Abstract
A system includes a nacelle, a gas turbine engine, and an electrical machine. The nacelle includes an upper bifurcation and an engine core compartment. The gas turbine engine includes a low pressure spool and is disposed within the nacelle. The electrical machine is disposed within the upper bifurcation and is configured to transfer mechanical power between the low pressure spool and the electrical machine.
Claims20
A system comprising:
- a nacelle including an upper bifurcation and an engine core compartment;
- a gas turbine engine including an engine core disposed within the nacelle;
- an electrical machine disposed within the upper bifurcation and configured to transfer mechanical power between the engine core and the electrical machine;
- and
- a thermal management system (TMS) configured to cool (i) the electrical machine and (ii) a controller configured to control an operation of the electrical machine.

A line replaceable unit (LRU) comprising:
- an electrical machine configured to transfer mechanical power between an engine core of a gas turbine engine and the electrical machine;
- and
- a thermal management system (TMS) configured to cool (i) the electrical machine and (ii) a controller configured to control an operation of the electrical machine,
- wherein the line replaceable unit is configured to be disposed within an upper bifurcation of a nacelle configured to house the gas turbine engine within the nacelle.
1 more element
An aircraft comprising:
- a nacelle including an upper bifurcation and an engine core compartment, the nacelle mounted to the aircraft via a pylon;
- a gas turbine engine including an engine core, the gas turbine engine disposed within the nacelle and mounted to the nacelle via at least two thrust links disposed atop the gas turbine engine and below the pylon;
- an electrical machine configured to transfer mechanical power between the engine core and the electrical machine, the electrical machine disposed at a top, centered position above the gas turbine engine between the thrust links;
- and
- a thermal management system (TMS) configured to cool (i) the electrical machine and (ii) a controller configured to control an operation of the electrical machine.
