Rolls-Royce recently reached another key milestone in
its UltraFan technology demonstrator programme, as the power gearbox (PGB)
was dispatched from the company’s
site in Dahlewitz, Germany.
The power gearbox, which has set a world aerospace
power record in testing, was shipped to the UK where the first UltraFan engine demonstrator (UF001) is being assembled.
UltraFan offers a step change in gas turbine
sustainability, saving 25% fuel compared with the first generation
of Rolls-Royce Trent engines. Critical to that performance is the
PGB, which has a planetary design and can transmit more power than
an entire grid of Formula 1 cars when running at maximum power.
Rolls-Royce technology is making aviation more sustainable.
test it has delivered 87,000 horsepower, or 64 megawatts, enough
to power a medium-sized city.
The engine demonstrator, the largest engine in
the world with a fan diameter of 140 inches, will go on test in
Derby, England, this year and its first run will be on 100% Sustainable
Chris Cholerton, President of Rolls-Royce Civil
Aerospace, said, “This is a tremendous moment for everyone on the UltraFan programme as we take another step forward with the
dispatch of the power gearbox. I’m proud that we are creating
better, more efficient gas turbines which will be an essential
part of air travel for decades to come.”
UltraFan, scalable for narrowbody and widebody aircraft, is a key element of Rolls-Royce’s commitment to
making aviation more sustainable. Gas turbines will continue to be
the bedrock of long-haul aviation for many years, and UltraFan’s
efficiency will help improve the economics of an industry
transition to more sustainable aviation fuels, which are likely to
be more expensive than traditional jet fuel in the short-term.
