초록

A method of emergency operation of an aircraft turbofan engine during an aircraft flight is provided. The engine includes a fan shaft with a fan, and an electric motor/generator mounted for rotation therewith. The method includes shutting down the engine while allowing the engine to windmill, operating the electric motor/generator to rotate the shaft at a determined windmilling speed which is desired for the fan shaft, and operating the engine at the desired windmilling speed for substantially a remainder of the aircraft flight.

청구항

I claim: 1. A method of emergency operation of an aircraft turbofan engine during an aircraft flight, the engine having a fan shaft with a fan and an electric motor/generator mounted for rotation therewith, the method comprising the steps of: shutting down the engine while allowing the engine to windmill; determining a desired windmilling speed for the fan shaft, the desired windmilling speed being different from at least one shaft speed determined to be avoided; operating the electric motor/generator to rotate the shaft at said desired windmilling spee...
