FIELD: rocketry.
SUBSTANCE: composite solid propellant contains an oxidising agent - potassium or sodium perchlorate, organic fuel: sorbitol or polymerised epoxy resin, and a combustion catalyst metal salt containing a nitrile group: cyanide or permanganate, or thiocyanate. Catalyst additive accelerates fuel combustion, which reduces value of exponents in combustion law.
EFFECT: invention stabilises fuel combustion in range of low pressure 1-30 atm and solves main problem of fuel based on metal perchlorates - lower "minimum pressure of effective combustion".
