“We believe our all-electric Spirit of Innovation aircraft is the world’s fastest all-electric aircraft, setting three new world records. We have submitted data to the Fédération Aéronautique Internationale (FAI) – the World Air Sports Federation who control and certify world aeronautical and astronautical records – that at 15:45 (GMT) on 16 November 2021, the aircraft reached a top speed of 555.9 km/h (345.4 mph) over 3 kilometres, smashing the existing record by 213.04 km/h (132mph). In further runs at the UK Ministry of Defence’s Boscombe Down experimental aircraft testing site, the aircraft achieved 532.1km/h (330 mph) over 15 kilometres – 292.8km/h (182mph) faster than the previous record – and broke the fastest time to climb to 3000 metres by 60 seconds with a time of 202 seconds, according to our data. We hope that the FAI will certify and officially confirm the achievements of the team in the near future,” Rolls-Royce said in a statement.
During its record-breaking runs, the aircraft clocked up a maximum speed of 623 km/h (387.4 mph) which we believe makes the Spirit of Innovation the world’s fastest all-electric vehicle.
The Spirit of Innovation is part of the ACCEL or Accelerating the Electrification of Flight project. 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 aircraft was propelled on its record breaking runs by a 400kW (500+hp) electric powertrain and the most power-dense propulsion battery pack ever assembled in aerospace. We worked in partnership with aviation energy storage specialist Electroflight and automotive powertrain supplier YASA. As well as a stunning technical achievement, the project and world record runs provided important data for our future electric power and propulsion systems for all-electric urban air mobility and hybrid-electric commuter aircraft. The characteristics that ‘air-taxis’ require from batteries, for instance, are very similar to what was developed for the Spirit of Innovation.
Rolls-Royce has an incredible history of flying speed record attempts and breaking records, dating back to the Schneider Trophies of the early 1930s. The speed achieved by test pilot and Rolls-Royce Director of Flight Operations Phill O’Dell in the Spirit of Innovation was more than 213.04 km/h (132 mph) faster than the previous record set by the Siemens eAircraft powered Extra 330 LE Aerobatic aircraft in 2017. Never in the history of the FAI record attempts has there been such a significant increase in speed over such a short time, highlighting the rapid pace at which electrification of aerospace is advancing.
