Abstract
A significant effort is being invested internationally in the research of Power Optimised Aircraft (POA). Advances in electrical machine and power electronics technologies have led to the concept of the POA, or More Electric Aircraft (MEA). This will result in significant changes to aircraft power systems and will facilitate the optimisation of the airframe and engine systems by replacing conventional heavy and maintenance-intensive components such as pneumatic and hydraulic power systems with predominantly electrically powered systems. This paper will present an overview of a number of issues and research challenges that are associated with this next generation of aircraft, with particular emphasis on the more electric engine. It will review electrical protection methods presently used within the aerospace industry and will examine the technology developments that are currently driving this area of research. The protection system requirements for the increased complexity of the more electric engine's electrical systems will be reviewed, and a discussion of the potential issues and possible solutions will be presented.
