Rolls-Royce announced that its Spirit of Innovation electric aircraft has completed his first flight successfully. The aircraft & egrave; took off from the British Ministry of Defense's Boscombe Down site and flew for approximately 15 minutes . The success of this flight, explains Rolls-Royce, marks the beginning of a long test phase in which valuable data on the propulsion system and energy management will be collected.
in addition, another step towards the attempt at world speed record for an electric aircraft. Spirit of Innovation (a single-seater aircraft), was presented at the end of 2019 for this very purpose (target exceeding 480 km/h). This aircraft is part of the ACCEL program, short for Accelerating the Electrification of Flight. When the project was unveiled, it was said that the record attempt would take place in the spring of 2020. A goal that has been achieved; proved too ambitious. At the moment, it is not; a new date has been communicated on which an attempt will be made; the speed record.
Other partners involved in the ACCEL program are the electric motor manufacturer Yasa and the startup Electroflight. The project & egrave; co-funded by the Aerospace Technology Institute (ATI) and the UK Government. The aircraft's propulsion system is composed of three electric motors capable of delivering a total of 400 kW , according to Rolls-Royce. No precise details have been communicated on the battery pack used. In the past it was only reported that it consisted of 6,000 cells. The technology that will be tuning will be & agrave; later used on other projects as well.
For example, Rolls-Royce and Tecnam are currently working with Wider & oslash; e, the most & ugrave; Scandinavia's largest regional airline, to build a fully electric passenger aircraft which is expected to enter service in 2026. Warren East , CEO of Rolls-Royce, on the success of this test flight, said:
The first flight of the Spirit of Innovation & egrave; a great result for the ACCEL team and Rolls-Royce. We are focused on the development of the technological innovations of which the company & agrave; needs to decarbonise air, land and sea transport and seize the opportunity; economic of this transition. It's not just about breaking a world record; the technological evolution of the batteries and propulsion developed for this program has interesting applications for the mobility market; urban aerial.
