New Propulsion Technology from Rolls-Royce for Hybrid-Electric Flight
Rolls-Royce is developing turbogenerator technology which
includes a new small engine designed for hybrid-electric applications
to extend flight distances for aviation. The system will
be an on-board power source with scalable power offerings
and will complement the Rolls-Royce Electrical propulsion
portfolio, enabling extended range on sustainable aviation fuels
and later as it comes available through hydrogen combustion.
Current
battery technology
means all-electric
propulsion will enable
eVTOL and fixed wing
commuter aircraft for
short flights in and between
cities and islandhopping
in locations like
Norway and the Scottish
Isles. By developing turbogenerator technology that will be
scaled to serve a power range between 500 kW and 1200 kW,
it can open up new longer routes that electric battery powered
aircraft can also support.
Rolls-Royce experts based in Germany, Norway and Hungary
are developing the turbogenerator design and working on its
system integration with a focus on ensuring smart power distribution
during flight. The turbogenerator will recharge batteries
after take-off or power propellers directly, enabling aircraft
to switch between power sources in flight. The research and
development of this technology is being part funded by the
German Ministry for Economic Affairs and Climate Action.

" 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, " said Rob
Watson, president of Rolls-Royce Electrical
in announcing the program on June
22. " 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
of Rolls-Royce
Electrical
" 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. "
Last year, Rolls-Royce announced a pathway to net zero
carbon emissions and its electrical technology is one way in
which the company is helping decarbonize critical parts of the
global economy. Rolls-Royce is committed to ensuring its new
products will be compatible with net zero operation by 2030
and all its products will be compatible with net zero by 2050.
