Electric aircraft roadmapToward silent, CO2-free flight

E-Fan is a key element in Airbus’ electric aircraft roadmap, with the goal of achieving emission-free quiet flight. The Company is targeting advanced technological breakthroughs that could be key enablers of its long-term goal to ‘electrify the skies.’

The Airbus Innovations research and technology network is leading a company-wide electric aircraft roadmap. This strategy outlines a step-by-step approach for Airbus’s short-, medium- and long-term development of electric planes.

We are focusing on taking the experience gained with the E-Fan demonstrator aircraft, continuing our evaluations, and applying this knowledge for the serial production of E-Fan – and beyond.

E-Fan 2.0 sets the stage for the roadmap’s product development plan, one of its two key pillars, which ranges from serial E-Fan production to long-term goals such as a potential hybrid-electric regional airliner or helicopter.

Technology improvements across different products

The product strategy is closely supported by the roadmap’s other component – the concurrent development of ground and flying demonstrators to evaluate the feasibility and benefits of e-aircraft technology. 

This activity is led by Airbus’s E-Aircraft System House and covers research on a wide range of disruptive technologies and programmes, along with collaborative projects. The knowledge and expertise gained will enable improvements across the Group’s product range, including more on-board electrical power to increase aircraft efficiency, reduce noise and lower emissions.

The E-Aircraft System House will serve as a resource for the entire Airbus.

A central hub for electric aviation in Munich

The E-Aircraft System House is at the heart of Airbus’s electric aircraft activities. This large test and development facility near Munich, Germany will serve as an Airbus focal point to validate electric and hybrid aircraft propulsion technologies.

To reach the necessary levels of maturity for e-aircraft technology, the E-Aircraft System House is initially focusing on:

  • Advancing basic technological expertise and capabilities for individual components
  • Investigating incorporation of components into sub-systems such as electric fans and propellers, high-voltage platforms, turbines, generators and thermal systems

Ground was officially broken on the facility in Spring 2016 – which will enable the start of construction in early 2017 and a planned opening by late 2018. The site will be jointly operated by the Airbus Innovations research and technology network and the Group’s three divisions: Airbus, Airbus Helicopters and Airbus Defence and Space. 

Advancing Europe’s innovation in electric aircraft

Another important part of the company’s electric aircraft roadmap is teaming with world-class partners to investigate disruptive innovations. 

One example with this is the Group’s collaboration agreement with Siemens to demonstrate the technical feasibility of hybrid/electric propulsion systems by 2020. With the goal of advancing European leadership in electric aircraft technologies, both companies are making significant contributions and will create a team of around 200 people for the project.

Airbus and Siemens plan to jointly develop prototypes for various propulsion systems in three general power categories: 

  • Several hundred kilowatts, for applications such as helicopters and unmanned aerial vehicles (UAVs)
  • Up to two megawatts, typically applicable to intra-urban air vehicles
  • Ten megawatts up to 20 megawatts for regional passenger aircraft.
Siemens and Airbus have signed a cooperation agreement to advance e-mobility for aircraft.
