STRUCTURE OF THE SYSTEM FOR MONITORING THE CONDITION OF NITROCELLULOSE POWDER DURING THEIR STORAGE PERIOD BETWEEN PRODUCTION AND DISPOSAL

The stability of powder charges based on nitrocellulose plays a decisive role in determining their service life. As the research analysis shows, in almost all countries of the world there is a problem of maintaining the properties of powder charges at the guarantee level. The properties of nitrocellulose powder charges are constantly changing, and a large part of them is in the post-warranty stage of storage. Changes in the properties of nitrocellulose powder charges can be such that they lead to man-made accidents and disasters, both when using them for their intended purpose and when they are stored in bases and warehouses. Thus, the task of assessing the state and forecasting the properties of nitrocellulose powder charges at the relevant stages of storage becomes relevant. This task is complex and can be solved using a well-known approach to solving such tasks, namely a monitoring system. In general, any monitoring system includes three main components: measurement of informative parameters; assessment of the current state based on the performed measurements; forecast. It is shown that the problem of storage and accumulation of a large amount of ammunition, namely powder charges, is characteristic not only for Ukraine, but also for such developed NATO countries as the USA, Germany, France, and the Czech Republic. There is evidence that in some countries a system of continuous monitoring of the state of ammunition has been introduced, but the research methods are imperfect and dangerous. To control the state of nitrocellulose powder charges, it is proposed to create a monitoring system. A structural diagram of the monitoring system is presented, which includes both already developed elements and those that require additional research and development. It is shown that for the effective operation of the monitoring system, informative indicators are necessary, which allow determining the state of powder charges without the use of complex diagnostic equipment. In addition, it will allow the creation of a database of powder charges for further monitoring of their condition throughout the entire life cycle. An approach to defining and substantiating new constituent elements of the oil refinery condition monitoring system has been developed.
