Rolls-Royce acquires Siemens’ propulsion arm as it continues ‘electrification’ of business

Rolls-Royce has completed the acquisition of Siemens’ electric and hybrid-electric aerospace propulsion arm.

The deal was first announced in June and is the latest in a series of electrification announcements from Rolls-Royce.

At the end of August, it launched a joint research programme on zero-emissions aviation with Widerøe, the largest regional airline in Scandinavia. The programme is part of the airline´s ambition to replace and electrify its legacy regional fleet by 2030.

Siemens’s former business, based in Germany and Hungary, employs around 180 designers and engineers, who will continue to work in their existing locations.

Rob Watson, Director at Rolls-Royce Electrical, said: “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, and our new colleagues will add vital skills, expertise and new technology to our portfolio.”

Paul Stein, Rolls-Royce’s Chief Technology Officer, added: “The technology portfolio and skills that we have acquired complement our existing developments in electrification, which include micro-grids and hybrid electric trains as well as aerospace applications.”

“Electrification is just one of the ways in which we are making aviation more sustainable. We are continuing to increase the fuel efficiency of our gas turbines; increasing the integration between airframe and engine; and encouraging the development of sustainable fuels.”

Rolls-Royce previously worked alongside Siemens on the E-Fan X demonstrator programme. Rolls has also carried out ground tests of a hybrid propulsion system that can be used across a range of smaller transport platforms including EVTOLs, general aviation aircraft and hybrid helicopters.
