The article reveals the main capabilities, the availability and the condition of the existing samples of weapons, and the military equipment of the foreign production in the Armed Forces of Ukraine. They are supplied by the NATO member countries There is an effectiveness of their use as a part of combat units and the units of the Ground Forces of the Armed Forces of Ukraine, which carry out combat tasks to repel the armed aggression of the Russian Federation against Ukraine. The reasoned conclusions are also provided regarding the relevance of the study of the general structure, the order of preparation for using, maintenance and troubleshooting in the course of use during the combat work of crew foreign-made machines. The given quantitative and qualitative state of the existing domestic samples of the armored weapons and equipment are in comparison of the quantitative and qualitative state of the supplied machines. In addition, in the course of the analysis, samples of the equipment planned to arrive in Ukraine in the future are taken into account. The authors present a study of the set of probabilities of winning in elementary duels based on a comparison of the tactical and technical characteristics of the available weapons of both sides, which are available, as well as the probable frequency of use of the Armament and military equipment samples as intended. Some problematic issues faced by unit commanders after receiving and during the direct use of samples of the weapons and military equipment are given, as well as ways to solve them. Against the situation background, the Armed Forces of Ukraine are in relations to the supply of the necessary amount of armament and military equipment of the appropriate nomenclature from the state-owned enterprises of Ukrainian Defense Industries. The authors of the article also provide proposals that, according to experts in the Defense Industries, will increase the capabilities and improve the efficiency of the armament and the military equipment park of Ukraine in the coming years. Keywords: the state of the armament and military equipment, foreign-made technology, development prospects, increasing the efficiency of use, the possibilities of the armament and military equipment.
The article analyzes the ergatic system «man-machine-environment» in order to build a model of a combat tracked vehicle simulator as an element of the system «crew-combat tracked vehicle-combat situation-environment». A description of a simulated combat tracked vehicle is made as an object of control of the operator of a combat tracked vehicle simulator, as a subject of control with the definition of a person’s role in this system. In the course of the study, it was determined that the combat tracked vehicle simulator should be considered as a system with a complex internal structure. It is advisable to divide this system into two subsystems: the first subsystem is dynamic, this subsystem includes the dynamic platform of the simulator; the second subsystem is informational, in this subsystem the level of conformity of the conceptual model of machine control to the expected control result and the degree of achievement of the control goal is assessed. It should be noted that the dynamic and information subsystems are in constant close interaction with each other and determine the hierarchical structure of the simulator. The very same hierarchical structure of the simulator consists of two levels: dynamic and information-guiding. The directions of further research have been determined, which will ensure maximum correspondence between the simulated and real combat tracked vehicle. Namely, it is necessary to construct a spatial model of the movement of a combat tracked vehicle in a terrain with a complex profile, which will include modeling the oscillations of the vehicle body while moving on the surface of a complex profile and the dynamic effect of braking and acceleration of the vehicle on body oscillations. Keywords: combat tracked vehicle, operator, ergatic system, intelligent training system, system analysis, control object, control subject.
The article presents a method of increasing the survivability of unmanned aerial vehicles (UAVs) due to additive technologies (AT). The use of AT, namely 3D printing for the repair and printing of spare parts of UAVs during hostilities will significantly increase their survivability. It was determined that with the improvement of technological equipment and the development of methods of material selection for the manufacture of UAV elements, the direction of creating new UAVs with the help of AT will steadily expand. ATs provide an opportunity to obtain UAV elements of a certain shape and required size, even in field conditions, which significantly affects the survivability of UAVs. The use of AT makes it possible to significantly reduce the time for the recovery of UAV elements, as well as to reduce material costs. The cost of a printed plastic drone is much lower than similar models made of foam or carbon. In addition, thanks to such a body material and small dimensions, such a UAV will be inconspicuous for enemy radars. Another advantage of the technology is fast production. Russia's invasion of Ukraine revealed a number of problems related to the need to increase the survivability of UAVs and the need to use additive 3D printing technologies in combat conditions. The results of test printing, plastic tests and calculations made it possible to increase the survivability of UAVs whose components are manufactured using additive technologies. UAVs must have qualities that ensure their survivability and, above all, such qualities that would allow them to withstand the impact of enemy strikes. Such qualities are protection, combat resistance and reparability. Stability of operation of control systems, structural strength of UAVs, operational efficiency of UAVs will ensure that they perform a full range of tasks in accordance with their purpose. The use of AT contributes to the increase in the effectiveness of the combat use of UAVs by 1.5-2 times in connection with the reduction of the time for carrying out restoration and repair work. These calculations are confirmed by the practical experience of using AT during test and experimental flights. Keywords: additive technologies, UAV, 3D printing, technology, structure.
