Rolls-Royce recently unveiled its new electric aircraft, which the company hopes will soon become the world’s fastest,media New Atlas reported. At Gloucestershire Airport, the company showcased single-passenger, zero-emission SCANTId ACCEL aircraft, which are expected to reach a top speed of 300mph (480km/h) early next year.
In the world of electric aircraft, development is similar to what we see in electric vehicles. In both cases, technology develops in two opposite directions. On the one hand, some engineers start with low-performance electric aircraft and then evolve, but on the other hand, some people are looking for high-performance aircraft, which they can reduce to something more practical.
Rolls-Royce says its electric aircraft will use a new electric propulsion system, which will be tested on the company’s IonBird tester before being installed on the final aircraft. The electric aircraft’s three high-power density axial 750R motors will run on the highest power density battery pack, which has 6,000 battery units that can produce up to 750 kW (1005 hp) of power and a single-charge range of 200 miles (320 km). It is also equipped with a direct cooling system that protects the battery at high speeds. The aircraft is not only zero-emissions, but also has lower RPM propeller blades to reduce noise. In addition, the power train has a power efficiency of 90% compared to the 50% efficiency of Formula One cars.
Rolls-Royce’s new electric aircraft is part of the company’s ACCELERATed flight electronics (ACCEL) program and is being established in partnership with motor and controller manufacturer YASA and aerospace start-up Electroflight, as part of the Aviation Technology Institute (ATI), Funded by the UK’s Department of Business Energy and Industrial Strategy (BEIS) and Innovation UK.
Rob Watson, head of Rolls-Royce’s electrical division, said: “Making the world’s fastest all-electric aircraft is nothing more than a revolution in the aviation industry, and we are delighted to launch the ACCEL project aircraft. This is not only an important step towards a world record, but will also help develop Rolls-Royce’s capabilities and ensure that we are at the forefront of developing technologies that can play a fundamental role in the transition to a low-carbon global economy. “
If all goes well, the plane will have a record 300 mph attempt in the spring of 2020.
