Learning outcomes of the course unit
Learning basic principles of space flight mechanics. Acquiring knowledge of aerospace techniques (launchers, space vehicles and stations).
Prerequisites
The basics of mathematics – differential and integral calculus, common differential equations. The basics of common mechanics – force effect on a body, kinematics, dynamics.
Planned learning activities and teaching methods
The course is taught through lectures explaining the basic principles and theory of the discipline.
Assesment methods and criteria linked to learning outcomes
A graded credit of a compulsory subject is awarded for participation and elaboration of all tasks in exercises and a successful final test. Classification according to the Study and Examination Regulations of the FME.
Aims
The goal is to familiarize students with the branch of the area of aeronautical and cosmic means of transport that develops in a progressive way and with main problems of space flights.
Specification of controlled education, way of implementation and compensation for absences
Lectures are optional, exercises are mandatory. Replacement in the form of individually assigned and recommended literature for self-study.
