Airbus, Rolls-Royce, and Siemens team up for E-Fan X hybrid-electric flight demonstrator

Friday, December 1, 2017

Paris: Airbus, Rolls-Royce, and Siemens have formed a partnership which aims at developing a near-term flight demonstrator which will be a significant step forward in hybrid-electric propulsion for commercial aircraft.

The three companies together announced the groundbreaking collaboration, bringing together some of the world’s foremost experts in electrical and propulsion technologies, at the Royal Aeronautical Society in London.

The E-Fan X hybrid-electric technology demonstrator is anticipated to fly in 2020 following a comprehensive ground test campaign, provisionally on a BAe 146 flying testbed, with one of the aircraft’s four gas turbine engines replaced by a two megawatt electric motor. Provisions will be made to replace a second gas turbine with an electric motor once system maturity has been proven.

“The E-Fan X is an important next step in our goal of making electric flight a reality in the foreseeable future. The lessons we learned from a long history of electric flight demonstrators, starting with the Cri-Cri, including the e-Genius, E-Star, and culminating most recently with the E-Fan 1.2, as well as the fruits of the E-Aircraft Systems House collaboration with Siemens, will pave the way to a hybrid single-aisle commercial aircraft that is safe, efficient, and cost-effective,” said Paul Eremenko, Airbus’ Chief Technology Officer. “We see hybrid-electric propulsion as a compelling technology for the future of aviation.”

The E-Fan X demonstrator will explore the challenges of 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 quick progress on the hybrid electric technology. The programme also aims at establishing the requirements for future certification of electrically powered aircraft while training a new generation of designers and engineers to bring hybrid-electric commercial aircraft one step closer to reality.

As part of the E-Fan X programme, Airbus, Rolls-Royce, and Siemens will each contribute with their extensive experience and know-how in their respective fields of expertise:
