this article deals with the problem of the influence of gas turbine equipment on its energy efficiency, environmental performance and acoustic properties of thermal mini heat power plants. Environmental aspects of the introduction of gas turbine technologies in heat and power industry are very important. The paper considers technological limitations of the wide use of gas turbine equipment and ways to solve them. The article discusses the developed original technology to improve the performance characteristics of parts that have exhausted their service life of aviation gas turbine engines, with the aim of using them as heat installations in heat and power engineering with improved acoustic performance. Constructive solutions are proposed for upgrading the serial installation of PVD coatings, for the possibility of applying nanostructured films according to the technology proposed in the article, with an increase in its economic and environmental performance.
