“…In the construction of ACSV, one should take into account the elements of the "extreme modularity" postulate [15,16], which means redundancy of key components, power supply systems and information exchange channels enabling a) relatively quick repairs in field workshop conditions with the use of spare parts kits; and b) assembly of specialized equipment modules depending on the planned mission. It is necessary to pay attention to the necessity of maintaining the balance in the cost/effect relationship.…”

The idea of using unmanned platforms for combat tasks is progressing. The analysis of contemporary armed conflicts indicates that in the future, military operations will be largely carried out in urbanized areas. The article outlines the tactical conditions determining the operation of unmanned ground platforms on the urbanized battlefield and formulates tactical and technical requirements to be met by an autonomous combatsupport vehicle (ACSV) designed to cooperate with infantry subunits in contemporary and future military operations.

“…Warhead parameters and the combined damage capability of multiple projectiles determine damage efficiency. Many researchers have been interested in this topic for decades and have developed many models to study the maximum warhead fragment speed [1][2][3]. e Taylor formula [4] and the Shapiro formula are two commonly used models to solve axial fragment speed and fragment spatial dispersion.…”

Dynamic spatial distribution and killing characteristics of warhead fragments are important topics in the field of weapon effectiveness and protection. However, there is little research on the fragment distribution formed by continuous dynamic attacks of multiple projectiles that explode above the ground. This study analyzes spatial distributions of warhead fragments using witness boards in a rectangular target test. The results show that the fragment distribution of multiple projectiles in continuous dynamic attacks demonstrates a spatial superposition characteristic. The superimposed distribution is the sum of the distributions of two independent fragment distributions. The distribution characteristics are consistent with fragment scattering behavior. Therefore, they can be used to analyze the killing effects of multiple projectiles conveniently. The effects of falling speed, falling angle, and explosion height on the damage range of fragments were explored by a fragment spatial distribution model obtained from experiments. Analysis indicates that the prefabricated fragment distribution conformed to a spatial superposition relationship under dynamic multiprojectile continuous attacks, and the superposition obeyed fragment scattering characteristics. As the projectile falling angle increased at the explosion center, or as the falling height decreased, the positive pressure duration increased gradually. The falling speed had the greatest impact on the specific impulse of overpressure. The falling angle had the greatest impact on the peak value of overpressure. Both the falling angle and the explosion height had the greatest impact on the positive pressure acting time.

Explosion models based on finite element analysis (FEA) can be used to simulate how a warhead fragments. However, their execution times are extensive. Active protection systems need to make very fast predictions, before a fast attacking weapon hits the target. Fast execution times are also needed in real-time simulations where the impact of many different computer models is being assessed. Hence, FEA explosion models are not appropriate for these real-time systems. As a trade-off between accuracy and execution time, this paper creates a simulation of fragments from a warhead’s explosion, using simple analytical equations. The results are verified against explosion experimental data and FEA results. The developed model then can be made available for real-time simulation and fast computation.
