“…Современные требования к обеспечению заданной работоспособности всех видов техники определяются, с одной стороны, необходимостью поддержания требуемого уровня надежности и безопасности эксплуатации [1], с другой, соблюдением экономических характеристик их эксплуатации и ремонта [2]. Для газотурбинных двигателей (далее -ГТД) деталями, обеспечивающими выполнение указанных требований, являются, в первую очередь, лопатки компрессоров и турбин, подшипники, шестерни, уплотнения.…”

The study objective is to develop the scientific foundations for the practical implementation of new methods of serial repair of resource-saving parts with erosion-resistant nanocoatings, which are subjected to increased erosion wear in operation. The problem to which the paper is devoted is to study the reliability and technical effectiveness of the developed proposals for making additions to the current regulatory and technological documents for the serial overhaul of gas turbine engines. For the study the following methods are applied: application of ion-plasma coatings in vacuum, destructive (measurements of micro-hardness and erosion resistance of coatings) and non-destructive (instrumental) control, manual and other surface treatment of the studied parts, mathematical statistics and expert judgement while conducting and analysing experimental research results. The novelty of the work is in the use of information about compressor blades with multi-layer, multi-shade reinforcing nanocoatings worn out in operation during subsequent repair. Their application should be fixed in the reporting production repair documents during the previous repair of the same blades. Study results: confirmation of the defined resource characteristics of compressor blades, reduction of production defects during the repair of blades with remnants of high-strength nanocoatings, preservation of the conditions for ensuring the serial overhaul of gas turbine engines. Conclusions. The theoretical calculations and practical studies of the proposed methods for repair of resource-saving components with multilayer multi-shade protective nanocoatings provide both the specified requirements for the operational reliability of gas turbine engines and the serial overhaul.

Methodological foundation and back-ground technology, providing function-oriented properties of the structure of gas turbine engine components, are presented. A composition of the components for an integrated multi-connected technological process, providing functionally oriented properties of the gas turbine engine structural units, is given. The article presents data for improving gas turbine engine serviceability on condition that equal operational properties are provided through functionally oriented properties of the components and subsystems due to special coatings.
