Abstract: • A novel ECSP based on LiClO 4 /NaNO 3 oxidizer is characterized. • ECSP shows stable 280 V on/off switching and rapid extinction. • TG-DSC-FTIR-MS identifies the ECSP thermal decomposition paths. • β-Cyclodextrin reduces ECSP decomposition temperature without heat buildup. • The ECSP high-temperature desensitization mechanism is proposed. An electrically controlled solid propellant (ECSP) using lithium perchlorate/sodium nitrate as the oxidizer was prepared. The ECSP was verified to be capable of continuous and stable combustion under a 280 V voltage using the established electrically-controlled combustion test system, while it extinguished rapidly after power cutoff. The thermal decomposition properties of the ECSP and its raw materials were analyzed using TG-DSC-FTIR-MS coupled techniques. Comparative analysis of the combustion residues after flame burning and electrically controlled ignition was performed via separate FTIR tests. The results revealed that β-cyclodextrin significantly lowers the thermal decomposition temperature of the propellant system without leading to heat accumulation. Based on these findings, the formation mechanism of the high-temperature desensitization characteristics of this ECSP was further elucidated. [Display omitted] [ABSTRACT FROM AUTHOR]
