The invention relates to a rotor for convertible aircraft, which is actuated by propeller motors (5) by means of a torque transmission (23) which is equipped with rotor braking (21) and clutch (22) means. The invention also comprises means for controlling the pitching and warping of the rotating shaft (24) of the rotor. The aforementioned transmission comprises: a lower Cardan joint (25) which is used to transmit the torque from the propeller motors (5) to the rotor, and an upper Cardan joint (26) having a casing (27) that rotates on a circular bearing (28) which is solidly connected to the structure of the aircraft (1) and which is used to transmit the torque from the propeller motors to the rotor and to transmit the lift force from the rotor to the fuselage. According to the invention, at least one of the blades (7, 8) comprises: a first motor (17) which is solidly connected to the end of the rotating shaft of the rotor, such that the blade can be folded onto an axis (30) that is parallel to that of the rotor shaft; and a second motor (18), such that the collective or individual pitch of the blades of the rotor can be varied according to an axis of rotation (34) that is perpendicular to that of the shaft (24) of the rotor (6). |
