Effect of micro- and nano-CuO on the thermal decomposition kinetics of high-performance aluminized composite solid propellants containing complex metal hydrides

FirePhysChem, Год журнала: 2022, Номер 2(1), С. 36 - 49

Опубликована: Март 1, 2022

In the present work, an attempt has been made to unveil effect of micro- and nano-particles copper oxide (µCuO nCuO) on thermal decomposition composite solid propellants (CSPs) based ammonium perchlorate, hydroxyl terminated polybutadiene binary fuel mixture aluminum lithium tetrahydridoaluminate (AP/HTPB/Al+LiAlH4). The prepared CSPs were analyzed by different analytical techniques. second part study was devoted kinetic modeling process fabricated samples. light obtained results, it concluded that use µCuO nCuO accelerated CSPs. Moreover, incorporation LiAlH4-based propellant increased substantially heat release decreased average activation energy compared baseline reaction mechanisms investigated samples have clearly changed through nano- micro-CuO.

Experimental study of Al agglomeration on solid propellant burning surface and condensed combustion products

Defence Technology, Год журнала: 2022, Номер 26, С. 111 - 122

Aluminum (Al) particles are commonly added to energetic materials including propellants, explosives and pyrotechnics increase the overall energy density of composite, but aluminum agglomeration on combustion surface may lower efficiency resulting in a loss two-phase flow. Therefore, it is necessary understand mechanism surface. In this paper, high-pressure sealed chamber constructed, high-speed camera used capture whole process accumulation, aggregation surface, secondary near The microscopic morphology chemical composition condensed products (CCPs) then studied by using scanning electron microscopy coupled with dispersive (SEM-EDS) method. Results show that there three main types products: small smoke oxide oxidized vapor, usually less than 1 μm; typical agglomerates formed agglomerates; carbonized widely distributed, irregular movements agglomerates. particle size measured laser meter. As pressure increases from 0.5 MPa 1.0 nitrogen, mass average decreases 49.7%. ambient gas changed nitrogen air, 67.3%. as increases, higher oxygen content can improve reduce particles.
