CATALYSTS INFLUENCE MECHANISM ON COMBUSTION OF LOW-CALORIE PROPELLANT

By use of electron microscope and X-ray analysis mechanism of nickel-lead phthalate and copper-lead phthalate action on combustion of low-calorie propellant was investigated. It was established that input of copper-lead phthalate in the propellant increases carbon-black formation on the combustion surface, while nickel-lead phthalate, in reverse, leads to carbon oxidation. There is a significant accumulation of catalyst particles on the carbon frame (up to ~68% mass) in case of considerable catalyst effect. There is a dependence of efficiency of additives action on carbon frame with catalysts cover degree of combustion surface. Leading zone on combustion of catalyzed propellants is the zone above the combustion surface - carbon frame with catalyst particles.
