IEEE Electrification Magazine - December 2017 - 38

By Nick Nagel

HE LAST SEVERAL DECADES
have witnessed an everincreasing drive toward
more electric aircraft
(MEA). This drive
stems from the need to improve
efficiency and reduce lifetime operating costs of the aircraft. Recently,
work has focused on the all-electric aircraft (AEA) in which everything, including propulsion, is
powered by electric machines
(Loff 2016, Aubert 2017).
While electric propulsion
for small aircraft is within current technical capabilities,
there are still limitations prohibiting this in larger aircraft. A
large commercial transport
plane such as the Boeing 777 or
Airbus A340 requires the propulsive power to be 60 MW or more
(Bowman et al. 2016). Even assuming the use of size- and weight-optimized electric machines, the challenge
