In recent years, the More-Electric Aircraft (MEA) concept has undergone significant development and refinement, striving towards attainment of reductions in noise CO2 emissions, increased power transmission efficiency improved reliability under a range flight scenarios.The Engine (MEE) is increasingly being seen as key complementary system to MEA.With this concept, conventional engine auxiliary systems (i.e.fuel pumps, oil actuators) will be replaced by electrically-driven equivalents, providing even greater scope for combined aircraft electrical optimisation management.This coupled with extraction from multiple spools also potential deliver fuel burn savings.To date, single or dual channel generation distribution have been used engines aircraft.However, increasing electrification flight-critical auxiliaries along requirement load transfer flexibility, threechannel architecture should considered.This paper investigates concepts three-channel an MEE system.The considers issues such layout technologies that may considered architecture.Using extensive database public domain MEA/MEE component failure rates, detailed fault tree analysis then presented.This provides quantitative comparison candidates pertinent modes well showing impact common features on robustness.Finally, concludes discussion ring busbar topology operation electronics technology requirements could successfully implement flexible robust systems.
