DOUBLE-BASED SOLID FUEL Russian patent published in 2017 - IPC C06D5/06 C06B25/18 

FIELD: chemistry.

SUBSTANCE: fuel contains nitrocellulose, nitroglycerin, stabiliser of chemical resistance - centralite, diphenylamine, or a mixture thereof, technical carbon, industrial oil, zinc stearate, oxide or iron hydroxide with a particle size of 0.1-1.0 mcm, copper oxide chemically precipitated on fibres of nitrocellulose, polyacrylamide. Fuel for a number of products (large-sized charges with fuel-channel radial combustion guns) may additionally contain a combustion stabiliser, which is recommended to use calcium carbonate in the form of a fine powder, for example, chalk chemically precipitated in an amount of 0.5-2.5% in excess of 100%. The fuel composition provides a burning rate of 22-30 mm/s at a pressure of 100 kgf/cm² with a low dependence of the burning rate on pressure (a power-law measure in the combustion law is not more than 0.6) of an environmental friendly one, namely, containing no toxic compounds of the first class of danger in accordance with GOST 12.1.007-76 of solid rocket fuel.

EFFECT: environmental friendliness.
