Coming soon: the future of electric flight

A true world-first, ACCEL is scheduled to take to the skies over Great Britain in 2020. ACCEL is designed to reach a speed of 300 mph and more – it will be the fastest all-electric plane in history.

Our partners in pioneering all-electric aviation

This ground-breaking project is made possible by collaborating with the UK’s finest experts in the field, along with support from the UK Government.


 

Rolls-Royce and YASA

Rolls-Royce is working with (UK), a manufacturer of high-power, lightweight electric motors and controllers used in automotive, aerospace and industrial applications.

"We’re excited to be working with Rolls-Royce on integrating our high-power, light weight electric motors into a pure electric demonstrator aircraft. Thanks to our innovative axial-flux design, YASA can deliver the smallest, lightest electric motors for a given power and torque – opening up new and exciting opportunities for electrification in aerospace."
Chris Harris, CEO, YASA


 

Rolls-Royce and Electroflight

Rolls-Royce is supported by (UK), a start-up specialising in high performance electric powertrains.

"We are delighted to be supporting Rolls-Royce with an integrated electric powertrain including an innovative energy storage solution. Our team comprises leading experts in electrification from the motorsport and automotive sector to assist our partners to accelerate the evolution of electric aircraft."
Roger Targett, Managing Director, Electroflight


 

The challenge is on

Creating the fastest all-electric aircraft was never going to be done overnight. There are unique challenges to overcome. The battery will need to be powerful enough to beat a series of speed and performance records, light enough to fly, and stable enough not to overheat.

To ensure the project’s success we are monitoring more than 20,000 data points per second and measuring battery voltage and temperature. We are also monitoring the overall health of the powertrain, which is responsible for powering the propellers and generating thrust.

"We’re gaining the know-how to not only pioneer the field of electric-powered, zero-emissions aviation - but to lead it. At this point, our confidence is sky high."

The technology that powers ACCEL

ACCEL has the most energy-dense battery pack ever assembled for an aircraft. It can provide enough power to fly 200 miles (London to Paris) on a single charge.

日本一本道最新高清无码Its 6,000 cells are packaged for maximum lightness and thermal protection. An advanced cooling system can withstand the extreme temperatures and high-current demands during flight.
