Abstract

A convertiplane (1) is described that has a fuselage (2) with a first axis (A), a pair of half-wings (3), and a pair of rotors (5) arranged on mutually opposite ends of the half-wings (3). The rotor (5) comprises a mast (6) hinged on a second axis (B) and a plurality of blades (8) hinged on the mast (6). The mast (6) of the rotor (5) can be tilted with the second axis (B) about a third axis (C) transversal to the second axis (B) and with respect to the fuselage (2) to transform the convertiplane (1) between a helicopter mode and an aeroplane mode; the second axis (B) is transversal to the first axis (A) in the helicopter mode and is parallel to the first axis (A) in the aeroplane mode. The rotor disc (10) can be tilted about a fourth axis (G). The rotor (5) comprises control means (30) for controlling the cyclic pitch and collective pitch of the blades (8) comprising: a first actuator (21) controllable to vary the collective pitch, a second actuator (51, 20) controllable to vary the tilt of the rotor disc (10) about the fourth axis (G) and a rod (22) movable to alter the tilt of the corresponding rotor disc (10) about a fifth axis (H) according to the mode of the convertiplane (1).
