After the ZEHST concept plane hypersonic airliner, another EADS concept aimed at the more immediate future. It’s called VoltAir, and it’s a proposed all-electric airliner that could be flying within 25 years.
Two next-generation lithium-air batteries of VoltAir would power two highly efficient superconducting electric motors, which would in turn drive two co-axial, counter-rotating shrouded propellers at the rear of the aircraft.
The motors would have a relatively easy go of it, and also be very quiet.
The batteries would be housed in the lower front section and recharging would take place when the batteries were out of the aircraft.
