The invention relates to the use of nanocatalysts with a high catalytic activity for the thermal decomposition of ammonium perchlorate (AP). To obtain these materials, magnetite nanoparticles (Fe3O4 NPs) were functionalized with two different groups of amine derivatives, tertiary amine (Fe3O4 NPs-A1) and quaternary amine (Fe3O4 NPs-A2). These nanocatalysts allow a lower activation energy to be obtained, accelerating the thermal decomposition of ammonium perchlorate.

The application discloses a method for catalyzing thermal decomposition of ammonium perchlorate by using a metal carbodiimide compound, and belongs to the field of solid rocket propellants. The method is characterized in that the metal carbodiimide compound is mixed into the ammonium perchlorate at a certain proportion and used as a catalyst to perform a thermal decomposition reaction of the ammonium perchlorate, so as to reduce the thermal decomposition temperature of the ammonium perchlorate and improve the heat release. Therefore, the method can be applied to the field of solid rocket propellants.

This invention belongs to the field of thrusters, specifically relating to an electrically controlled solid propellant afterburning propellant and a thruster system. The electrically controlled solid propellant afterburning propellant, by weight, comprises 65-95 parts oxidizer, 5-25 parts binder, and 0.3-5 parts curing agent. When the main combustion chamber is energized, the high-temperature, fuel-rich gas flow generated in the main combustion chamber washes over the surface of the afterburning propellant, rapidly reaching its pyrolysis temperature and instantaneously releasing oxygen. When applied to an electrically stimulated thruster combustion enhancement device, the afterburning propellant, upon heating, decomposes to produce oxygen-rich gas, which can mix and burn with the high-temperature, fuel-rich gas generated from incomplete combustion in the main combustion chamber. This fully utilizes the electrically controlled solid propellant, and the afterburning propellant offers controllable combustion, thereby significantly improving propellant combustion efficiency and thrust performance without affecting the thruster's electrically controlled combustion characteristics.
