Mono-tilt rotor

Flight Global reports on this concept of a mono-tilt-rotor, being developed by AeroCopter. It is supposed to work using an outer ring (not shown) to drive the rotors, that also turn on the inner ring. Rotor propulsion is by “magnets”. It’s aimed at being a fast VTOL aircraft. Interesting if they ever get it to fly.
Excerpt: “AeroCopter has designed a 1,320kg (2,900lb) two-seat personal air vehicle with a cruise speed of at least 220kt (405km/h) and a range of 555km (300nm). There is also an unmanned air vehicle version.”
