The necessity of improving the system of organization of accounting for the use of motor vehicles in military subunits, units and joint units of the National Guard of Ukraine is shown. For successful performance of assigned tasks by units, it is necessary to use the capabilities of motor vehicles to the maximum extent through rational planning of road transportation, to systematize the accounting and evaluation of the work performed by the vehicles To assess the performance and technical condition of motor vehicles, special indicators are used, which are a numerical expression of the measurements or their ratio, namely: fleet utilization factor; working time utilization factor; mileage utilization factor; load capacity utilization factor; speed, etc. However, they do not allow a generalized assessment of the level of efficiency of the use of vehicles. Therefore, there was a need to obtain a dependence for assessing the efficiency of transportation by military vehicles. It is proposed to improve the system of accounting for the use of automobile equipment in units and military units of the National Guard of Ukraine by introducing an indicator of the efficiency of loading and unloading operations It is proposed as an indicator of the efficiency of loading and unloading operations to use an indicator that allows you to assess the level of efficiency of transportation by determining the probability of cargo delivery at a given time.
The purpose of this article is to study the features of the usage of jet fuels for aviation gas turbine engines and the importance of the chymotology for the study of aviation kerosene and technical fluids usage in the of modern aviation technology. The role of practical aviation chymotology in ensuring reliable operation of aviation equipment and functional application of fuel and lubricants and technical fluids in existing and future aviation equipment is revealed in the work. In the present time jet fuels of both domestic and foreign production are supplied to meet the needs of the Air Force. The main tasks of chemical engineering are: the study of the processes that take place in the use of fuel on modern aircraft and the justification of requirements for the level of quality of aviation jet fuels and the assessment of the possibilities of its use, the development of the approaches of the optimization of the fuel quality, unification and standardization of quality assessment methods. Modern aviation jet fuels are produced from oil in the process of direct distillation on atmospheric tubule or on an atmospheric vacuum tubule and purification of the kerosene fraction with the addition of the necessary additives in order to improve performance. Thermal stability is important for jet fuels, especially for supersonic aviation fuels, since in modern aircraft with supersonic flight speed airfield heating of aircraft structures to high temperatures takes place due to adiabatic air compression in front of the aircraft. The surface temperature of the aircraft at a speed of 3 Mach can reach +330oC , and at 4 Mach can reach + 630oC. The main direction of improving the thermal stability of jet fuels, especially for supersonic aviation, is to improve the design of aircrafts and aircraft engines, as well as to improve the quality of jet fuels. The main ways of increasing of the thermal stability of jet fuels are changes in the technology of fuel production, an improvement of cleaning technologies, the use of more efficient additives, the use of fine filtration of nitriding of fuels and fuel pre-cooling. Keywords: fuel and lubricants, technical fluids, practical aviation chemistry, quality control, operational properties, gas turbine engine, efficiency and reliability of operation, physicochemical properties.
The analysis of the country's hostilities against the Russian occupiers and the existing state of providing troops showed the need to improve the management system of providing material means, weapons, and military equipment to military units based on a scientific analysis of the state of the troops, forecasting changes in circumstances, and decision-making. This requirement is largely satisfied by the implementation of the main mechanism of the management system at all levels of supply in the Armed Forces of Ukraine (AFU), namely the «feedback system». The implementation of such a system in the organization and management of the process of logistical (technical, rear and medical) support (MTZ) of training and combat use of the Armed Forces, which is currently in a state of conducting hostilities on the territory of the state, necessitates the development of a new concept of military information and material management - technical flows for use by a more effective structure, which is called the «military logistics system». A key element of the MTZ is a set of measures to accumulate stockpiles of material resources up to the established norms and provide military units and units with them in a timely manner, storage and maintenance in a state of constant readiness for use as intended. The purpose of the article is to determine directions for improving the management system of material resources, weapons and military equipment for their creation and accumulation in peacetime, rational echeloning at all levels of management for their timely and sufficient supply to military units during hostilities. Keywords: inventory management system, main mechanism, inventory, supply, material inventory, logistics, echeloning, operational accounting, inventory management process.
Planning of difficult logistic structures is presently conducted with the use of the special software products and modern information technologies. Presently in this area of widest find various computer expert facilities and systems of planning of processes of logistic. Large possibilities in this area are possessed by the packages of structural design. They allow not only to prepare the proper recommendations and projects on the base of exact analytical methods but also give them an evident, visual form. In this article the considered approaches of design of system dynamics of control of inventories in production-point-of-sale organizations which supply, material and technical facilities for Military Powers of Ukraine. The example of visual model of logistic chain is described developed at to the environment of package of structural design of iThink It is marked that work with the package of iThink does not require the special skills and knowledge of programming language. A model is developed by placing in a graphics editor separate component and them subsequent connection. If necessary intercommunications are set between separate knots. Analysing the package of structural design it is possible to draw a conclusion, that facilities of structural design of are some hard limits on the process of design. A model can be developed practically for any system of financial streams and supplies any the organizations of any pattern of ownership. Also it should be noted that design of activity of economic subjects exceptionally effective and perspective direction of development of administrative technologies. World experience testifies that computer analysis of the logistic systems, a condition is needed for the effective planning of creation and management similar difficult organizations Keywords: logistic system, system of logistical support of Military Powers of Ukraine, production-point-of-sale organizations, structural design.
The working process of the car is accompanied by the coupling of the wheel drive with the road, which is regulated by the coefficient of adhesion, which leads to the movement of the compressed part of the tire (stretching of the tire and its compression, which leads to the dynamic movement of the rolling arm of the wheel drive of the car. The article deals with the study of the movement of the deformed part of the wheel tire engine of a car using the theorem on the change of kinetic energy of this system, the general equation of dynamics. The purpose of the research is to improve the theory of the technological scheme of the wheel drive load with the detection of the movement of the deformed part of the movement of the car wheel drive and the connection of this movement with the movement of the rolling arm of the car wheel drive and the influence of the output parameters on this connection. The scientific and practical direction of the work consists in the fact that for the first time a technology was considered in which, during the rotation of the wheel drive, the points of the deformed part of the tire of the wheel drive of the car are displaced and the Coriolis force appears, which significantly affects the coefficient of adhesion of the wheel drive to the road. The methodology of the study was to establish a mathematical relationship between the coefficient of traction of the wheel drive tire and the road. As a result of the study, it was established: the influence of the initial parameters and the surrounding environment on the deformed part of the tire of the car's wheel drive is reflected in graphic dependencies; a change in the speed of the deformed part of the tire of the wheel drive causes the appearance of Coriolis acceleration, and for the appearance of Coriolis acceleration, the authors proposed a formula for calculating the acceleration of the deformed part of the car tire; the degree of dependence of the size of the deformed part of the tire on the size of the shoulder of the wheel of the wheel drive was established, and this degree is negative. Keywords: Coriolis forces, Coriolis acceleration, rolling shoulder, deformed tire part, wheel drive.
