The future is electric

日本一本道最新高清无码Clean, sustainable, safe – that’s the promise of electric propulsion systems. It’s a promise made real by the technological advancements that make the use of electric systems technically and economically feasible.

We are championing electrification – developing, testing, and innovating technologies and systems together with partners to create the electric propulsion and energy systems of tomorrow.

It is these technological advances in power density and energy capacity of electric systems that will make the aerospace industry’s goal of actively limiting the environmental impacts of flight possible.

Propulsion

Welcome to the third era of aviation

日本一本道最新高清无码We have over 100 years of expertise supporting our next challenge: making electrification not just a concept, but a reality.

日本一本道最新高清无码(Hybrid-) electric drive systems allow aircraft to be powered by alternative fuels or electricity. They are silent, and, thanks to the separation of energy and thrust generation, allow for completely new aircraft designs. Electrification of aircraft bears the promise of more efficient, silent and sustainable flight; reducing fuel consumption and operating cost for aircraft operators.

Current regulations around carbon emissions and noise pollution, the high cost of fuel, and efficiency concerns make creating a replacement power source for aircraft urgent.

At the same time, technology advancements in power and energy density over the last years have brought electric solutions to a stage where they have become technically and economically feasible alternatives to existing aircraft propulsion systems.

The next revolution in power, electric flight, will allow us to achieve our carbon reduction targets and provide fliers with a new class of quieter and more environmentally friendly transport well into the next century.

Looking ahead to 2030 – when the International Air Transport Association (IATA) predicts there will be one billion more people on the planet, and six billion annual fliers – the case for championing electric aviation is clear.

Why we are championing electric flight

Air travel Demand

日本一本道最新高清无码Air travel demand is rising, stretching the limits of airports and our environment.

Environmental impact

Air transport’s CO2 emissions are rising 70% faster than predicted, with NOX emissions predicted to rise by 43% by 2035. Aircraft noise negatively affects humans and animals.

The time is now

Technological advancements have made electric flight technically and economically feasible

Efficiency

日本一本道最新高清无码Hybrid-electric propulsion systems can be more efficient than conventional propulsion. Moreover, separation of thrust and energy generation allows for more efficient aircraft designs.

Cost

It costs less to maintain an electric aircraft through reduced fuel costs. Hybrid-electric propulsion systems carry the potential of reduced fuel burn and operating cost. This makes it less costly to train pilots.

Extended operating hours

日本一本道最新高清无码Reduced noise will allow aircraft operations to be extended beyond the current limits.

Reshaping air travel

日本一本道最新高清无码More silent and economically efficient airplanes will allow new commuter concepts to offer transport services beyond the traditional flight routes. This has the potential to reinvigorate small regional airports and to make flight transport more accessible to large parts of society.

New mobility concepts

Electric propulsion systems are perfectly suited to power vertical take-off and landing vehicles. (Hybrid-) electric airtaxis can offer additional alternatives to urban traffic concepts, promising greener cities and convenient city transport.

Working to realise Europe’s vision for our environment

Key EU Flightpath 2050 targets:

  • Reduce CO2 emissions by 75% per passenger km Trent XWB Line and Base
  • Reduce NOX by 90%
  • Cut out perceived noise by 65%
  • Emission-free taxiing
What sustainable aviation will look like
To understand the revolutionary impact of electric power you need to rethink the way commercial and private aircraft take off, fly, and land.

日本一本道最新高清无码Electric power can support vertical takeoff and landing (eVTOL), and short take off and landings (STOL). This not only cuts down on noise and fuel, it means aircraft will be able to take off and land in cities and urban areas – quietly and emission-free.

Innovations that make sustainable aviation possible

Significant technological innovation has meant hybrid-electric technology has scaled several key hurdles in recent years.

POWER DENSITY

日本一本道最新高清无码Power density refers to how strong an engine is compared to how heavy it is. Electrical propulsion now compares well with combustion engines in terms of power density.

STORAGE ENERGY DENSITY

日本一本道最新高清无码Commercially available battery cells now allow flight times up to an hour, and this time is steadily increasing with continuing innovations in storage energy density.

FLIGHT CONTROL AUTONOMY AND SIMPLIFICATION

Making pilot certifications safer and easier requires both autonomous and simplified controls. Significant progress in both areas is smoothing the runway for market introduction, with the aim of making it less costly to certify future electric jet pilots.

"We believe pure electric, or all-electric, propulsion will power smaller aircraft in the foreseeable future- while larger aircraft will rely on hybrid electric solutions that combine electrification with evolutions of the gas turbine."

Future planes: 2020 and beyond

There are four primary markets hybrid-electric aviation will capture in the decade ahead.

Small two to four-seater planes

Hundreds of planes look set to be sold in the next few years to companies who use planes for training or sport. It will be the first time large segments of the public will see and experience electric flight. Small planes from ultralights all the way to the lower end of CS23, will play a key role in bringing the experience of electric flight to pilots.

Pioneering an electric tomorrow, today

With over a century of innovation-driven success behind us, and unparalleled industry knowledge and relationships, Rolls-Royce are well-equipped to create a bold new world of clean technology for the world’s growing population. We have extensive experience in electric and hybrid-electric applications across products within our three business units: Power Systems, Civil Aerospace, and Defence – all delivering fuel savings of between 15% and 50%.
