  • 1. The Future of MEA - Developments with the most Potential The growing demand of power requirements is driven by additional and enhanced avionics systems. The main reason is the increased use of electromechanical and electro hydrostatical actuation, plus the higher passenger comfort with in-flight entertainment systems. At last year’s More Electric Aircraft conference, experts from Bombardier Aerospace, Liebherr-Elektronic GmbH and Safran Power UK shared their expertise on system architectures of the next generation aircraft on site. Read the interviews with Avraham Ardman - Chief Systems Engineer at Bombardier Aerospace, Dr.-Ing. Ralf Cremer - Managing Director Design and Engineering AER at Liebherr-Elektronik GmbH and Mark Wood - Engineering Director at Safran Power UK, here: IQPC: The growing demand of power require- ments for airplanes is driven by enhanced avi- onics systems and the increased use of electro- mechanical and electro hydrostatical actuation. Which developments and solutions for More Electric Aircraft (MEA) have the most potential, from your point of view? Avraham Ardman: From my perspective, these elec- tric systems can be more efficient by saving fuel and reducing emissions. This can be achieved with elec- tric ECS, electric ice protection, electric APU, bleed- less engine and improved power electronics. Ralf Cremer: Of course, electromechanical actua- tors (EMA) and electrohydrostatical actuators (EHA) are well suited for MEA, but also large and constant loads such as electrical environmental control sys- tems (E-ECS) and E-Wing-Ice-Protection-Systems should be taken into account. Another option is Green Taxiing. Next to the loads, the architecture of the electrical supply system, which could contain a static auxiliary power unit (APU), electrical storage and maybe power conditioning units, play an im- portant role. But from the view of potential, the highest effect is the clear commitment to consequently electrifying the MEA. This includes also the application of HVDC networks and AC networks, even in combination, depending on the aircraft structure. The efficiency of power electronics based on new technologies is in the focus, in order to reduce additional weight for dissipating these power losses by cooling systems. Furthermore, the effectiveness of electrical com- ponents depends on the overall installed electrical power. This would allow e.g. cost and energy saving with clever power management. Mark Wood: The areas that have the most potential for the MEA aircraft are where traditional hydraulic and pneumatic systems can be replaced by electri- callydriven systems. These areas are where there is a high usage of energy but low optimisation of elec- trification. Engines on airliners are highly efficient in flight, but not when operating on the ground espe- cially when taxiing. This is a key area of development in‘green-taxiing’using electric motors during taxiing to achieve huge fuel savings. Other key areas for the MEA aircraft are e-braking, electric engine start and advances in fuel cell technology. IQPC:Which are better, lighter and smarter mate- rials and components to enable MEA, maximize the functionality, durability and reliability and improve power and energy management?
