The Airbus CityAirbus is a multinational project by Airbus Helicopters to produce an electrically-powered VTOL aircraft demonstrator. Full-scale testing of the ducted propeller drivetrain was completed in October 2017. Type certification and commercial introduction are planned for 2023.[1]The iron bird systems test prototype was completed and powered on in December 2017 on a test bench in Taufkirchen, Germany, to test the propulsion system chain, flight controls and propeller dynamic loads, verifying the electric, mechanical and thermal dynamics before being installed on the flight demonstrator by mid-2018.[3] The first structural parts for the demonstrator were produced by Airbus Helicopters. The aircraft's first unmanned flight was scheduled for the end of 2018, but that date was not met. Manned flights are planned for 2019.[4] DesignThe multirotor is intended to carry four passengers, with a pilot initially and to become self-piloted when regulations allow. The overall system is being developed in Donauwörth, with the electrical propulsion system built in Ottobrunn/Munich. The use of four ducted fans contribute to safety and low acoustic footprint. The fully integrated drivetrain has eight propellers and eight {{cvt|100|kW}} Siemens SP200D direct-drive electric motors. The fixed pitch propellers are controlled by their RPM. The four electric batteries total {{cvt|110|kWh}} and can produce a combined output four times {{cvt|140|kW}}. The design should cruise at {{cvt|120|km/h|knots}} on fixed routes with 15 minutes endurance.[1] Specifications{{Aircraft specs|ref= Airbus[1] |prime units?=met |crew= 1 optional |capacity= 4 passengers |length m= |span m= |height m= |max takeoff weight kg= |fuel capacity=110 kWh |eng1 number=8 |eng1 name=electric |eng1 type= ducted fan |eng1 kw=100 |eng1 note=, 4 × {{cvt|140|kW}} |cruise speed kmh=120 |endurance=15 minutes }} See also{{Portal|Airbus}}
