Embodiment Construction

[0039] Figure 1 to Figure 4 Shown is a first embodiment of the present invention, according to which the drone comprises an upper annular propeller 2, a lower annular propeller 4 (which together form two counter-rotating annular propellers), and an upper chamber 6 , the lower chamber 8, and the mechanical device for driving the propeller.

[0040] The two propellers are arranged symmetrically in a plane called the equatorial plane. In the following description, we assume that this plane is horizontal. Besides that, the two propellers are placed parallel to each other. That is, the separation distance between the two propellers is always fixed along their entire periphery.

[0041] The two propellers exhibit a similar structure. In a preferred embodiment of the invention, the structure of the propeller is very simple. In this preferred embodiment, an annular propeller comprises, on the one hand, a set of blades 10 and, on the other hand, an inner annular part 12 and an ou...

Abstract

The invention relates to a drone comprising: two contra-rotating annular propellers (2, 4) defining a plane therebetween which is referred to as an equatorial plane and is assumed to be horizontal, means for driving the propellers, a load arranged below the equatorial plane, and means (20) for moving the load relative to the equatorial plane, an enclosure referred to as an upper enclosure (6) filled with a gas or a gaseous mixture having a density of less than 1 and arranged essentially above the equatorial plane, and an enclosure referred to as a lower enclosure (8) filled with a gas or a gaseous mixture having a density of less than 1 and arranged essentially below the equatorial plane, the load being placed inside the lower enclosure (8).

Description

technical field [0001] The invention relates to a high-altitude unmanned aerial vehicle. [0002] The field of the present invention particularly relates to the field of high-altitude long-endurance unmanned aerial vehicles, referred to as HALE (Haute Altitude Longue Eudrance) unmanned aerial vehicles. Background technique [0003] A drone is an aircraft that does not need a pilot. Many drones are very similar to airplanes and drive in the same way as airplanes. [0004] UAVs are often used for military purposes and / or for observation missions. Therefore, when the UAV is dispatched over the observed area, in order to ensure that it can complete the task, the aircraft is usually equipped with shooting equipment and image transmission equipment. Among the known UAVs, there are those with a flight range exceeding 10,000 meters. For example, some UAVs have a flight range of 20,000 meters and can continue to fly in the air for more than 24 hours. In addition, their payload can...
