Making Catalyst and Preparing Catalyst Bed for Hydrazine Decomposition in Low-Thrust Monopropellant Thrusters
Monopropellant thruster of attitude control system is a requirement for the development and functionalization of satellites in space, which have expensive and high-tech technology. Hydrazine thrusters are currently the most widely used thrusters for guidance and control systems of re-entry and manned spacecraft. In this paper, making catalyst and preparing catalyst bed for hydrazine decomposition in low-thrust monopropellant thrusters are discussed. The combustion chamber contains catalyst granules. The catalyst volume is selected in an optimum level. Also, catalyst materials, construction techniques of the catalyst and catalyst bed, constructional considerations and requirements, and its configuration are introduced and discussed in detail.The present study is applicable. At present, the aerospace research institute is preparing the catalyst granules for use in 10 N hydrazine threshers of a space probe, and in the first stage it will be prepared at 50 cm3.
