Рассмотрены вопросы, касающиеся применения беспилотных авиационных систем (БАС) при тушении пожаров в зданиях повышенной этажности в условиях плотной городской застройки. В частности, статья посвящена оценке целесообразности применения возможных способов пожаротушения, характеризующихся различными системами подачи огнетушащего состава в очаг пожара при использовании пожарных БАС. Актуальность темы объясняется потребностью в выявлении обоснованных направлений, по которым следует вести разработки авиационных систем тушения пожаров, так как некоторые традиционные системы пожаротушения с увеличением высоты зданий становятся неэффективными. Особое место в качестве летательных аппаратов - носителей установок пожаротушения специалистами отводится беспилотным воздушным судам, при использовании которых может быть достигнуто наибыстрейшее реагирование на возгорание, в худшем случае этим снизив или не допустив его распространение до прибытия основных пожарных сил.

The article discusses issues related to the use of unmanned aircraft systems (UAS) at fire extinguishing in high-rise buildings in restrained urban conditions. In particular, the article is devoted to the assessment of application feasibility of possible fire extinguishing methods characterized by various systems of extinguishing agent discharge to the fire source when using fire UAS. The relevance of the topic is explained by the need to identify reasonable directions for development of aircraft fire extinguishing systems, since some traditional fire extinguishing systems become ineffective with an increase in the height of buildings. The use of unmanned aerial vehicles as carriers of fire extinguishing installations can provide the fastest response to combustion, which will reduce or prevent its spread before the arrival of the main fire forces. The authors consider that the method of aircraft fire extinguishing with the use of UAS is determined by the following: 1) utilized extinguishing agent, implemented by its impact on the fire source and possible mechanism of its delivery to the fire source. At the same time, the method of supply of extinguishing agent to the fire source shows the main types of fire extinguishing methods, which should include fire extinguishing using fire extinguishing agent: a) in liquid form when they are supplied from ground sources via hose lines through the on-board carriage barrel; b) from on-board tanks using jet systems; c) in special throw-in modules; 2) utilized technical fire extinguishing devices and UAS, through which the fire source is affected, as well as fire extinguishing technologies. The authors consider that the justification of the tactical and technical requirements for the listed elements should be made taking into account the provision of an acceptable ratio between their costs and the results of fire extinguishing. These issues should be the subject of further research.
