Rolls Royce unveils Turbogenerator Technology for hybrid-electric propulsion. Here’s what’s new

Rolls Royce has now announced the development of turbogenerator technology, which includes a new small engine designed for hybrid-electric applications. Touted to expand the range of low-emission aircraft on sustainable aviation fuels, the system will be an on-board power source with scalable power offerings and will complement the Rolls-Royce Electrical propulsion portfolio.

How is it different from current battery technology?

 By developing turbogenerator technology, that will be scaled to serve a power range between 500 kW and 1200 kW, the company hopes of opening up new longer routes in comparison to current battery technology that enables only short eVTOL and fixed-wing commuter aircraft in and between cities and island-hopping in locations like Norway and the Scottish Isles.

Partly funded by the German Ministry for Economic Affairs and Climate Action, the research and development team based in Germany, Norway and Hungary are developing the turbogenerator design and working on its system integration while at the same time focussing on ensuring smart power distribution during flight.

Rolls-Royce will be the leading provider of all-electric and hybrid-electric power and propulsion systems for Advanced Air Mobility and will scale this technology over time to larger platforms. I would like to thank the German Government for their support. As part of our strategy, we are looking at offering the complete sustainable solution for our customers. This means extending routes that electric flight can support through our turbogenerator technology. This will advance hybrid-electric flight and mean more passengers will be able to travel further on low to net zero emissions aircraft

Rob Watson, President – Rolls Royce Electrical, said

The batteries will be recharged by the turbogenerator after take-off or power propellers directly, enabling aircraft to switch between power sources in flight.

Earlier this year, Rolls Royce collaborated with Roland Burger to release a market study into the potential of the AAM market for the APAC region- consisting of Australia, China, India, Japan, Singapore, South Korea and New Zealand.

Rolls-Royce is also set to build on our existing network to offer maintenance services for electrical systems. Furthermore, Rolls-Royce Power Systems is able to offer mtu microgrid solutions to support fast-charging of electric aircraft and deliver reliable, cost-effective, climate friendly and sustainable power to vertiports

Reportedly, Rolls Royce had also said it would team up with Luxaviation Group on the development of a planned network of vertiports. The company has also committed to ensuring all new products will be compatible with net-zero emissions operation by 2030, and the entire range of products will be compatible with net-zero by 2050.
