Optimization of the structure of turbine blades produced by methods of additive technologies

Abstract

This study is devoted to the analysis of methods for optimizing the process of manufacturing turbine blades using additive technologies, taking into account the factors of external and internal influence on the finished product, determining the parameters for manufacturing the part, as well as the technical and technological aspects of additive manufacturing of the part. The validity of this integrated approach lies in the complexity of production and the extreme nature of the operation of the part itself, which makes it impossible to accurately estimate the duration of the operation period. But the ability to additively manufacture turbine blades with precise final characteristics will allow the production of a high-quality part with a predictable operational process. In view of these requirements, the authors give recommendations on the criterial and algorithmic support of the process of optimizing the manufacture of a gas turbine engine blade. As a result of the research, it was concluded that the main criterion for optimizing the shape of a gas turbine engine blade is to maintain a constant distance between the corresponding boundary points of the blade sections. Therefore, it will be more efficient and expedient to optimize not the shape of the blade, but the composite from which it is made.
