The team behind Rolls-Royce is developing an electric aircraft known as ACCER, which aims at a speed of 480 km / h in 2020.

Shortened by “Accelerating Electrification of Flight”, ACCEL seeks to become the fastest electric aircraft in history and exploits the expertise from the world of Formula E to achieve this. The project, which includes both the manufacturer of the electric motor and the YASA controller and the Electroflight airplane launch, will be based on the Hangar at Gloucestershire Airport. According to Rolls, single-seat propulsion aircraft will carry the most powerful battery ever and will have a range of 200 miles or 322 km.

“This aircraft is powered by the most modern electrical system and the most powerful battery ever made for the flight,” said Matheu Parr, Accelerator Manager at Rolls-Royce. “In the upcoming year we will show his capabilities in demanding test environments before 2020. We go for gold from the Wales airport.

A full electric drive will provide a maximum power of 750 volts with an efficiency of over 90 percent. The Propel will operate three 750R high power engines designed and manufactured by YASA in the UK. Together they will provide more than 500 horsepower when ACCEL takes over the record in the next year. Large data will also play a key role in optimizing security and performance, with thousands of data points being monitored in real time.

“Keep track of more than 20,000 data points per second, by measuring the battery voltage, temperature and overall health of the drive circuit, which is responsible for propeller power and thrust generation,” Parr said.

“We’ve already drawn a series of insights into unique design and integration challenges, and we are getting the knowledge of not only pioneering the area of ​​electric, zero air emissions – but guiding it.”

The current record for a fully electric plane is 210 km / h and Siemens has set it up in 2017. In addition, the ACCEL team also has a design at 343 km / h reaching Supermarine S.6B with Rolls Drive in 1931. a performance that Britain won the Schneider Trophy award of that year. Hidroavion S.6B will continue to inform Supermarine Spitfire, one of the most famous combat aircraft of World War II.
