[IN VIDEO] The Darpa works on an electric plane with vertical take-off Vertical take-off planes have been around for about a hundred years, but this new model presented by Darpa (the US Army’s research and development agency) is quite astonishing. In flight, its wings rotate and achieve high speed in a very short time. Here is a video demonstration of this new kind of aircraft.
After engine tests on the ground, then a first 15-minute flight on September 15 in the United Kingdom, the Astromobile Spirit landed on January 4, 2004, twenty days before its twin brother Opportunity, in the Gusev crater , suspected of having hosted an ancient lake in the past.
In Spirit of Innovation designed by Rolls-Royce now changes to Speed having direction and intensity is represented by a vector, the speed vector. Relative speed is the speed of one body in relation to another or in relation to a landmark. Speed higher by accumulating three world records. With its powerful electric motor of 400 kW developing the equivalent of 500 hp, the Spirit of Innovation took off on September 16 at 3:45 p.m. from Boscombe Down Air Base in Wiltshire (England). While the manufacturer’s goal was to exceed the speed of 480 km / h, the aircraft maintained itself at 555.9 km / h over a distance of 3 km. An absolute record for an electric aircraft. Better yet, Rolls-Royce would also have recorded a peak at 623 km / h.
The Spirit of Innovation is also the holder of a second speed record over distance, with 532.1 km / h over 15 km. Finally, the International Aeronautical Federation must also approve a final record, that of the fastest rate of climb for an electric aircraft. The device climbed to 3,000 meters in just 202 seconds.
In short, the Spirit of Innovation is currently the fastest electric vehicle in the world. To its list of achievements are also added technological prowess. Thus, with the 6,000 cells, its battery would form the highest density ever integrated in an aircraft. Much more than breaking records, the aircraft is above all a concentrate of technologies whose objective is to equip 100% electric airliners or flying taxis in the future. It could well be in the near future as Rolls-Royce and the aircraft manufacturer Tecnam are working with Widerøe , a Norwegian regional airline, to build an aircraft of electric transport which would be operational by 2026.
Rolls-Royce electric plane ready for take off

Here is the time for the last test on the ground of the Spirit of Innovation, the electric racing aircraft designed by Rolls-Royce. Fully assembled, the aircraft was able to successfully perform maneuvers on the ground to test the correct integration of its electric propulsion system into the airframe.
The development of the airframe of the aircraft has been validated, the engine has been tested, the various components assembled, now is the time to make the first turns of the wheels for the ACCEL electric aircraft ( Accelerating the Electrification of Flight ) from Rolls-Royce. It is not a question of making a flight, but what is called the taxiing of the plane on the taxiway, in other words, the runway. The Spirit of Innovation, that’s its stage name, was able to evolve on the ground powered by its electric motor of 500 hp, or 400 kW.
Despite appearances, even if the plane seems to have been content with simple turns of the wheels without taking the air , it is This is a critical test and the last test before a first flight. It makes it possible to check the correct integration of the aircraft’s propulsion system into the airframe and its behavior on the ground during taxiing. Controlling an airplane with such an engine power is quite difficult, especially on an aircraft equipped with a so-called conventional train, that is to say with a wheel at the rear of the The fuselage of a single-engine airplane contains the thruster in the front part, cockpit and cabin, separated or not, in fuselage and not at the front like on most modern airplanes.
“Taxiing”, a critical test
It is necessary to be able to precisely measure the power with a engine torque which tends to make the plane pivot on the left side during the rolling . The risk is that, with each change of direction, the centrifugal force which is applied on the center of gravity amplify the movement too much. A late or too weak correction can then lead to a destructive spin. This taxiing operation is also an opportunity to check its correct combination with the braking system.
The first flight is scheduled for this spring and, at full power, the aircraft will be able to evolve at more than 480 km / h, that is to say the speed record for an electric plane. As for the Formula 1 , this technological showcase will allow the introduction of certain innovations in the planes of tomorrow. This is particularly the case with the device’s high-density battery.
Aviation: Rolls-Royce tests its 500 horsepower electric motor
Article by Louis Neveu, published on 05/10/2020
Rolls-Royce has finished testing its revolutionary technology that will equip the world’s fastest all-electric aircraft. With its 500 horsepower engine and a revolutionary battery, the device could exceed 480 km / h.
After the development of the cell, here is the engine electric speed plane ACCEL ( 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.
The engine develops an unrivaled power of 500 horsepower. With him, the firm intends to beat the speed record in electric plane 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 is on this battery that most of the innovation is based. 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 supply energy 250 households.
Originally, the racer was 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 giving off zero carbon at the horizon 2050.
Electric plane: Rolls-Royce ready to beat the world speed record

Rolls-Royce has 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 the spring of 2020.
When Futura presented the electric speed plane project ACCEL Rolls-Royce, it was just a concept. Today, the manufacturer has perfected 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 quite successful, even if it closely resembles that of a racing plane , the Sharp Nemesis NXT. It is finally quite logical since it is derived from this racer made up essentially of carbon fiber . 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 racer . For the moment, the record is 334 km / h. It is held by a Extra 330 , a modified aerobatic plane, whose engine has been replaced by a Siemens .
Towards a record in 2020
It is in 2020 that the manufacturer intends to fly the device which will be equipped with three electric motors designed by Yasa cumulating a power of at least 500 horsepower. A 750 kW battery comprising 6,000 cells powers the engine. To achieve such a velocity, the battery heats 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 a hybrid engine for a real commercial airplane.
Rolls-Royce will create the fastest electric airplane in the world

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 a electric plane developed by Rolls-Royce should break the world speed record for this type of device. Currently, it is owned by the Extra 330 LE equipped with a Siemens engine which won it in 2017 with 337.5 km / h. At the head of a group 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 one Invented in 1910 by Henri Fabre
This is the French engineer and aviator Henri seaplane Supermarine S .6B, with a Rolls-Royce “R” engine, had reached 552 km / h.
For its single-seat electric propeller plane, the British manufacturer is developing a 750 kW battery with 6,000 cells. The thruster group consists of three electric motors manufactured by YASA which deliver a total of 500 horsepower. One of the main technical challenges designers face is battery and engine cooling.
