Most mono-propellant thruster technologies were developed in the 1960s and the basic principles and fundamental structures, such as the catalyst and propellant, have remained in use without major technical innovation. Conversely, much remains to b...
The monopropellant hydrazine thruster is widely used in many satellites and explorers propulsion system and launch vehicle RCS due to its simplicity, high reliability, and robustness. The life of monopropellant hydrazine thruster is mainly determi...
