Abstract: A system includes: a first electrical machine; a motor controller device coupled to the first electrical machine, wherein the motor controller device is configured to convert first power generated by the first electrical machine or provide second power to the first electrical machine; and a set of coupling devices configured to mechanically couple or decouple the first electrical machine and a turbine engine based on a mode of the system. The set of coupling devices includes: a first gearbox coupled to the first electrical machine; a first coupling device between the first gearbox and the turbine engine; a second gearbox; a second coupling device between the second gearbox and the turbine engine; and a third coupling device between the first gearbox and the second gearbox.

Abstract: A disconnect mechanism comprises an input shaft defining a drive axis, a disconnect shaft selectively engaged with the input shaft to be driven about the drive axis by the input shaft, and a disconnect ramp operatively connected to the disconnect shaft to axially move the disconnect shaft between at least a first axial position and a second axial position. A disconnect pawl is selectively engaged with the disconnect ramp shaft, and a brake is selectively engaged with the disconnect shaft in the second axial position.

Abstract: An aircraft includes an electrical system and an electronic controller in signal communication with the electrical system. The electronic controller including a main processor and a multi-core processor. The multi-core processor includes one or more control cores and one or more prognostic cores. The control core is in signal communication with the electrical system to control power delivered thereto. The prognostics core is configured to process prognostics and diagnostics data of the electrical system independently from operation of the control core.

IPC: H02P23/00
Abstract: A method of controlling a motor controller includes receiving respective measurements for each of at least three phase currents or voltages output by the motor controller that were instantaneously sensed at substantially the same instant, determining a magnitude of a model signal that models the sensed phase currents or voltages at the instant of the instantaneous sensing as a function of each of the respective measurements, and controlling the motor controller based on the magnitude of the model signal. A motor controller and a controller of a motor controller using the method are also provided.

CPC classification number: G01R31/086 , H02J3/36
Abstract: A system includes four high voltage direct current (HVDC) feeders, each having a first contactor configured for selectively connecting a positive terminal of an HVDC source to the respective HVDC feeder, and having a second contactor configured for selectively connecting the respective HVDC feeder to an HVDC bus. A power converter can be configured to use feedback to locate a fault when a fault arises, and to isolate the fault by opening of the contactors as needed for continued operation of as many of the HVDC feeders as possible after clearing the fault.

Abstract: An aircraft includes an electrical system and an electronic controller. The electronic controller includes a main processor and a multi-core processor. The multi-core processor includes a control core in signal communication with the electrical system, and one or more prognostics cores configured to process and analyze prognostics and diagnostics data of the electrical system independently from operation of the control core. A wireless device is in signal communication with one or more of the prognostics cores to receive the prognostics and diagnostics data therefrom. The aircraft further includes a prognostics and health monitoring (PHM) system located remotely from the electronic controller. The PHM system is configured to wirelessly receive the prognostics and diagnostics data from the wireless device.
