Learning outcomes
The module teaches the basics of space technology. Space systems engineers need general knowledge of various technical and programmatic topics in space technology. This knowledge allows them to classify their space projects in terms of scope, space history, space environment, possible orbits,
launch vehicle options, and many other aspects. The module introduces software tools relevant to space engineers. Students will be able to use these tools and apply the knowledge acquired in other modules and in their professional careers.
After successful completion of this course, students will be able to: - List and describe various space activities
- to name historical events and personalities in space history - to describe - to explain the properties of
different and special orbits - to reproduce coordinate and time systems - to describe and categorize Kepler elements - to calculate impulsive
orbital maneuvers and delta v requirements - to differentiate and classify spatial and planar orbital maneuvers - explain interplanetary
orbits - explain the basic principles of rocketry and the main elements of a rocket engine
- calculate basic parameters of a rocket (e.g.
masses, thrust, specific impulse, efficiencies and speeds) - the basic functional and structural design of launch
vehicles with fixed and liquid propellant - describe space transport systems and elements of launch vehicles - describe the procedures and logistics relevant to
the construction and operation of launch vehicles (e.g. integration, tests, launch complex, launch procedures, recovery) - differentiate between different types of propulsion and systems - Recognize and evaluate combustion
cycles - Explain the challenges of the space environment for a space mission - Differentiate and name satellite payloads as well as satellite buses and their subsystems - Summarize the
technology and benefits of space stations
- discuss the challenges of reentry - apply scientific tools
to carry out numerical simulations and calculate ascent trajectories and orbital maneuvers - use software tools to document scientific work in a professional environment
