Abstract
Disclosed is a vertical take-off and landing aerodyne, including a fuselage, two wings, horizontal flight propulsion unit and at least one pair of rotors intended to provide propulsion and lift in the take-off and landing phases. The rotors are retractable and the horizontal flight propulsion unit includes a counter-rotating propeller, situated at the tail of the aerodyne, and a drive unit for rotating the counter-rotating propeller, the counter-rotating propeller being capable of being oriented by a control unit about two axes, one parallel to the yaw axis and the other parallel to the pitch axis of the aerodyne, such that the counter-rotating propeller is used for controlling the attitude of the aerodyne, the latter therefore not having a tail unit.
