• Weapon Systems, Semester 1, position 1

The goal of course is that students learn the basic principles of combustion of materials and physics of explosion which are of importance for the realization of a function of weapon systems. Students should learn the contents of the process of explosion and burning of gunpowder and rocket propulsion materials as integrated chemical-technological systems. Ethical aspects of the use of explosive materials are considered.

Student gets knowledge for calculations of physics of explosion processes that influence warhead mechanisms and target efficiency. Student understand influencing parameters on the energy release by combustion processes. Student forms the scientific and experimental base for the development and creation of new knowledge in the field of energetic materials and energy release processes in defense technologies. Student perceives ethical aspects of the development and application of explosive materials.
