At the Paris Air Show, AgustaWestland shows off an exotic single-person aircraft designed to investigate all-electric, no-hydraulic flight systems.
An experimental unmanned flying cargo system, Baldwin Technology's Mono Tiltrotor, would integrate a coaxial rotor, a folding lifting wing system, and a lightweight airframe.
Some days, an aircraft wants to be more than just a troop transport. The Bell Boeing V-22 program is now trying out the tilt-rotor Osprey to see how it might fare as a flying gas station.
Don't expect an all-electric plane to carry hundreds of passengers soon, but in some corners of aviation, battery-powered aircraft are attracting industry interest.
The controversial tilt-rotor aircraft has defied its critics with its performance to date in its harsh new landscape.
