Here's the press release:
World's first serial hybrid electric aircraft to fly at Le Bourget
Munich, Germany, 2011-Jun-20
Siemens AG, Diamond Aircraft and EADS are set to
present the world's first aircraft with a serial
hybrid electric drive system at the Paris Air
Show Le Bourget 2011. The two-seater motor glider
successfully completed its maiden flight on June
8 at the Wiener Neustadt airfield in Vienna,
Austria. The aircraft was built by the three
partners to test the hybrid electric drive
concept. In the future, the technology, which is
intended for later use also in large-scale
aircraft, will cut fuel consumption and emissions
by 25 percent, compared to today's most efficient aircraft drives.
The world's first series hybrid electric plane DA36 E-Star
Electromobility is now making inroads into the
world of aircraft. The technology of the series
hybrid electric drive is scalable and will be
used in small and medium-sized aircraft and, in
the medium term, larger planes. It will make aviation greener.
Air traffic accounts for some 2.2 percent of CO2
emissions worldwide. For this reason, aircraft,
too, must become more efficient. One possible
solution which Siemens and its partners Diamond
Aircraft and EADS are testing in the DA36 E-Star
motor glider is to electrify the drive system.
"A serial hybrid electric drive can be scaled for
a wide range of uses, making it highly suitable
for aircraft as well," said Dr. Frank Anton, the
initiator of electric aircraft development at
Siemens. "The first thing we want to do is test
the technology in small aircraft. In the long
term, however, the drive system will also be used
in large-scale aircraft. We want to cut fuel
consumption and emissions by 25 percent, compared
to today's most efficient technologies. This will
make air travel more sustainable."
The motor glider, which is based on Diamond
Aircraft's HK36 Super Dimona, is the only
aircraft of its kind in the world. It is the
first to use a so-called serial hybrid electric
drive, which has been utilized to date only in
cars, as an integrated drive train. The plane's
propeller is powered by a 70kW electric motor
from Siemens. Electricity is supplied by a small
Wankel engine from Austro Engine with a generator
that functions solely as a power source. A
Siemens converter supplies the electric motor
with power from the battery and the generator.
Fuel consumption is very low since the combustion
engine always runs with a constant low output of
30kW. A battery system from EADS provides the
increased power required during takeoff and
climb. The accumulator is recharged during the
cruising phase. "The serial hybrid electric drive
concept makes possible a quiet electric takeoff
and a considerable reduction in fuel consumption
and emission," said Christian Dries, the owner of
Diamond Aircraft. "It also enables aircraft to
cover the required long distances."
The electric motor glider successfully completed
its first flight at the Wiener Neustadt airfield
in Vienna, Austria on June 8, 2011. "On the long
way to hybrid electric-powered commercial
aircraft, the maiden flight of the DA36 E-Star is
a small step and at the same time a historic
milestone," said Dr. Jean Botti, Chief Technical
Officer and member of the Executive Committee of EADS.
The next development step will be to further
optimize the entire drive train. Siemens
scientists are currently working on a new
electric motor that is expected to be five times
lighter than conventional drives. In two years,
another aircraft is expected to be equipped with
an ultra-light electric drive. Siemens' Drive
Technologies Division has already used integrated
drive trains in other applications like marine
drives. The knowhow gained in these areas has now
been applied in the aviation industry as well.
Combined with the corresponding product
portfolio, the components of the drive train can
be optimally adjusted to one another.
The DA36 E-Star will be exhibited at the Paris
Air Show Le Bourget in a flight demonstration
every day from June 20 to June 26, 2011.

Betcha this is being paid for by the long suffering European taxpayers.
God I hate this green bullshit.

Oooh errrrr.
If it is anything like the control system that Siemens use on CNC
machines, we're in trouble!
