PYROTECHNIC COMPOSITION FOR ACTIVE EFFECT ON SUPERCOOLED CLOUDS AND FOGS Russian patent published in 2023 - IPC C06B29/22 A01G15/00 E01H13/00 

FIELD: explosives.

SUBSTANCE: invention relates to pyrotechnic compositions intended to provide active effect on supercooled clouds and fogs for the purpose of dispersing said clouds and fogs, preventing hail damage, and inducing precipitation from clouds using ice-forming nuclei resulting from the combustion of the pyrotechnic composition. Pyrotechnic composition for active effect on supercooled clouds and fogs includes an oxidising agent, fuel, ice-forming compounds, process additives and aerosolising compounds of high-boiling substances modifying the resulting aerosol spectrum. Organosilicon compounds — polyorganosiloxanes with a degree of polymerisation in the range of 4 to 400 are used as compounds modifying the aerosol spectrum in size.

EFFECT: higher efficiency of the used pyrotechnic agents, increase in the economic effect of hail prevention and precipitation increasing works.
