[0001] The invention does not involve a verticel landing of the VILOL orion (the "Vertical Take - Off and Landing"), the ion is ensured, in particular at nicullage and the landing, pa at the corners an axial carrier blower, whose rotor .... elder around a rotational axis vertl The aerodyno according 1'inven'c ion is intended to evolve al according to its own: to be carried on the ground by a small boat or by a wide range of equipment, or for the use of such equipment or equipment for the purpose of the tanker. These areas are very simple, but they are not a simple, simple architecture, but they are devoid of any sense, and they are better realized than the airs. r.

On the other hand, at least one carrier blower is unsheathed, but preferably protected by a perforated protective structure.
[0002] Advantageously, the attitude blowers each comprise two coaxial and counter-rotating multi-blade propellers dragged each by a carrier. however, the protective effect of the circulating protector is known to the effect that the protector of the protector is known to the user. load damaged: to the Turkish carrier, do not support and def. e can be non-blowing so a congestion lia keeled.

Plump et al.) However, in the presence of a side wind, by imposing on the airflow a fixed direction substantially. the fairing (and emergency) blowers are streamlined to reduce the electrical consumption, and the center of gravity is placed under the carrier blower at or above the attitude blower fairings, offers a new compromise 30 and efficient for the air transfer of loads.
