Abstract
An aero-engine is provided with an integrated switched reluctance generator permanently connected to the low speed spool of the engine such that “windmilling” of the engine enables the generator to be turned if the engine suffers a flame out. The generator is driven by a step up gearbox so as to provide reasonable electrical output, say 25 kW, during flameout whilst keeping the generator weight down.
