FIELD: explosives. ^ SUBSTANCE: smoke-generating pyrotechnical facility for generation of distress signals consists of body, igniting unit, smoke-generating charge with igniting composition installed on it and grid, flash extinguisher and cover with outlet holes. Flash extinguisher is arranged in the form of volume scattering filter with through porous structure from metal threads. Metal threads are made of metal with heat capacity, which is sufficient for cooling of smoke-generating charge combustion products down to temperature that provides for stable smoke-generation. ^ EFFECT: stable action of smoke-generating pyrotechnical facility in gas-smoke mode, excluded penetration of flame force and high-temperature solid combustion products into atmosphere, and their ingress to surface of water basin with highly inflammable liquids. ^ 1 dwg |
