Development of mortar simulator with shell-in-shell system – problem of external ballistics

Abstract

The shell-in-shell system used in the mortar simu-lator raises a number of non-standard technical and compu-tational problems starting from the requirement to distrib-ute the propelling blast energy between the warhead and the ballistic barrel, finishing with the requirement that the length of warhead’s flight path must be scaled to combat shell firing tables. The design problem of the simulator is split into two parts – the problem of external ballistics where the initial velocities of the warhead must be deter-mined and the problem of internal ballistics – where the design of the cartridge and the ballistic barrel must be per-formed.
