Abstract
Metallist-Samara JSC has developed a fundamentally new design of a unified double-circuit burner of a low-emission combustion chamber (LECC) of a ground-based gas turbine unit (GTU), adapted for manufacturing with the help of an innovative technology by selective laser melting (SLM) of metal powders using CAD models. Several batches of burners were made and control studies were carried out characterizing the quality of manufacturing according to the established procedure. Deficiencies inherent in the SLM process were discovered, the main of which are: raised roughness, in particular, of the fuel channels of the main and duty zones; microporosity, microalloying; microcracks; instability of flow characteristics; local non-sintering zones of the layers grown on the burner body. As a result of the analysis of the state of the manufactured burners, research and refinements, it was found that most of the identified shortcomings can be eliminated during further development of the modes and parameters of the technological process. Currently, difficult engineering problems associated with the implementation of additive manufacturing technologies have been overcome.
