Rolls-Royce Takes Milestone with Revolutionary New Engine System: “Next Generation” | Sciences | News

The British engineering giant’s new hybrid-electric propulsion system is being developed so that future airliners can fly low-carbon planes. Rolls-Royce has announced that it has generated more than one megawatt (1 MW) of power during ground tests. The next step is to reach 2.5 MW, with further testing expected to continue at the company’s refurbished 108 test bench facility.

Plan to make net-zero propulsion engines and electric flight possible is among critical pillars needed to decarbonize the aviation industry

He will see Britain’s emissions cut as it seeks to become carbon neutral by 2050.

Rolls-Royce Technical Director Paul Stein told about the three pillars of sustainable aviation.

He said, “We make sure that all of our existing products that we manufacture and that we know will be part of our future are net zero compatible.

“Aviation is still seen as a difficult sector to decarbonize, and as a business we believe it is difficult to decarbonize, but all sectors are difficult to decarbonize and there is no silver bullet behind it. anything and we try to help all sectors as much as possible.

“The first pillar is to make our engines more and more efficient, because whatever happens, the less emissions, the better.

“At Rolls-Royce, one of our big contributions to this is our technology called ultrafan, the next generation of big engines that are designed to be 10 percent fuel efficient over our previous engines, and very importantly, are designed to be 100 percent compatible. with ready-to-use sustainable aviation fuels.

Mr Stein said the ultrafans will work as a net zero propulsion system for an aircraft.

Adam Newman, Rolls-Royce’s chief project engineer for the future of aviation, said of the new hybrid electric motor: “When future hybrid electric aircraft opportunities emerge in the megawatt and above class, we want to be as prepared as possible. offer a ready-made solution. “

But after being successful in the field, there is yet another pillar needed to achieve net zero flight.

Mr. Stein explained the importance of stimulating the production of sustainable aviation fuels.

“You can see how this technology can create a whole new way for people to travel and it’s not just for the rich because they’re designed to be pretty inexpensive. “

Rolls-Royce said its PG21 generator technology could be used in hybrid electric propulsion systems or as part of a “more electric” system for larger planes.

For the final tests, the company combined a generator with the 3,000-volt power electronics that it tested at its plant in Trondheim, Norway.
