In the conditions of modern operations with the enemy’s use of high-precision weapons, the amount of average daily losses of armored weapons and military equipment (BTOT), for example, in the compounds and parts of the OUV, which conducts the operation, can reach 7-10%, and losses in the first day alone – 20 – 25%. This amount of losses of BTOT units and parts of the OUV may lead to the fact that after 3-4 days of the operation they may become limited in combat capability and may not complete the combat tasks assigned to them in full. Therefore, the system of complex repair of damaged BTOT samples will play a major role in maintaining the combat capability of troops during the operation. This causes the need to develop requirements for the production capabilities of this system, in particular, for its main element – the system of repair (repair and restoration) bodies, thanks to which the system under consideration would be able to meet the needs of the troops in the conditions of modern operations. These requirements are related to the determination of the necessary average daily productivity of repair bodies for the repair of one or another type (group) of weapons and military equipment (OMT), the required number of repair departments (platoons), the labor intensity of a certain type of OMT repair, the probability of developing the OMT repair fund, etc. The purpose of this article is to propose a methobability apporoach to the substantiation of the indicators that characterize the system of repair of armored weapons and equipment of an operational group of troops, which takes into account the influence of the main external factors on the process of repair of armored personnel carriers. This is the approach allows you to determine the main indicators that characterize the studied system with sufficient completeness. Keywords: maintenance and repair system, armored weapons and military equipment, repair and restoration bodies.

The article describes the technology of building elements of unmanned aerial vehicles (UAV) based on the use of additive technologies (AT). AT opened a fundamentally new direction in the concept of UAV manufacturing, which makes it possible to obtain a final product of a given shape and size based on a digital prototype. The modern equipment used in JSC is constantly being improved and allows for high printing speeds to increase the quality of the product at relatively low costs. The use of AT makes it possible to significantly reduce the weight of UAV elements due to the reduction of material costs. The article examines the technological process of 3D printing of UAV elements and the technological scheme of materials selection for the manufacture of UAV elements. In the course of the conducted research, a number of problems related to the need to improve the process of 3D printing of complex elements of UAVs, in order to effectively use the latest additive 3D printing technologies in modern production in combat conditions, were identified. The results of test printing, plastic tests and calculations made it possible to develop a general methodology for the production of UAV elements using additive technologies. The introduction of additive technologies for the production of UAV elements in the field will contribute to solving a wide range of combat tasks. It has been established that the use of additive technologies will entail the adjustment of UAV design principles, the development of printing technologies, the use of new construction strategies, the emergence of new technologies related to 3D printing. The analysis of quality control mechanisms for the development of UAV elements shows that the technological scheme for the selection of composite material is an important element in the 3D printing of modern UAVs and their components. 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.
