Abstract
This report summarizes the work done during 2015 within internal ballistics. The work has been partitioned in three areas: modelling of internal ballistics, projetile motion, and experiments. In internal ballistics a simple thermodynamic model has been implemented and compared to a gas dynamic model. The results from these have formed the base for an initial state for CFDmodelling. Within projectile movement a method for expanding meshes have been validated with respect to energy balance. Within experiments, design and function of a ballistic pendulum has been studied.
