高铝固体推进剂中氟化物促进铝燃烧研究进展

The combustion agglomeration process of aluminum particles in solid propellants and its relationship with the ignition of aluminum particles were introduced. The theoretical models of combustion agglomeration of aluminum particles in solid propellants and corresponding methods for above problem were briefly summarized. The research progress of different fluorides, such as organic fluorides, metal fluorides and other types of fluorides, to improve the combustion agglomeration of aluminum powders in solid propellants at home and abroad were reviewed emphatically, and the mechanisms of inhibiting combustion agglomeration of aluminum powders by various fluorides and the combination of fluorides and aluminum powder were discussed. Some suggestions were put forward for further in-depth study on the promotion of aluminum combustion in solid propellants by fluorides: systematically study the influence of fluoride's physicochemical properties on the ignition of aluminum powder and its relationship with the particle size of the condensed phase products of aluminum particle combustion, and develop and apply liquid fluorine-containing oxidants, explore the mechanisms of fluorides inhibiting the combustion agglomeration of aluminum in solid propellants under higher combustion pressure, establish a general model and framework for the reaction mechanism of fluoride to inhibit the combustion agglomeration process of aluminum particles, and master the technology to suppress aluminum combustion agglomeration in high-aluminum content solid propellants.
