This study investigates the application performance of a hydrazine decomposition catalyst using a 200 N thruster device.On the basis that the physical and chemical properties of the catalyst meet the application requirements,the mechanical environment adaptability of the catalyst is investigated using a 200 N thruster device.The low-temperature cold start performance,low-temperature steady-state performance,normal temperature positive and negative bias steady-state performance,and pulse lifetime performance of the catalyst are also investigated.The results indicate that the catalyst has a hydrazine catalytic decomposition efficiency above 99％,excellent mechanical strength,good mechanical environment adaptability,and high hydrazine catalytic decomposition activity and stability.The test shows that the catalyst can meet the usage requirements of a 200 N thruster device.
