Rolls-Royce set to land Siemens electric planes division

Rolls-Royce is set to buy the the electric and hybrid-electric aerospace propulsion activities of Siemens.

Rolls-Royce says the deal will accelerate the delivery of its electrification strategy and boost its ambition to play a major role in the ‘third era’ of aviation.

The deal is expected to complete late 2019, following a period of employee consultation.

Siemens’ eAircraft business, based in Germany and Hungary, employs around 180 specialist electrical designers and engineers who have been developing a range of all-electric and hybrid electric propulsion solutions for the aerospace industry. The eAircraft team are already known to Rolls-Royce as we have worked together on the E-Fan X demonstrator project which, when flying, will demonstrate hybrid electric propulsion at the scale required to power regional aircraft.

Rob Watson, director – Rolls-Royce Electrical, said: “Electrification is set to have as dramatic an impact on aviation as the replacement of piston engines by gas turbines. We are at the dawn of the third era of aviation, which will bring a new class of quieter and cleaner air transport to the skies.”

“We have already made significant strides in realising our strategy of ‘championing electrification’ and this move will accelerate our ambitions in aerospace by adding vital skills and technology to our portfolio. It brings us increased scale and additional expertise as we develop a product range of hybrid power and propulsion systems. I look forward to welcoming our new colleagues into Rolls-Royce and working with them to pioneer new technologies and solutions.”

Paul Stein, Rolls-Royce chief technology officer, added: “To support the rising demand for air travel while achieving CO2 emissions targets, the aviation industry is developing increasingly environmentally friendly technologies and practices. The electrification of flight is just one part of Rolls-Royce’s commitment to making aviation more sustainable: we are continuing to increase the fuel efficiency of our gas turbines; encouraging the development of environmentally friendly and sustainable aviation fuels; and pursuing the electrification of aviation.”

“We believe that pure electric, or all-electric, propulsion will power smaller aircraft in the foreseeable future, while larger aircraft will rely upon hybrid electric solutions that combine electrification with evolutions of the gas turbine. Additionally, as our group technological portfolio becomes increasingly electrical with the development of hybrid electric trains and microgrids, the capabilities of this world-class team will be a vital part of the future Rolls-Royce.”

As part of this agreement, Rolls-Royce says it will look for opportunities to work with Siemens as both companies “recognise the importance of helping to support national and international goals of CO2 emission reductions for the benefit of society”.
