On Monday at Heli-Expo, AgustaWestland revealed that it has been secretly flying an all-electric vertical takeoff and landing demonstration aircraft powered by twin-electric, direct-drive tiltrotors. The “Project Zero” tiltrotor was designed and built in six months by the company’s advanced concepts group and has been flying since 2011. It features elevons for pitch and roll control and in forward flight, a V-tail for longitudinal stability, and a lifting body design with two integrated tiltrotors that can be tilted through 90 degrees. The rotors are driven by advanced electric motors powered by rechargeable batteries.
