate with one or more of the nodes (68a, 68b) in the hotter portion of the machine. The waveguides (170, 171, 172, 173a, 173b, 173c, 174a, 174b) are configured to guide transmission of the one or more radio frequencies between the controller (66) and one or more of the nodes (68a, 68b).

摘要： A geared turbofan engine (10) includes a first rotor (20), a fan (28), a second rotor, a gear train (26), a fan casing, a nacelle (12) and a plurality of discrete acoustic liner segments (38a, 38b, 38c, 38d, 38e, 38f). The fan (28) is connected to the first rotor (20) and is capable of rotation at frequencies between 200 and 6000 Hz and has a fan pressure ratio of between 1.25 and 1.60. The gear train (26) connects the first rotor (20) to the second rotor. The fan casing and nacelle (12) are arranged circumferentially about a centerline (C L ) and define a bypass flow duct (30) in which the fan (28) is disposed. The plurality of discrete acoustic liner segments (38a, 38b, 38c, 38d, 38e, 38f) with varied geometric properties are disposed along the bypass flow duct (30).

摘要： A multi-mode microwave waveguide blade sensing system (500) includes a transceiver, a waveguide (174b), and a probe sensor (176). The transceiver generates a microwave energy signal having a first waveguide mode and a different second waveguide mode. The waveguide (174b) includes a first end that receives the microwave energy signal. The probe sensor (176) includes a proximate end (178a) that receives the microwave energy signal from the transceiver and a distal end (178b) including an aperture that outputs the microwave energy signal. The probe sensor (176) 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 (176) 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 (200) of a machine includes a waveguide system (202) and a radio frequency transceiver/detector (204) coupled to the waveguide system (202) and configured to emit a calibration signal in the waveguide system (202) to establish a reference baseline between the radio frequency transceiver/detector (204) and a calibration plane (206) associated with an aperture (208) of the waveguide system (202), emit a measurement signal in the waveguide system (202) to transmit a radio frequency signal from the radio frequency transceiver/detector (204) out of the aperture (208) of the waveguide system (202), and detect a reflection of the measurement signal at the radio frequency transceiver/detector (204) based on an interaction between the measurement signal and a component (210) of the machine. A measurement result of the reflection of the measurement signal can be adjusted with respect to a reflection of the calibration signal.
