“…Characteristics of the damaging action of ammunition [32] are the initial data for assessing the effectiveness of their use. Thus, during the EDH of their hulls, biomechanical lesions (wounds and contusions) and psychological effects on manpower in armor protection (MPAP) are created on fragments of various fractions.…”

The problem of determining the components of the structural-automatic model is solved by creating a graph of states and transitions. The purpose of the process is to form a formalized expression of the object of study in the form of a structural-machine model of the process of firing a mobile armored vehicle with a series of three shots with fragmentation-beam projectiles of directional action. This model can be further practically implemented during the development of the latest samples of fire resistance in order to reduce errors at the stage of system design. This approach reduces the cost of design and production of prototypes by up to 25 %. This paper considers the process involving interrelated elements of the components of a system while accounting for all possible variants of its behavior from the moment of detection to the failure of a single target in armor protection to perform tasks as intended. The execution of a fire task is considered as a set of certain procedures characterized by the average value of their duration. The explosive destruction of the hull of each fragmentation-beam projectile is characterized by the self-propagation of the reaction of explosive transformations based on tabular data on an armored combat vehicle. Appropriate procedures (phases) of firing a single target in armor protection are advisable to formalize to create preconditions for obtaining the value of a statistical indicator of the effectiveness of causing damage to the target and to study further alternative options for this process. For the proposed structural-automatic model of the process of firing a single target in armor protection with a series of fragmentation-beam projectiles of directional action, validation and verification were carried out, which demonstrated the convergence of the results that exceeded 60 %. The use of the structural-automatic model's components proposed in this work increases the probability of performing a fire task for the first shot from 0.23 to 0.88, for the second – from 0.35 to 0.95, for the third – from 0.45 to 0.98

Six widely used 7.62 ×51 mm projectile types (M80, M61, P80/1, M80A1, M1158, and M993) were subjected to the analysis in this paper. Numerical simulations (Ansys Autodyn) of projectile impacts on hard steel targets were performed as part of this analysis. Projectiles had the same impact velocity (800 m/s). This allowed evaluation of the projectile’s design and material’s effect on its performance against a hard steel target. Validation of the numerical model and used materials was first performed, using available experimental data. A short description and Computer-Aided Design (CAD) model of projectiles is also given. Comparing the M1158 projectile to other AP projectiles taken into consideration, it was concluded that the former had a much deeper penetration depth into a hard steel target (Armox 500T). The projectile’s penetrating capability is greatly impacted by the material selection used for its component parts. Assuming all other factors remain constant, penetrators with higher density and harderness can achieve deeper penetration. Under the same conditions, an increase in penetrator length results in an increase in penetration depth. The absence of a gilding metal jacket in the projectile’s frontal ogive section can decrease energy required to remove the jacket during the penetration, hence increasing the projectile’s penetration capabilities.
