| 摘要 |
There is described a convertiplane comprising a pair of semi-wings, a first and a second rotor which may rotate about relative first axes and tilt about relative second axes together with first axes with respect to semi-wings between a helicopter mode and an aeroplane mode; first axes are, in use, transversal to a longitudinal direction of convertiplane in helicopter mode, and are, in use, substantially parallel to longitudinal direction in aeroplane mode; first and second rotors may tilt about relative second axes independently of each other. |

1. A convertiplane (1) comprising:
a pair of semi-wings (3); a first and a second rotor (4) which may rotate about relative first axes (B) and tilt about relative second axes (C) together with said first axes (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; said first and second rotor (4) being tiltable about relative second axes (C) independently of each other; said convertiplane (1) further comprising: a first actuator (52) operatively connected to said first rotor (4) and adapted to tilt said first rotor (4) about a relative second axis (C); a second actuator (52) operatively connected to said second rotor (4) and adapted to tilt said second rotor (4) about a relative second axis (C); and a flight control system (49) adapted to control first and second actuators (52) independently of each other; each said first and second actuator (50, 52) comprising: a control unit (51) controlled, in turn, by said flight control system (49) on the basis of a plurality of flight and mission parameters; a fixed part (53); a piston (54) slidable relative to said fixed part (53) and controlled, in use, by said control unit (51); and a rod (55) which may rotate about a relative said second axis (C), is hinged to said piston (54), and is connected to said relative first and second rotor (4), so as to cause the tilting of said first and second rotor (4) about relative second axis (C). |
