Claim 1:
2. An aircraft, comprising:
at least one horizontal planar structure comprising a plurality of ducted propeller rotors with vertical axes, wherein each of the propeller rotors comprises a rotating ring rotatably mounted within a circular opening of the structure, the opening having an opening vertical axis through said at least one horizontal planar structure, said rotating ring defining an annular wall for ducting an air flow produced by each propeller rotor,
wherein the rotating ring further comprises a body and one or more blades which extend radially from the body towards a central axis of the propeller rotor and the one or more blades having tips terminating at a distance from the central axis of the propeller rotor, such that each propeller rotor is in a form of an annular propeller, wherein the rotating ring of each propeller rotor is controlled in rotation by an electric actuator comprising an axial flow annular electric motor, and
each axial flow annual electric motor including one stator element in a form of an annular disc carried by said structure of the aircraft, and axially interposed between two rotor elements in a form of annular discs, the two rotor elements connected to said rotating ring of the propeller rotor.
