PECULIARITIES OF AUTOMATION OF MANUFACTURING A DETONATION MOTOR CHARGE

Abstract

The goal is to justify decisions regarding the automation of the manufacturing process of the detonation engine charge using a new technology 3D printing, which will ensure an increase in productivity and a decrease in specific energy consumption and material consumption during the manufacture of the charge. Method. Theoretical methods were used to substantiate the decisions regarding the automation of the process of manufacturing the charge of the detonation engine – analysis of existing solutions and their shortcomings, generalization of the research goal and its decomposition into local tasks, explanations on the condition of substantiation of scientific methods that are planned to be used in solving the tasks. The results. The analysis of existing solutions for automating the manufacturing process of the detonation engine charge and their shortcomings showed that there are solutions for the manufacturing of rocket engine components using 3D printing technology, but for solid fuel engines this task remains unsolved, in particular, due to the lack of a system approach that involves the integration elements of automation in technological equipment at a deep level. The analysis of the installation for the manufacture of a charge for a detonation engine as an object of automation showed that, under the condition of automation of the process of 3D printing of the charge, the physical properties of the material, different from those currently used, should be taken into account. In addition, the control of 3D printing must be coordinated with the control of the drying process of the deposited charge layers. Practical significance. The formed idea, goal and tasks of the research will allow to create a new approach to the automation of the manufacturing process of the detonation engine charge based on 3D printing technology. As a result, this will make it possible to create fast-acting gas-dynamic controls of an anti-aircraft missile, which is especially relevant for increasing Ukraine's defense capabilities.
