Description

The invention relates to radio engineering and EHF and microwave technology and can be used to form structures with chiral properties in space, in particular a low-reflective screening structure.

Known methods [1-7] of application and control for a swarm of unmanned aerial vehicles (UAVs), providing a given relative position of the UAV in the swarm, a given position of the UAV in space, a given position of the swarm in space. These methods are not used to form a chiral structure.

Known methods [8-10] for the manufacture of a chiral structure, which consists in the fact that the chiral structure is formed on a substrate. A common disadvantage of these methods are the restrictions on the choice of the shape, size and orientation of the chiral element imposed by the manufacturing technology of the structure.

The method [11], which is the closest technical solution to the claimed one, is free from this drawback. This method consists in the fact that a set of chiral elements of a given shape with predetermined characteristics is preliminarily made, and then these chiral elements are placed in space according to a predetermined pattern and fixed with a given orientation on a rigid dielectric structure.

The disadvantages of this method include the complexity of the operational changes in the properties of the chiral structure. The operations of removing, inserting or replacing a chiral element, changing the relative position, and orienting the chiral elements in the structure require considerable time and money, and in some cases are simply not feasible. This limits the scope of this method.

The essence of the invention is the expansion of the scope.

This essence is achieved by the fact that according to the method of forming a chiral structure, chiral elements with a given shape and size are placed in space according to a given pattern with a given orientation in space, while a swarm of unmanned aerial vehicles (UAVs) is formed, on each of which a chiral element is fixed, control swarm UAVs from the central station, while the carrier frequency of the control radio signals is selected outside the working range of the chiral structure, a swarm is placed under control from the central station PLA in a space with given coordinates, wherein the UAV is placed in the space in a predetermined pattern and orient them in the space so as to provide a predetermined position in space of the chiral element.

The drawing shows a structural diagram of a device for implementing the proposed method.

The device includes a swarm of UAVs 1, which includes UAVs with a chiral element 2, a central station 3, radio communication channels 4. UAVs with a chiral element 2 through radio channels 4 are connected to each other and to the central station 3.

The device operates as follows. Under control from the central station 3 through the radio communication channels 4, a swarm of UAVs 1 moves into space with the given coordinates. Under control from the central station 3, through the radio communication channels 4, UAVs with a chiral element 2 are placed in space according to a predetermined pattern, assuming a predetermined position, which ensures a predetermined arrangement of chiral elements in space and the formation of a chiral structure with desired properties.

In contrast to the known method, which is the prototype, in the claimed method, each chiral element carries a UAV. A chiral element can be mounted on a UAV, mounted in its body, or the UAV case itself can be a chiral element. Accordingly, the introduction of an additional chiral element, the removal or replacement of the chiral element in the claimed method is carried out simply by adding, removing or replacing the corresponding UAV in the swarm. Changing the relative position and orientation of the chiral elements is carried out by changing the relative position and orientation of the UAV in the swarm under control from the central station. The same applies to movements of the chiral structure in space. Thus, in contrast to the known method, which is the prototype, the inventive method allows you to quickly manage the properties of the chiral structure, which significantly expands the scope of its application.
