Abstract:
An electrical machine is embedded into the compressor assembly of a gas turbine engine. An electrical system interface module distributes electrical current to and from the embedded electrical machine for starting the gas turbine engine and for operating accessory components. Accordingly, the gas turbine engine and accessory components can be started and operated without a power-takeoff shaftline and without an external accessory gearbox.
Abstract:
An electric device is disclosed capable of generating heat during operation. The electric device can be in thermal communication to dissipate the heat through the use of carbon nanotubes and/or a phase change material. In one form the electric device includes a housing that has the carbon nanotubes. The housing, furthermore, can be a composite that in some embodiments does not provide as effective heat transfer as the carbon nanotubes. The electric device can take the form of a power electronic device in some embodiments and a device having a rotor and stator in others. Such embodiments include motors and/or generators.
Abstract:
A system is disclosed one form of which is an aircraft that includes a pod capable of housing a work providing device. The pod can also include a thermal conditioning system and a power generation device that can be powered from the work providing device. The pod can provide thermal conditioning services and power services to a payload aboard the aircraft. In one non-limiting form the payload is a directed energy member that can be cooled using the thermal conditioning system and powered using the power generation device.
Abstract:
A turbine engine compressor has a rotor including rotating compressor discs. Magnets are positioned on the rotating compressor discs. Electrical coils are positioned in a stationary guide vane internal ring so as to create an electric machine providing starting torque to a rotor, and/or generating electrical energy once the rotor is rotating.
