Interior ballistics
This course will enable learners to gain an overview of interior ballistics, ie all the areas and knowledge required to understand the propulsion of a barrel-action projectile.
The course lasts 5 days (30 hours) and includes:
- 11 x 1.5-hours lectures
- Day visit to a state test center and ammunition factory (factory visit linked to manufacturer opportunities); day visit to a research center
- 1-hour panel discussion
The course is open to anyone interested in the propulsion of a barrel-action projectile at any stage and any caliber.
Lectures provide both a solid theoretical foundation and a useful overview of the specific problems an engineer encounters with design, expertise, simulation or testing.
This course will enable learners trainees to deepen their knowledge and cooperate more fruitfully with ballistics experts they encounter later; it will also enable them to understand the technical choices and compromises behind the sizing of a weapon system and the determining of its performance.
Course level: Basic/Advanced
Course accessible to ENSI-level learners.
