摘要:
A control system comprises a TRAS actuator 14, a VAFN actuator 40, and a control arrangement 52 operable to control the operation of the TRAS actuator 14 and the VAFN actuator 40, wherein at least one control circuit 54 of the control arrangement 52 is a common control circuit, common to the operation of both the TRAS actuator 14 and the VAFN actuator 40.
摘要:
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.
