e Aviation Talk
Cartivator
In addition to the EAC Whisper, MGM also works with Bell.
one of the largest issues in the development of e-Aircraft:
Which are the best cells for aviation and where
do you see the maximum power density now and in
five years?
M.D.: The question does not have an easy answer! Depending
on the use case, the demands on the backs and
cells differ a lot. Packing and using have a large influence
on the safety and the lifetime of the batteries.
eFJ: As Battery density is a problem are you also
working on hybrid systems?
M.D.: As we are development partners also for e-motor
producers, we are also working on rage extenders. For
example we work with a Czech company which develop
a Hybrid system for ultralight aircraft which function on
the base of a Rotary dual disk motor which is currently
under development.
eFJ: Two years ago - with the Phenix project - you
also introduced a charging system...
M.D.: Yes! With this system we have shown that - in the
case of the Phenix- the battery could be charged in only
20 minutes up to 90%!This makes such an aircraft perfectly
usable for end users and schools already now.
eFJ: What is the largest project you are working on at
the moment?
M.D.: One of the most interesting projects is the electrification
of the modern Commuter plane EV 33 which is
right now under certification. We are in the final stage of
launching this project in the next weeks. The first phase
is an evaluation. It’s a government funded project for the
“proof of concept” of the electrification of a 14 seater
commuter project of the EV 55. The aircraft fits perfectly
to be electrified. Power requirement is to have 2 Motors
up to 400 Kw.
eFJ: With this aircraft you are entering the field of
“certified aircraft”.What do you think of a possible
certification?
M.D.: In the first phase – the next two years - we have to
prove that we can deliver a system for such continuous
power. Thinking of certification: The new design and all
components must be compliant to all existing. We try to
match all future certification requirements as they will be
developed by the authorities.
eFJ: Where do you think we are with the electrification
of aircraft at the moment?
M.D.: I think the systems are progressing a lot, so we are
closer and closer to electric flying.
eFJ: Thank you Martin for this talk.
M.D.: I thank you for having me and “Lets fly electric”! 4
