Rolls-Royce electric plane breaks record, reaching 387.4 mph

Only two months after the first flight, the Rolls-Royce “Spirit of Innovation” reached a top speed of 387.4 mph, tentatively breaking the speed record for electric aircraft. Small invention There are reports. It also claims a top speed of 345.4 mph on a route of 3 kilometers (1.86 miles), the shortest time (202 seconds) at an altitude of 3,000 meters (9,843 feet). These records have not been certified, but if the speed of 345.5 mph remains the same, it will exceed the current record of 213 mph held by the Siemens-powered Extra 330LE at an impressive 132 mph.

Rolls Royce (aerospace, not a car company) conducted a test on November 16 as part of its ACCEL (Accelerated Flight Electrification) project. In order to obtain record certification, it submits the test to the Federation of International Aviation (FAI), the body responsible for world aviation records. If confirmed, the speed will be very impressive considering that the aircraft only flew for the first time in September-which shows that it can fly faster if it has more time.

The innovative spirit is an old-fashioned “tail-wing” aircraft (turned to the rear), with the roof pushed back, looking as fast as it. It is powered by a 400 kW (535 horsepower), 750 volt electric motor. Rolls-Royce said it uses “the highest power density propulsion battery pack ever assembled in the aerospace industry” with 6,480 batteries.

As Engadget detailed in the explainer, electric airplanes are not practical because the energy density of current batteries is 50 times lower than jet fuel. However, they do have some hope for very short trips, such as a 30-minute short trip between Vancouver and Victoria in Canada. Unlike non-turbocharged ICE engines, the electric motor maintains full power as the aircraft climbs, making it ideal for trying time-to-altitude records—as the spirit of innovation just demonstrated.
