This paper presents a novel solution on the problem of trajectory mach and range reduction for a new training ammunition. The training ammunition is required by the armoured fighting vehicle user society to enable cost effective training simulating the use of APFSDS-T ammunition. The use of APFSDS-T ammunition is connected to very stringent safety considerations, as the penetrator easily exceeds existing safety templates for a typical practice ground. A novel projectile geometry has been studied with projectiles ranging from 12,7mm to 30mm. Analytical simulations have been carried out with a 6-DOF model to study stability and trajectory match. The results from analytical and numerical modelling with CFD-simulation, have then formed the base for test firing of projectiles, both as full- and subcaliber designs. The test results have then been studied to validate and update the analytical and numerical models. The effectiveness of utilizing concurrent engineering for the design and qualification of modern ammunition is also presented. The number of tests originally foreseen have been drastically reduced by means of introducing higher requirements for data gathering when testing. The work conducted have drastically improved the understanding of the complexity of exterior ballistics with requirements on trajectory match and range reduction.
