Енютина Т. А., Кулагина Л. В., Гафуров М. М. ИСПОЛЬЗОВАНИЕ ЭФФЕКТА РАНКА–ХИЛША В ПРАКТИКЕ ЛИКВИДАЦИИ ЧРЕЗВЫЧАЙНЫХ СИТУАЦИЙ (с. 50-54)
Аннотация. Предложен технический прием оказания помощи пострадавшим людям в случае возникновения чрезвычайной ситуации, а именно при обрушении конструкций, так как не всегда возможно провести срочную оперативную разборку обрушений и спасение людей в процессе выполнения аварийных и поисково-спасательных работ. В этих обстоятельствах в зависимости от температуры окружающей среды организм человека может подвергнуться переохлаждению или перегреву. В таких же условиях могут оказаться и сами находящиеся рядом спасатели, когда время извлечения пострадавшего по каким-то причинам затягивается. Одним из способов поддержания жизнедеятельности организма человека может служить подача нагретого или охлажденного потока воздуха, который можно получить от вихревой трубки Ранка–Хилша. Воздух сжимается компрессором либо переносным, либо от двигателя пожарной машины.
Ключевые слова: эффект Ранка–Хилша; вихревая трубка; ликвидация чрезвычайных ситуаций.

Abstract. A technical method of providing assistance to injured people in the event of an emergency, namely, in the event of a collapse of structures, is proposed, since it is not always possible to carry out urgent operational dismantling of collapses and rescue people in the process of performing emergency and search and rescue operations. In these circumstances, depending on the ambient temperature, the human body may be subjected to hypothermia or overheating. In the same conditions, the rescuers themselves may find themselves nearby, when the time for extracting the victim for some reason is delayed. One of the ways to maintain the vital activity of the human body can be the supply of a heated or cooled air flow, which can be obtained from the Rank–Hilsch vortex tube. The air is compressed by a compressor, either portable or powered by a fire truck engine.
Keywords: Ranque–Hilsch effect; Vortex tube; Emergency response.
