摘要

Rolls-Royce is preparing for the first flight of what it hopes will become the world's fastest electric-powered aircraft. The engine manufacturer is targeting a 300-mph+ speed record for its Accel (short for Accelerating the Electrification of Flight), an all-electric conversion of a Sharp Nemesis NXT racing aircraft that it plans to fly in the coming weeks, with an eye toward the first speed record attempts this summer. Rolls-Royce, together with partners Electroflight and UK-based electric-motor supplier Yasa, has transformed the Nemesis into a "battery with wings strapped on," Matheu Parr, Accel project manager for Rolls-Royce, said during a Royal Aeronautical Society webinar. "This aircraft has set out to be a pioneer for the third age of aviation," Parr said. "It will accelerate innovations and offer an understanding about batteries, electric motors, power electronics, cooling systems and thermal management." Six thousand lithium-ion cells designed for use in power tools drive the three Yasa-developed galvanically isolated 750-volt, 133-kW motors that give the aircraft a power output of 400 kW, which is the equivalent of nearly 550 hp.
