Abstract—This paper reviews the design process of a bi-propellant space propulsion thruster to output 80N nominal thrust. The thrust chamber design problem of a space propulsion system is a complex and time consuming process. This is mainly due to performance constraints and high temperature flow requirements. These facts along with the specific geometry of the thrust chamber, make the fluid computations and structure analysis so difficult, particularly in terms of the thermal and force stresses. CFD and FEA are useful methods that helped to overcome these difficulties. Therefore, the thruster was successfully designed using ideal rocket equations and the design was successfully confirmed using CFD and FEA.
