Abstract: There is disclosed a rotor (3, 3', 3", 3"') for an aircraft (1) capable of hovering, comprising a stationary support structure (10); a rotative element (11), which is rotatable about an axis (A) with respect to stationary support structure (10); at least one blade (13), which is operatively connected with rotative element (11); a source (30) of a magnetic field, which is either stationary or driven in rotation at a first rotational speed (ω1); and an electric conductive element (32), which is operatively connected to rotative element (11) and can be driven in rotation at a second rotational speed (ω2) different from first rotational speed (ω1); electric conductive element (32) is electromagnetically coupled with source (30), so that an electromotive force is magnetically induced in electric conductive element (32) itself, wherein two rings extend radially inward from a tubular body (51) of the rotor hub (12), the first ring (52) connecting to a plurality of thermally conductive rings (90) of a flow deflector (85) at an axial end of the rotor (3, 3', 3", 3"'), the second ring (53) supporting the electric conductive element (32).

Abstract: There is disclosed a rotor (3, 3', 3'') for an aircraft (1) capable of hovering, comprising: a stationary support structure (10); a rotative element (11), which is rotatable about a first axis (A) with respect to said stationary support structure (10) with a first rotational speed (ω2); at least one blade (13), which is operatively connected with said rotative element (11); and a transmission group (37, 37''), which comprises an output element (36, 36', 36'') rotatable about first axis (A) with a second rotational speed (ω1) different from first rotational speed (ω2).
