Rolls-Royce acquires Siemens’ eAircraft business
British multinational Rolls-Royce has announced the acquisition of the electric and hybrid-electric aerospace propulsion activities of Germany’s Siemens.
With around 180 designers and engineers based in Germany and Hungary, Siemens eAircraft business have been developing all-electric as well as hybrid electric propulsion solutions.
Rob Watson, director of 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.”
The acquisition comes after an existing collaboration with the eAircraft team on the E-Fan X demonstrator project, regarding hybrid electric propulsion for regional aircraft. Rolls-Royce said it would continue to work with Siemens to support CO2 reduction goals.
“To support the rising demand for air travel while achieving CO2 emissions targets, the aviation industry is developing increasingly environmentally friendly technologies and practices,” said Paul Stein, Rolls-Royce Chief Technology Officer. “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.”
Siemens: Providing the First Industrial 5G Router
Across a number of industry sectors, there’s a growing need for both local wireless connectivity and remote access to machines and plants. In both of these cases, communication is, more often than not, over a long distance. Public wireless data networks can be used to enable this connectivity, both nationally and internationally, which makes the new 5G network mainframe an absolutely vital element of remote access and remote servicing solutions as we move into the interconnected age.
Siemens Enables 5G IIoT
The eagerly awaited Scalance MUM856-1, Siemens’ very first industrial 5G router, is officially available to organisations. The device has the ability to connect all local industrial applications to the public 5G, 4G (LTE), and 3G (UMTS) mobile wireless networks ─ allowing companies to embrace the long-awaited Industrial Internet of Things (IIoT).
The router can be used to remotely monitor and service plants, machines, as well as control elements and other industrial devices via a public 5G network ─ flexibly and with high data rates. Something that has been in incredibly high demand after being teased by the leading network providers for years.
Scalance MUM856-1 at a Glance
- Scalance MUM856-1 connects local industrial applications to public 5G, 4G, and 3G mobile wireless networks
- The router supports future-oriented applications such as remote access via public 5G networks or the connection of mobile devices such as automated guided vehicles in industry
- A robust version in IP65 housing for use outside the control cabinet
- Prototypes of Siemens 5G infrastructure for private networks already in use at several sites
“To ensure the powerful connection of Ethernet-based subnetworks and automation devices, the Scalance MUM856-1 supports Release 15 of the 5G standard. The device offers high bandwidths of up to 1000 Mbps for the downlink and up to 500 Mbps for the uplink – providing high data rates for data-intensive applications such as the remote implementation of firmware updates. Thanks to IPv6 support, the devices can also be implemented in modern communication networks.
Various security functions are included to monitor data traffic and protect against unauthorised access: for example, an integrated firewall and authentication of communication devices and encryption of data transmission via VPN. If there is no available 5G network, the device switches automatically to 4G or 3G networks. The first release version of the router has an EU radio license; other versions with different licenses are in preparation. With the Sinema Remote Connect management platform for VPN connections, users can access remote plants or machines easily and securely – even if they are integrated in other networks. The software also offers easy management and autoconfiguration of the devices,” Siemens said.
Preparing for a 5G-oriented Future
Siemens has announced that the new router can also be integrated into private 5G networks. This means that the Scalance MUM856-1 is, essentially, future-proofed when it comes to 5G adaptability; it supports future-oriented applications, including ‘mobile robots in manufacturing, autonomous vehicles in logistics or augmented reality applications for service technicians.’
And, for use on sites where conditions are a little harsher, Siemens has given the router robust IP65 housing ─ it’s “dust tight”, waterproof, and immersion-proofed.
