Rolls-Royce ground tests of the fastest electric aircraftSeptember 29, 2020
It was revealed last year that Rolls-Royce is developing the fastest electric aircraft. The company has now announced that ground testing of the technology has been completed and the vehicle is ready to take to the skies.
Late last year Rolls-Royce unveiled the ionBird, a single-seat prototype aircraft capable of speeds of up to 480 km / h. It is being developed as part of the ACCEL project in partnership with electric motor manufacturer YASA and the aviation startup Electroflight.
The aircraft is equipped with an electric propulsion system, which the company has previously tested on the ionBird test model. Three powerful electric motors will generate 750 kW and provide the aircraft with a flight range of 320 km on a single charge of a 6,000-cell battery. According to Rolls-Royce, the aircraft’s top speed will be over 480 km / h.
The technology was recently tested on a full size ionBird mockup. The company’s engineers accelerated the propeller to a speed of about 2400 rpm, checked the system performance, collected data for further analysis, writes New Atlas.
At the end of the year, ACCEL is to make its first flight, during which, as promised by Rolls-Royce, it will definitely set a speed record.
Last summer, Rolls-Royce said it was looking to regain its position as a turboprop manufacturer due to layoffs and quality problems, but the chance for the company could be to pivot the aviation industry towards electric and hybrid engines.
