Modernization of the pipeline element base of domestic aircraft in conditions of import substitution

The paper considers the problems of modernizing production processes for creating various types of pipelines for various systems of modern aircraft. Based on the analysis of the current state of affairs in the aircraft industry, proposals have been developed to increase profitability and reduce the duration of the production cycle of the aircraft element base. Ways are proposed to ensure the quality of the internal coating of pipelines in order to increase their reliability.
