The ends of the consoles while moving down to the fuselage. The lock, made, for example, in the form of a rod passing through the holes in the rod 16 and in the frames 22, 23 (not shown in the drawing), fixes the position of the consoles 2, 3 in the folded position.

When the wing is in the flight position, the actuator moves the rod 16 in the reverse order, and the lock locks the wing console 2, 3 in the flight position.

A vehicle equipped with the wing folding mechanism described above, in the flight position of the consoles 2, 3 by means of an air propulsion device 21, made, for example, in the form of a propeller, flies. After landing, by means of the wing folding mechanism, the root ribs 10, 11 of the consoles 2, 3 of the wing stem 16 rise up, turning relative to the hinges 8, 9 of the struts 4, 5 with the fuselage 1. In this case, the ends of the consoles 2, 3 move down to the fuselage. Further, the vehicle, under the action of the traction force of the air propulsion device 21, for example a propeller, moves on the chassis 20 on the surface, and can independently reach a parking lot, for example, a garage located in a village near the landing site. Also, a vehicle with consoles 2, 3 in the folded position can be towed behind the car.
