Rolls Royce Electric Plane | Speed 480+ kmph #eCharged
A group of companies led by Rolls-Royce plans to build the fastest all-electric propeller aircraft to date, capable of speeds in excess of 480 km / h by 2020.
The project also involves the manufacturer of electric motors and controllers YASA and the aviation startup Electroflight. The future prototype will be equipped with an energy-consuming battery, consisting of 6 thousand cells, three 750 kW electric motors and an active cooling system. Once launched, the propulsion system will operate at 750V and the three-blade propeller will be able to maintain 2400 RPM at 90% efficiency..
Enough charge for a non-stop flight from London to Paris. The key design element, Rolls-Royce says, will be a large, non-overheating battery that will be light enough to fly efficiently and fit in a small package. The project is being developed in the scope of the program «Progressive electrification of flight» (ACCEL), funded in part by the British government.
The single-seat prototype being created should become the leader of the third wave of aviation and may even be able to break the 1931 speed record of 552 km / h. Tests are planned to be carried out in 2020 at the Gloucestershire airfield. With the help of sensors, engineers will be able to track 20 thousand points in the transmission, obtaining all the necessary data on the performance of the device..
Another major global manufacturer HES Energy Systems also recently announced the development of its own version of the environmentally friendly flying vehicle. It will be an electric passenger aircraft powered by hydrogen fuel, which will be able to fly up to 5 thousand km..
