This course will introduce spacecraft propulsion technologies with primary emphasis on engineering and system level designs. Basic theories of rocket propulsion will be presented to enable an understanding of spacecraft system requirements and propulsion system selection processes. Propulsion systems currently in use or under development for various civil and military spacecrafts will be discussed. Specific topics include, orbital maneuver, thrust vector control, cold gas system, mono and bipropellant systems and solid propellant thrusters.
