1. A convertiplane (1) comprising:

  • a pair of semi-wings (3);

    at least one first rotor (4) comprising a shaft (6) which may rotate about relative first axis (B) and tilt about a second axis (C) together with said first axis (B) with respect to said semi-wings (3) between a helicopter mode and an aeroplane mode;

    said first axis (B) being, in use, transversal to a longitudinal direction (A) of said convertiplane (1) in said helicopter mode and being, in use, substantially parallel to said longitudinal direction (A) in said aeroplane mode;

    characterized by comprising;

    an electrical power storage device (70;

    81, 82);

    andat least one electrical machine (71);

    said electrical machine (71) comprising, in turn,;

    a stator (72) which is electrically connected to said storage device (70;

    81, 82); and

    a second rotor (73) which is operatively connected to a shaft (6) of said first rotor (4);

    said electrical machine (71) being operable as;

    an electric motor for driving in rotation said first rotor (4) by using the electrical power stored in said storage device (70;

    81, 82);

    oras an electrical power generator for re-charging said storage device (70;

    81, 82) by causing the rotation of said first rotor (4) under the action of a wind current;

    said first rotor (4) being tiltable about said second axis (C) in a direction facing the wind current, when said convertiplane (1) is on ground and said storage device (70;

    81, 82) needs to be re-charged.
