3 key areas of focus for product innovation in Civil Aerospace


4

These are all closely inter-connected and being developed in parallel within Rolls-Royce


Electrification is not new to Rolls-Royce


5

We have a wealth of experience in electric and hybrid electric applications across different business sectors.

Electrification is delivering a fuel saving of between 15% and 50%.


A growing Electrical global footprint


6

Also working with other partners and our network of UTCs

Siemens eAircraft


We have unique expertise and capability

Electrification brings challenges but we believe we are well placed to overcome these.

We are one of the few providers of total ‘energy source to thrust’ solutions

The ability to integrate mechanical, electrical and thermal systems

• Safety and certification

• Electro mechanical integration

• Thermal management & cooling

• Controls

Component technology

The ability to design high performance, high integrity components

• Lightweight, high power density

Electrification in Civil Aerospace

Partnership and collaboration are central to our approach

Evolutionary (incremental)

• More electric aircraft

• Electrical content increases –replacing mechanical and hydraulic systems

• Understanding of electrical technology becomes more important across the industry

• Platform level integration improves the technical attributes achievable

• Need to challenge legacy certification boundaries


8





9

Demonstrate the electrification of the BR engine family

• Imbedded generators

• Electric driven accessories

• Electric actuation systems

• Electric aircraft services





10

Revolutionary (disruptive)

• High number of demonstrators flying & planned

• New airframe and /or transport concepts creating new markets

• New entrants in the market

• Different scope of supply for incumbents

• Certification requirements in development

• Clear the path for electric and hybrid electric aircraft into service



11

How might we electrify our propulsion systems?


It’s about much more than the aircraft

Electrification could enable a shift in transport mode for civil aviation but innovative thinking is required right across our industry:

Transportation policies and subsidies

Physical and cyber security requirements

Digital ticketing

Airport design

Ground infrastructure and air traffic management

Regulatory requirements for certification and airworthiness

Potential single pilot operation

Mobility as a service


12



13

In summary

Electrification impacts all Civil Aerospace market segments

Our industry has committed to ambitious environmental targets

We are evolving incremental and disruptive solutions in parallel

Our journey is well underway and we have much to offer

Great progress so far but more radical architectures will be needed to meet FP2050

Technology maturity and demonstration at scale required

Gas turbine technology remains vital to our approach

A relatively small number of engine types required to address multiple opportunities

Championing Electrification as part of our corporate strategy

Partnering, collaborating and innovating on a number of projects

New regulatory requirements for certification need to be developed and agreed

Likely to bring opportunity and disruption for both market and product
