METHOD OF PRODUCING MIXED SOLID FUEL Russian patent published in 2011 - IPC C10L9/10 B82B3/00 

FIELD: chemistry.

SUBSTANCE: method involves preparation of a fuel mixture via successive mechanical mixing of oxidising agent with fuel-binder. The oxidising agent used is either ammonium perchlorate (APC) or ammonium nitrate (AN) or octogen (HMX) or a mixture of APC/AN, APC/HMX, AN/HMX, components being in ratio 1/1 for each mixture. The fuel-binder used is inert rubber (SKDM-80) or active rubber - polyurethane which is plasticised with nitroglycerine. The mixture additionally contains tin chloride powder with particle size (100-150) mcm, which is premixed for not less than 30 minutes with ultrafine aluminium powder with particle size less than 0.1 mcm, with the following ratio of components in wt %: ultrafine aluminium powder 87.5, tin chloride powder - 12.5. A hardener is added to the obtained mixture and the fuel composition is stirred for not less than 30 minutes.

EFFECT: rate of combustion of the mixed solid fuel increases depending on compositions of the oxidising agent and fuel-binder used in the fuel.
