청구항

1. A method of relighting a gas turbine engine of a fixed-wing aircraft after an in-flight engine-out condition, the engine having at least one electromagnetic bearing apparatus and at least a bladed propulsor mounted to a first shaft and a compressor and turbine mounted to a second shaft, the first shaft drivingly connected to a first electric generator, the method comprising: using windmill rotation of the bladed propulsor to drive the generator;using electricity from the windmill-driven first electric generator to provide power to the electromagnetic ...
