Rolls-Royce and Tecnam to deliver an all-electric passenger aircraft in 2026

Rolls-Royce and airframer Tecnam are joining forces with Widerøe – the largest regional airline in Scandinavia, to deliver an all-electric passenger aircraft for the commuter market, ready for revenue service in 2026. The project expands on the successful research programme between Rolls-Royce and Widerøe on sustainable aviation and the existing partnership between Rolls-Royce and Tecnam on powering the all-electric P-Volt aircraft.

Stein Nilsen, Chief Executive, Widerøe said: “Norway’s extensive network of short take-off and landing airports is ideal for zero emissions technologies. This aircraft shows how quickly new technology can and will be developed, and that we are on track with our ambition of flying with zero emissions around 2025.”

Rob Watson, Director – Rolls-Royce Electrical, said: “Electrification will help us deliver our ambition to enable the markets in which we operate achieve net zero carbon by 2050. This collaboration strengthens our existing relationships with Tecnam and Widerøe as we look to explore what is needed to deliver an all-electric passenger aircraft for the commuter market. It also demonstrates Rolls-Royce’s ambitions to be the leading supplier of all-electric and hybrid electric propulsion and power systems across multiple aviation markets.”

The programme will look to cover all elements of developing and delivering an all-electric passenger aircraft that could be used in the Norwegian market from 2026. Due to its topography, Norway makes extensive use of aviation for regional connectivity and has an ambition for all domestic flights to be zero emissions by 2040. Rolls-Royce will bring its expertise in propulsion and power systems, Tecnam will provide aircraft design, manufacturing and certification capabilities. Widerøe’s mission will be to ensure that all competence and requirements of an airline operator are in place for entry into service in 2026.

Andreas Aks, Chief Strategy Officer, Widerøe, added: “We are highly excited to be offered the role as launch operator, but also humble about the challenges of putting the world’s first zero emissions aircraft into service. Our mission is to have all new capabilities, processes and procedures required for a zero emissions operator, designed and approved in parallel with the aircraft being developed and certified.”

Fabio Russo, Chief Project R and D and Product Development, Tecnam, said: “It is incredible to see the interest around the P-Volt, not only coming from regional airlines, but also from smart mobility-based companies. This last year has demonstrated the importance of promoting capillary connections between small communities, while reducing the congestion of the main hubs. The P-Volt, like the P2012 Traveller today, will perfectly fit the scope of this programme. We are honoured and pleased to see the level of enthusiasm Widerøe and our partner Rolls-Royce are dedicating to this project.”

The collaboration offers an opportunity to develop an exciting solution to the commuter aircraft market. Before the pandemic, Widerøe offered around 400 flights per day using a network of 44 airports, where 74% of the flights have distances less than 275 km. The shortest flight durations are between seven and fifteen minutes. Developing all-electric aircraft will enable people to be connected in a sustainable way and will fulfill Wideroe’s ambition to make its first all-electric flight by 2026. The all-electric P-Volt aircraft, which is based on the 11-seat Tecnam P2012 Traveller aircraft is ideal for the short take-off and landing as well as for routes in the North and the West Coast of Norway.

Rolls-Royce and Widerøe announced a joint research programme in 2019. The aim of the programme was to evaluate and develop electrical aircraft concepts that would fulfil the Norwegian ambition of having the first electrified aircraft in ordinary domestic scheduled flights by 2030 and 80% emission reduction in domestic flights by 2040.

Rolls-Royce also has an existing strategic partnership with Tecnam to develop the modified Tecnam P2010 aircraft with the H3PS1 propulsion system, the first parallel hybrid-electric propulsion system for General Aviation started together with Rotax in May 2018.

Rolls-Royce develop embedded starter-generator for next-generation fighter jet

Over the last five years Rolls-Royce has been pioneering world-first technology that will contribute to the UK’s next-generation Tempest programme.

In an aim to be more electric, more intelligent and to harness more power, Rolls-Royce recognised that any future fighter aircraft will have unprecedented levels of electrical power demand and thermal load; all needing to be managed within the context of a stealthy aircraft.

Before the launch of the Tempest programme, Rolls-Royce had already started to address the demands of the future. Back in 2014, the company took on the challenge of designing an electrical starter generator that was fully embedded in the core of a gas turbine engine, now known as the Embedded Electrical Starter Generator or E2SG demonstrator programme.

Conrad Banks, Chief Engineer for Future Programmes at Rolls-Royce said: “The electrical embedded starter-generator will save space and provide the large amount of electrical power required by future fighters. Existing aircraft engines generate power through a gearbox underneath the engine, which drives a generator. In addition to adding moving parts and complexity, the space required outside the engine for the gearbox and generator makes the airframe larger, which is undesirable in a stealthy platform.”

Phase two of this programme has now been adopted as part of Rolls-Royce’s contribution to the Tempest programme.

As part of this journey, the company has been continuously developing its capabilities in the aerospace market, from gas turbine technologies through to integrated power and propulsion systems. The goal being to provide not only the thrust that propels an aircraft through the sky, but also the electrical power required for all the systems on board as well as managing all the resulting thermal loads.

Rolls-Royce is adapting to the reality that all future vehicles, whether on land, in the air or at sea will have significantly increased levels of electrification to power sensors, communications systems weapons, actuation systems and accessories, as well as the usual array of avionics.

