Rolls-Royce has completed testing of its revolutionary technology that will power the world's fastest all-electric aircraft. With its 500 horsepower motor and a revolutionary battery, the device could exceed 480 km / h.
After the development of the airframe, here is that of the electric motor of the aircraft of(Accelerating the Electrification of Flight) from Rolls-Royce. The manufacturer has just completed full-scale tests of the racing aircraft's powerful electric motor. To test it, Rolls-Royce attached it to the engine mount of a replica of the aircraft's airframe.
Thedevelops unparalleled power of 500 horsepower. With him, the firm intends to beat the speed record in by making it evolve at more than 480 km / h. During testing, the propeller was successfully brought to full throttle with around 2,400 rpm. To run the engine, a powerful, very dense battery made up of 6,000 cells is at work.
Objective: zero carbon emissions by 2050
As in aviation, the constraints are important; it's on thisthat lies most of the innovation. It must be as light as possible and also have an efficient thermal protection and cooling system. A real challenge for the manufacturer as well as for the future of electric aviation. Rolls-Royce claims that on its own it could fuel 250 .
Originally thewas due to make its first flights this year. The current health crisis and its constraints will certainly delay the process, but the firm remains confident and intends to achieve its speed record early next year. For Rolls-Royce, the development of ACCEL is only the beginning of an investment in the creation of engines for airliners freeing up by 2050.
Electric plane: Rolls-Royce ready to beat the world speed record

Rolls-Royce developed the airframe for the electric racing aircraft as part of its ACCEL project. With this device, he intends to exceed 480 km / h! First test in spring 2020.
When Futura presented the electric speed plane projectRolls-Royce, it was just a concept. Today, the manufacturer has developed the cell of the device. In aviation, it is said that a beautiful plane is a plane that flies well. The design of the ACCEL project is rather successful, even if it closely resembles that of a , the Sharp Nemesis NXT. It is finally quite logical since it is derived from this racer made up essentially of . Unlike the Nemesis NXT, which holds the speed record for an airplane in its class with a top speed of 657 km / h, the ACCEL will peak at over 480 km / h with its electric motor. If Rolls-Royce succeeds, it will be the fastest electric. For the moment, the record is 334 km / h. It is held by a , a modified aerobatic plane, whose engine was replaced by an engine .
Towards a record in 2020
It is in 2020 that the manufacturer plans to fly the aircraft which will be equipped with three electric motors designed by Yasa accumulating a power of at least 500 horsepower. It is a 750 kW battery comprising 6,000 cells that powers the engine. To achieve such a velocity, theheats up enormously and their cooling is one of the important points in the design of this aircraft.
Named ACCEL for Accelerating the Electrification of Flight, this racing aircraft allows Rolls-Royce to conduct experiments in order to create by 2030 afor a real commercial aircraft.
Rolls-Royce to create the world's fastest electric aircraft

Rolls-Royce and its partners are working on a single-seater electric aircraft. It is likely to break the world speed record held since 2017, by a device designed by Siemens.
If all goes as announced, in 2020 adevelopped by should break the world speed record for this type of device. Currently, he is held by the equipped with a Siemens engine which won it in 2017 with 337.5 km / h. At the head of a grouping of several technical partners, Rolls-Royce is aiming for 480 km / h and would ultimately like to tackle the record for the Schneider Cup of 1931, during which a Supermarine S.6B, with a Rolls-Royce "R" engine, had reached 552 km / h.
For its single-seater propeller-driven electric aircraft, the British manufacturer is developing a 750 kW battery with 6,000 cells. The groupis composed of three electric motors manufactured by YASA which deliver a total of 500 horsepower. One of the main technical challenges that designers face is in battery and motor cooling.
A journey from Paris to London with a single charge
For this, a series ofwill continuously monitor 20,000 points in the powertrain, including battery voltage, temperature and engine condition. The announced could allow a flight between Paris and London in one go.
Compared to a conventional airplane, the propeller blades rotate at a much lower rpm of 2,400 rpm to provide more stable and much quieter operation. See you in 2020 to find out if thiskept his promise! Remember that Rolls-Royce is also working on a electric.
