Abstract

Described is a four-rotor helicopter (1) comprising: a frame (2), four rotors (3) equipped with propellers (8) and designed for generating a lift, the rotors (3) being connected to the frame in such a way as to be grouped in two pairs (4), the rotors (3) of each pair (4) being positioned diametrically opposite a corresponding operating axis (X, Y), for allowing a rotation of the helicopter about the corresponding operating axis (X, Y), the operating axes (X, Y) not being parallel to each other. According to a first aspect of the invention, the helicopter comprises actuator means (9) associated with the propellers (8) of at least one of the pairs of rotors for varying, relatively, the pitch, the rotors of the at least one pair being connected by a kinematic mechanism to a same motor (5), for being rotated at the same angular speed. According to another aspect of the invention, the helicopter comprises a plurality of drive elements (10) connected to the rotors for tilting them relative to the frame, each rotor (3) being tiltable relative to the frame (2) so as to vary the orientation of the axis of rotation of the corresponding propeller.
