The objective of this course is to get anunderstanding of advanced space propulsion concepts for innovativeapplications. The following systems arecovered: for in-space propulsion,electric propulsion systems have a much higher specific impulse than chemicalsystems and require therefore lesspropellant to accomplish a mission. Solarsails use the freely available solar radiation for propulsion and requiretherefore no propellant at all. For into-space-propulsion, ramjets with sub-and supersonic combustion, which can be combined with conventional rockets, canoffer a significant higher performancethan the latter alone. The course setsthe basis for independent lecture of the relevant literature and autonomousscientific research.
