EADS all electric passenger plane design depends upon batteries achieving 1000 watt hours per kilogram and superconducting engines being developed. High temperature superconducting motors are expected to reach power densities of 7-8 kW/kg with almost no electrical losses. This compares to 7 kW/kg for today’s turboshaft engines. An essential requirement for the VoltAir concept is to have a light and low-drag airframe. Advanced carbon fibre composite materials are used, and an unconventional configuration with an optimum fuselage thickness-to-length ratio is selected to minimize aerodynamic drag while providing a maximum useful internal volume. The fuselage’s generous volume is used for a better integration of the landing gear, significantly improving the aerodynamic properties of the wing-to-fuselage junction.
EADS is a global leader in aerospace, defence and related services. In 2010, the Group – comprising Airbus, Astrium, Cassidian and Eurocopter – generated revenues of € 45.8 billion and employed a workforce of nearly 122,000.
