Charge design for large-caliber artillery weapons must allow for many factors which can reduce efficiency and safety when these rounds are used in field situations. One of those factors is the temperature sensitivity of the propellant -- the change in performance caused by differing initial charge temperatures in otherwise identical artillery rounds. By comparing computer simulations of interior ballistic calculations, three factors in propellant grain design are explored -- geometry, deterrent layers and ignition delay. The IBHVG2 code is used to show the effects of each factor in a typical 1200-mm gun system. Temperature-related trends are computed, and the results are compared in tables and graphs.
