Development of engineering solutions to protect energy facilities from UAV attacks.

With the constant increase of terrorist attacks on power engineering facilities, including those using UAVs, the article notes the urgency of developing technical solutions to protect these facilities. The article describes individual unsuccessful examples of protection against UAVs. The goal is development of constructive and technological solutions to protect energy facilities from UAV attacks. The emphasis is placed on the development of solutions with high technological reliability, expressed by the possibility of placing a protective structure in the confined nature of industrial sites. The existing regulatory literature has been studied, the importance of developing a set of rules for the design of protective structures is noted. Similar recently constructed protective structures have been analyzed, their advantages and disadvantages have been noted, and the experience of investigated structures that have already been attacked has been taken into account. Preliminary calculations and evaluation of the stress-strain state of structures were performed in the software package of the LIRA family. A range of technical solutions has been developed to protect objects from UAV attacks. The solutions are designed for objects of various configurations: rectangular, triangular and those close to a circle. The key engineering feature of the solutions is ensuring load-bearing capacity, spatial stability and rigidity without using support rods, making the developed solutions compact and capable of being placed in the confined nature of existing industrial sites. Applications for patents for inventions have been submitted for all the developed protective structures. Engineering solutions have been developed to protect objects from UAV attacks. The article suggests that subsequent studies may be aimed at further detailed elaboration of the developed solutions, including the design of the main conjugation joints, as well as conducting field tests of the developed protective structures to confirm their bearing capacity.