The launch of phase one of the E2SG programme saw significant investment in the development of an integrated electrical facility – a unique test house where gas turbine engines can be physically connected to a DC electrical network.

The launch of the second phase of the project in 2017 saw the inclusion of a second electrical generator connected to the other spool of the engine. It also included an energy storage system in the electrical network and the ability to intelligently manage the supply of power between all these systems.

The two-spool mounted electrical machines allows, by combination of operation as either a motor or a generator, the production of a series of functional effects on the engine, including the transfer of power electrically between the two spools.

As part of the E2SG programme, Rolls-Royce is investigating the feasibility of using dual spool generation to influence the operability, responsiveness and efficiency of the engine. Another key technology under development is the Power Manager intelligent control system, which uses algorithms to make real time intelligent decisions about how to supply the current aircraft electrical demand while optimising other factors including engine efficiency to reduce fuel burn or engine temperature to extend component life.

Throughout the Tempest programme, Rolls-Royce will be continuing to mature the electrical technologies demonstrated by the E2SG programme, with a third phase of testing likely to include a novel thermal management system being integrated with the overall system, as well as more electric engine accessories.

The company also intends to showcase a full-scale demonstrator of an advanced power and propulsion system. There will be new technologies in all parts of the gas turbine, including twin spool embedded generation to higher power levels, an advanced thermal management system, an energy storage system tailored to the expected duty cycle of the future fighter and an intelligent power management system which will be able to optimise the performance of both the gas turbine and the power and thermal management system.

Airbus, Rolls-Royce, and Siemens team up for electric aircraft

Airbus, Rolls-Royce, and Siemens have formed a partnership which aims at developing a near-term flight demonstrator which will be a significant step forward in hybrid-electric propulsion for commercial aircraft.

The three companies together announced the groundbreaking collaboration, bringing together some of the world’s foremost experts in electrical and propulsion technologies, at the Royal Aeronautical Society in London.

The E-Fan X hybrid-electric technology demonstrator is anticipated to fly in 2020 following a comprehensive ground test campaign, provisionally on a BAe 146 flying testbed, with one of the aircraft’s four gas turbine engines replaced by a two megawatt electric motor. Provisions will be made to replace a second gas turbine with an electric motor once system maturity has been proven.

“The E-Fan X is an important next step in our goal of making electric flight a reality in the foreseeable future. The lessons we learned from a long history of electric flight demonstrators, starting with the Cri-Cri, including the e-Genius, E-Star, and culminating most recently with the E-Fan 1.2, as well as the fruits of the E-Aircraft Systems House collaboration with Siemens, will pave the way to a hybrid single-aisle commercial aircraft that is safe, efficient, and cost-effective,” said Paul Eremenko. “We see hybrid-electric propulsion as a compelling technology for the future of aviation.”

The E-Fan X demonstrator will explore the challenges of high-power propulsion systems, such as thermal effects, electric thrust management, altitude and dynamic effects on electric systems and electromagnetic compatibility issues. The objective is to push and mature the technology, performance, safety and reliability enabling quick progress on the hybrid electric technology. The programme also aims at establishing the requirements for future certification of electrically powered aircraft while training a new generation of designers and engineers to bring hybrid-electric commercial aircraft one step closer to reality.

Paul Stein, Rolls-Royce, Chief Technology Officer, said: “The E-Fan X enables us to build on our wealth of electrical expertise to revolutionise flight and welcome in the third generation of aviation. This is an exciting time for us as this technological advancement will result in Rolls-Royce creating the world’s most powerful flying generator.

“Siemens has been driving innovation in core technology fields at full speed,” said Roland Busch, Chief Technology Officer of Siemens. “In April 2016 we opened a new chapter in electric-mobility with the collaboration with Airbus. Building up electric propulsion for aircraft, we are creating new perspectives for our company and also for our customers and society. With the E-Fan X partnership, we now take the next step to demonstrate the technology in the air.”

Among the top challenges for today’s aviation sector is to move towards a means of transport with improved environmental performance, that is more efficient and less reliant on fossil fuels. The partners are committed to meeting the EU technical environmental goals of the European Commission’s Flightpath 2050 Vision for Aviation (reduction of CO2 by 60%, reduction of NOx by 90% and noise reduction by 75%). These cannot be achieved with the technologies existing today. Therefore, Airbus, Rolls-Royce and Siemens are investing in and focusing research work in different technology areas including electrification. Electric and hybrid-electric propulsion are seen today as among the most promising technologies for addressing these challenges.

Rolls-Royce says Plug-In hybrid ‘essential’ in two years

Rolls-Royce now looks likely to adopt plug-in hybrid technology within the next three years. Chief Torsten Müller-Otvos told Auto Express at the Geneva show that “It will be essential in two years, maybe not from customer demand but through legal regulation on emissions”

With parent company BMW already working on plug-in hybrid technology that is soon to be launched on the X5 eDrive – which uses a four-cylinder turbo paired with an electric motor – Rolls-Royce could soon have access to such a powetrain. Müller-Otvos said: “We are now a completely self-sustaining business, but technology like this is so expensive to develop that without BMW, Rolls-Royce would probably not have survived.”
