PROPULSION DEVICE FOR AERODYNE WITH ROTATING BLADE AND VERTICAL TAKEOFF AND LANDING, AND AERODYNE INCLUDING AT LEAST ONE SUCH PROPULSION DEVICE

摘要

Propulsion device (1) for rotary wing aerodyne and vertical takeoff and landing, comprising a hollow frame (4) and counter-rotating coaxial rotors (2, 3) with fixed-pitch blades (22, 32). The rotational drive means of each rotor (2, 3) comprise motor means and, for each rotor (2, 3), a rotating part capable of rotating around the yaw axis (A1), located in the 'central opening of the respective rotor (2, 3) and connected to the latter by a ball joint with finger, whose center is the intersection of the respective rotor disc and the yaw axis (A1) and whose prohibited rotation is that around the axis of rotation of the rotor (2, 3). Means (6) control the inclination of the rotors (2, 3) around the roll (A2) and pitch (A3) axes. Aerodyne equipped with the propulsion device (1). Figure to be published with the abstract: Figure 1.
