New Rolls-Royce electric plane takes first flight

Rolls-Royce

Rolls-Royce’s all-electric Spirit of Innovation aircraft took its first flight on 15th September, powered by the most power-dense battery pack ever assembled for an aircraft.

This is another step towards the 400kW electric aircraft's world-record attempt and another milestone on the aviation industry’s journey towards decarbonisation.

Warren East, CEO, Rolls-Royce, commented: “The first flight of the ‘Spirit of Innovation’ is a great achievement for the ACCEL team and Rolls-Royce. We are focused on producing the technology breakthroughs society needs to decarbonise transport across air, land and sea, and capture the economic opportunity of the transition to net zero. This is not only about breaking a world record; the advanced battery and propulsion technology developed for this programme has exciting applications for the Urban Air Mobility market and can help make ‘jet zero’ a reality.”

The aircraft took off from the UK Ministry of Defence’s Boscombe Down site, which is managed by QinetiQ and flew for approximately 15 minutes.

The site has a long heritage of experimental flights and the first flight marks the beginning of an intense flight-testing phase in which we will be collecting valuable performance data on the aircraft’s electrical power and propulsion system. The ACCEL programme, short for ‘Accelerating the Electrification of Flight’ includes key partners YASA, the electric motor and controller manufacturer, and aviation start-up Electroflight. The ACCEL team have continued to innovate while adhering to the UK Government’s social distancing and other health guidelines.

Half of the project’s funding is provided by the Aerospace Technology Institute (ATI), in partnership with the Department for Business, Energy & Industrial Strategy and Innovate UK.

“The first flight of the Spirit of Innovation demonstrates how innovative technology can provide solutions to some of the world’s biggest challenges,” said Gary Elliott, CEO, Aerospace Technology Institute. “The ATI is funding projects like ACCEL to help UK develop new capabilities and secure a lead in the technologies that will decarbonise aviation. We congratulate everyone who has worked on the ACCEL project to make the first flight a reality and look forward to the world speed record attempt which will capture the imagination of the public in the year that the UK hosts COP26.”

Rolls-Royce is offering customers a complete electric propulsion system for aircraft, whether that is an electric vertical takeoff and landing (eVTOL) or commuter aircraft. The engine maker we will be using the technology from the ACCEL project and applying it to products for these new markets.

The characteristics that ‘air-taxis’ require from batteries are very similar to what is being developed for the ‘Spirit of Innovation’ so that it can reach speeds of 300+mph, which Rolls-Royce is targeting in its world record attempt.

In addition, Rolls-Royce and airframer Tecnam are currently working with Widerøe, the largest regional airline in Scandinavia, to deliver an all-electric passenger aircraft for the commuter market, which is planned to be ready for revenue service in 2026.
