Exactly two months later First flight, Rolls-Royce’s “Spirit of Innovation” hits top speed of 387.4 MPH, Temporarily smashing Speed record of electric aircraft, Gizmodo Reported. It claims a maximum speed of 345.4 MPH on a 3 km (1.86 m) course and a minimum time of 3,000 m (9,843 ft) altitude (202 seconds). Records have not yet been certified, but if the speed stands at 345.5 mph, it will beat the current record of 213 mph – a Siemens-powered extra 330LE – By an impressive 132 mph.
Rolls-Royce (aviation, not car company), conducted the tests on November 16. The record is verified, it is submitting to trial International Aeronautical Federation (FAI), the agency responsible for world aviation records. If confirmed, the speeds will be quite impressive considering that the plane made its first flight only in September – suggesting that with more time, it could go faster.
The Spirit of Innovation is an old-school “tail-dragger” aircraft (rear steering) whose canopy is pushed backwards and shows up as fast as it can. It is powered by a 400 kW (535 HP), 750 volt motor. Rolls-Royce says it uses “the most powerful-dense propulsion battery pack ever assembled into space” 6,480 cells.
A detail as Engadget Interpreter, Electric planes are not practical because current batteries have a power density of 50 times less than jet fuel. However, they do have some commitments, such as a very short trip 30 minutes Jant Between Vancouver and Victoria, Canada. And unlike non-turbocharged ICE engines, electric motors retain full power when boarding an aircraft, making them ideal for time-to-altitude record efforts – as the Spirit of Innovation has just shown.
