Exploration of space is never out of the news for long and the desire to construct lower-cost, reliable and more capable spacecraft has never been greater. At TU Delft years of technology development and research experience in space engineering allow us to offer this course, which examines spacecraft technologies for satellites and launch vehicles.
This course provides:
knowledge of the technical principles of rockets and satellite bus subsystems the ability to select state-of-the-art, available components analysis of the physical and technical limitations of subsystem components identification of the key performance parameters of different spacecraft subsystems comparison of the values obtained by ideal theory and real-life ones opportunity to make preliminary designs for a spacecraft based on its key requirements

Statica is de leer van mechanisch evenwicht.
Een lichaam beweegt niet (of is in een éénparige rechtlijnige beweging) als de som van de krachten die op dat lichaam werken nul is. Als ook de som van de momenten die op dat lichaam werken nul is, dan roteert het lichaam ook niet. De consequentie van deze twee evenwichtsvoorwaarden (som van krachten =0 en som van momenten =0), is dat voor een lichaam waarop een aantal bekende krachten werken de (onbekende) reactiekrachten bepaald kunnen worden . Dit is van groot belang omdat de grootte van de reactiekrachten de dimensionering en materiaalkeuze van toe te passen componenten bepalen. Binnen het vak “Statica” wordt in detail ingegaan op de verschillende mechanische belastingen, vaak voorkomende constructies en hoe te rekenen met de diverse belastingen.
