Abstract
Introduction. The purpose of the study is to formulate and analyze problems that should be solved before implementing the ideas of fire fighting in high-rise buildings by using unmanned aircraft systems (UAS). To achieve this purpose, the following concepts were considered and assessed: the possibilities of water and water-based fireextinguishing solutions delivery to the fire source from a ground pumping station using a hose line; delivering compression foam along a vertically positioned hose line; and, the possibilities of UAS for fire extinguishing; supply of fire extinguishing powders and aerosols placed on the UAS to the center of fire. Methods. The adopted in Russia hydraulic calculation methods, the results of the experimental studies on the compression foam, the existing theoretical and practical advances in the field of fire-extinguishing by jet delivering fire-extinguishing substances. Conclusions. The results achieved show that one of the ways to increase fire extinguishing capability in high-rise buildings can be provided by applying UAS for continuous horizontal supply of water based solution or compression foam to the center of fire, as well as supply of fire extinguishing powders and aerosols using powder fire barrels and pyrotechnic cartridges. However, to implement each of these methods, certain problems need to be solved. They are: the fire extinguishing height limitations a large capacity of UAS needed; a hydraulic calculation methodology for compression foam supply systems; safe use of UAS under the conditions of compression foam separation; the possibilities for developing supply equipment, which can be utilized by the UAS.
