Scientific technical progress demands of technologists decision of questions concerning cardinal improvement of quality of engineering products, and also providing of breakthrough aggregation of features and their practicality measure. In particular, it is necessary for hardware which works under severe operation conditions, and to features of which great demands are made. There are a lot of different functions which affect products in operation conditions. And these functions have variable action parameters. That fact in some cases leads to quick product function loss and to reduction of operating properties of machine or technological system. So, engineering products should be provided by unconventional properties [1, 2, . In order to resolve the problems we need nontraditional approaches in development of fundamentally new technologies. They should allow solving complicated problems of new generation of machines development with properties composition, got through application of different in significance technologies [.
It is shown that the compressor of a gas turbine engine consists of a group of blades which experience uneven abrasive-erosion wear characterized with unevenness of three types. To increase compressor blade life it is offered to use function-oriented coatings and to ensure their properties on the basis of the principle of equal resource. In the work there are solved the problems of a structural synthesis of a complex multi-coherent technological process of function-oriented blade group sputtering.
General features of technological engineering of a gas turbine engine with function- based properties of structural elements that provide an increase in its resource under the conditions of uneven operational impacts are presented. A general methodology of technological engineering of a gas turbine engine with function-based properties formed on the basis of a complex multi-connected technological process has been developed. In furtherance of the general methodology of technological engineering of a gas turbine engine, an algorithm for its implementation using an iterative-recurrent approach has been developed.
The paper reports the analysis carried out regarding the peculiarities in the formation of explosion functionally-oriented coatings. It is shown that their properties should be ensured depending on the action peculiarities of operation functions. A schematic diagram of a plant for coating sputtering is shown. Basic characteristics and technological peculiarities for the realization of functionally-oriented coatings in mechanical engineering are established.
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.
