Simulation of propellant combustion using the ICT-cellular-combustion-algorithm (ICCA)

The ICT-Cellular-Combustion-Mechanism (ICCA) is presented. Based on the theory of cellular automata it offers a fast and easy way to simulate the geometry changes during the combustion of solid gun propellants. It can provide a form function for even the most complex shaped propellants. The simulated form function can be used to simulate closed vessel pressure build up or as input for standard interior ballistic codes, e.g. ARL's IBHVG2. The theoretical foundations are outlined, the creation of input data is discussed and a two dimensional application example to investigate geometry variations due to variations in the production process for a real 19-hole gun propellant is given.
