Abstract
Computational support of the development of mortar training systems is
discussed in this paper. The shell-in-shell system used in the simulator raised a
number of non-standard technical and computational problems starting from the
requirement to distribute the propelling blast energy between the warhead and
the ballistic barrel, finishing with the requirement that the length of the
warhead’s flight path must be scaled to combat shell firing tables. Computational
optimisation of the system parameters comprising external and internal ballistics
problems was an integral part of the project.
Keywords: simulator, mortar, internal ballistics, external ballistics, blast
energy.
1 Introduction
Development of military training equipment is an important factor minimising
costs and maximizing training effectiveness [1, 2, 3]. The goal of the project was
to develop mortar simulators with re-usable shells mimicking the combat
shooting process. Mortar simulators must be applicable in field training of early
career soldiers as well as in different combat training scenarios. Double-mass
shell system is exploited. It comprises ballistic barrel and warhead. The
relatively heavy ballistic barrel must be ejected from the barrel of the mortar
after the blast. Its flight distance must be only few meters, − so that the operators
could quickly collect the re-usable external shells. The flight distances of the
warhead must be 10 times shorter than of the combat shells (data from combat
firing tables). Moreover, only one propelling charge in the warhead is allowed –
the blast energy must be distributed between the ballistic barrel and the warhead
