Abstract

Abstract: To explore the influence of organic fluorine-contained additives on aluminum agglomeration during combustion of the aluminized polyether propellants, a high-speed video camera is used to monitor the combustion process of propellants, and the scanning electron microscope (SEM) and energy dispersive spectrometer (EDS), laser particle size analyzer, X-ray diffractometer and real-time particle size analyzer are used to analyze the morphology, size, composition and real-time particle size of condensed combustion products of propellants. The results show that the organic fluorine-contained additives contribute to reduce the size of burning aluminum particles. The coarse agglomerate size is reduced obviously after adding 2% organic fluorine-contained additives. The average diameter of condensed combustion products is decreased from 5.83 μm to 3.06 μm at 7 MPa. XRD results show that α-Al₂O₃and θ-Al₂O₃ are nearly disappeared in condensed combustion products due to addition of organic fluorine-contained additives, in which δ-Al₂O₃ and γ-Al₂O₃ are generated.
