FIELD: chemistry.SUBSTANCE: invention relates to gas-generating compositions, which contain inorganic salts of oxygen-containing halogen acids, namely to pyrotechnic low-temperature rapidly burning gas-generating compositions for gas-generators, which are used in devices, applying mechanic energy of generated gases, for instance, in devices of rotor spin-up in turbo-jet engines, systems of rocket and torpedo control, shock-absorbers, jack-cushions, etc. Pyrotechnic low-temperature rapidly burning gas-generating composition includes in wt %: 58.0-68.0 nitroguanidine, 15.0-25.0 ammonium perchlorate, 5.0-11.0 urotropine, 1.0-7.0 ammonium bichromate, 2.5-3.5 butadiene-nitrile rubber and 1.5-2.5 phenolformaldehyde resin.EFFECT: gas-generating composition is characterised by high gas- productivity, low burning temperature, high burning speed, high durability of pressed charges in tension, low molar weight of gases and small content of condensed phase in products of burning.2 tbl, 5 ex |
