Abstract:

The advancements in performance and reliability of high power semi-conductors make it possible to develop new system architectures for the general systems of the aircraft. The electrification of classical systems like actuation or environment control systems allows, depending on the vehicle requirements, a system architecture with only electrical power supply. On the other hand the requirements for the electrical system increase drastically. It has not only to provide more electrical energy, but also in different power qualities and of increased voltage. The most important aspect for the electrical system design is that it is now the critical power source for the primary flight control system. Therefore, a very high reliability has to be part of the design. On the equipment side the power distribution and power controlled equipment plays a major role in the ability to dispatch the available power in relation to flight phase or emergency cases. Modern motor control units allow to operate actuators, pumps or compressors with high efficiency. This allows to reduce the overall off-take power from the engine, the fuel consumption and the aircraft IR and radar signature stealth design or to increase endurance. This paper discusses possible architectures of More Electric Aircraft as well as features and performance of equipment which was developed within the research programme.
