Abstract
1. Способ тушения крупномасштабных пожаров, включающий орошение очагов загорания инертной жидкостью, например, водой, доставляемой к очагам пожара различными транспортными средствами, включая летательные аппараты, отличающийся тем, что воду для тушения пожара получают из атмосферного воздуха, расположенного над зоной пожара, путем охлаждения этого воздуха до температуры ниже температуры точки росы. ! 2. Способ по п.1, отличающийся тем, что охлаждение воздуха производят с помощью равномерного распределения в объеме воздуха над зоной пожара испаряемого сжиженного азота из емкостей, находящихся в летательных аппаратах, например, вертолетах послойно на различных высотах в диапазоне высот от примерно 1500 до нескольких сотен метров от поверхности грунта, одновременно производят охлаждение воздуха в приземном слое воздуха зоны пожара из емкостей со сжиженным азотом, размещенных на поверхности грунта по периметру фронта пожара. ! 3. Способ по п.1, отличающийся тем, что массу сжиженного азота, необходимого для тушения пожара того или иного масштаба рассчитывают по термодинамическим соотношениям для охлаждения необходимого объема воздуха при известной его температуре до температуры точки росы над зоной пожара. 1. A method of extinguishing large-scale fires, including irrigation of the hot spots with an inert liquid, for example, water delivered to the hot spots by various vehicles, including aircraft, characterized in that the water for extinguishing the fire is obtained from atmospheric air located above the fire zone by cooling this air to a temperature below the dew point temperature. ! 2. The method according to claim 1, characterized in that the air is cooled by uniformly distributing in the air volume over the fire zone the evaporated liquefied nitrogen from tanks located in aircraft, for example, layer-by-layer helicopters at various heights in the altitude range from about 1500 to several hundred meters from the ground surface, air is simultaneously cooled in the surface layer of air of the fire zone from tanks with liquefied nitrogen placed on the ground surface along the perimeter of the fire front. ! 3. The method according to claim 1, characterized in that the mass of liquefied nitrogen necessary to extinguish a fire of one scale or another is calculated by thermodynamic ratios to cool the required volume of air at its known temperature to the dew point temperature above the fire zone.
