Rolls Royce is telling global aviation officials that its new all-electric aircraft is the fastest such plane in the world at almost 390 miles per hour.
The British company’s “Spirit of Innovation” topped out at the purportedly record extended pace of 345.5 over three kilometers just last week, according to the release. Rolls Royce submitted its data to the global Federation Aeronautique Internationale to bolster an verify its claim.
At one point during the test run in United Kingdom skies, the Spirit of Innovation hit 387 miles per hour which, if verified, would achieve the fastest velocity for an all-electric aircraft, according to reports.
“Staking the claim for the all-electric world-speed record is a fantastic achievement for the ACCEL team and Rolls-Royce,” company CEO Warren East said in a statement. “The advanced battery and propulsion technology developed for this program has exciting applications for the Advanced Air Mobility market… this is another milestone that will help make ‘jet zero’ a reality and supports our ambitions to deliver the technology breakthroughs society needs to decarbonize transport across air, land and sea.”
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 is propelled by a 400kW (500+hp) electric powertrain. Rolls Royce and the ACCEL team worked with aviation energy storage firm Electroflight and automotive powertrain supplier YASA.
The speed run comes only two months of the Spirit of Innovation’s maiden voyage. The electric aircraft also reportedly took less than four minutes to reach nearly 9,000 feet altitude, according to reports.
The Spirit of Innovation’s battery, located in the front half of the airplane body, has 6,480 cells, enough to charge 7,500 phones. The craft’s system voltage is 750 volts, while the motor power is 400 kW.
Portuguese cork is used to insulated the battery heat.
The control and piloting system are near the rear of the plane right in front of the tail section..
