Airbus, Siemens and Rolls Royce Partner
on Electric Aircraft Propulsions

Rolls-Royce and Siemens are partnering to develop hybrid-electric
propulsion for commercial aircraft.
The E-Fan X hybrid-electric technology demonstrator could fly in
2020. It will be tested on a BAe 146 flying testbed, with one of
the aircraft’s four gas turbine engines replaced by a 2 megawatt
electric motor. A second gas turbine would be replaced with an
electric motor once the system is proven.
The E-Fan X follows a series of electric flight demonstrators,
starting with the Cri-Cri, and including the e-Genius, E-Star and
the E-Fan 1.2.
Airbus CTO Paul Eremenko said, “We see hybrid-electric propulsion
as a compelling technology for the future of aviation.”
The E-Fan X demonstrator will test high-power propulsion systems,
such as thermal effects, electric thrust management, altitude and
dynamic effects on electric systems and electromagnetic
compatibility issues. The objective is to push and mature the
technology, performance, safety and reliability enabling progress
to be made on the hybrid electric technology.
The program also aims to establish the requirements for future
certification of electrically powered aircraft.
Airbus will be responsible for overall integration as well as the
control architecture of the hybrid-electric propulsion system and
batteries and its integration with flight controls.
Rolls-Royce will be responsible for the turbo-shaft engine, 2 MW
generator and power electronics. Along with Airbus, Rolls-Royce
will also work on the fan adaptation to the existing nacelle and
the Siemens electric motor.
Siemens will deliver the 2 MW electric motors and their power
electronic control unit, as well as the inverter, DC/DC converter
and power distribution system. This comes on top of the
E-Aircraft Systems House collaboration between Airbus and
Siemens, which launched in 2016 and aims at developing electric
propulsion system components and their ground-based testing
across power classes.
The partners plan to meet the EU technical environmental goals of
the European Commission’s Flightpath 2050 Vision for Aviation:
reduction of CO2 by 75 percent, reduction of NOx by 90 percent
and noise reduction by 65 percent. These goals cannot be achieved
with existing technology, the companies say.

EV commitment from national climate

climate action leaders aim to accelerate states and territories’
transition to electric vehicles after signing an agreement at a
Climate Action Roundtable.
A memorandum of understanding (MoU) agreeing to develop a plan to
increase the EV share in their fleets and to consider combining
market power to promote EV public uptake was signed at a meeting
Representatives also agreed to coordinate the strategic planning
and construction of infrastructure for EVS and seek to align
states’ standards and incentives.
South Australia, Victoria, Western Australia and the Australian
Capital Territory, and the cities of Adelaide, Hobart and Darwin
participated in the roundtable.
They committed to urgently progressing action to reduce
greenhouse gas emissions and adapt to climate change impacts.
South Australia, Western Australia, the ACT, Adelaide and Hobart
signed the MoU with the Electric Vehicle Council.
The roundtable also agreed to pursue opportunities for
collaboration on policies to encourage energy efficiency in
buildings and suburbs and the infrastructure that supports them.
Roundtable members have a shared commitment to ambitious climate
change action consistent with the goals of the Paris Agreement.
In July they signed the Climate Leadership Declaration to
highlight the role states and territories can play in climate
change action and the economic benefits it can deliver.
Transport is the fastest-growing contributor to climate change
globally, and other major economies are moving away from petrol
and diesel-fuelled engines, climate change minister Ian Hunter
“It’s important that we are at the forefront of a transition to
lower-emission vehicles in Australia – both to reduce greenhouse
gases and other emissions, and to keep pace with global
Hunter says states, territories and cities have an important role
in increasing EV uptake as they control policies that can shift
public perception and behaviour.
Electric Vehicle Council chief executive officer Behyad Jafari
says the announcement is an encouraging step forward for
Australia, seeing state and local governments committing to work
together to drive progress on zero emissions transport.
“As the global market for electric vehicles grows exponentially,
Australia has fallen behind. We need governments to take
meaningful action to begin the process of transitioning our
economy from imported oils to transport run from domestically
generated renewable energy.
“I call on the remaining governments in Australia, particularly
the federal government, to hear this call and join us in
supporting a transition to a safer, healthier and cheaper road

Bill Thomas says it will do whatever is possible to support such
The company, along with Renault, Tesla, BMW, Audi, Mitsubishi and
Toyota, provided cars for the event.
This event was held in Victoria Square,
Adelaide, on the 1st of December 2017.
