| Popis: | The aviation industry has been growing continuously over the past decades. To ensure sustainability and competitiveness for the aviation industry sector, a full understanding of the environmental impacts is required, not only during use phase but along the entire life cycle, including “Materials”, “Processes and Resources”, “Manufacturing and Production”, “Lifetime Services” as well as “Reuse, End-of-Life and Recycling”. Core engine components, such as integral rotors (Blisks), are comprised of high value metallic alloys that require complex and resource consuming manufacturing processes. This paper will introduce an approach for Life-Cy-cle-Inventory data acquisition during Blisk manufacturing as basis for a Life-Cycle-Assessment (LCA) according to ISO 14040. A particular focus will be set on the data quality and confidence level regarding measuring, acquisition, and analysis of in- and output flows within the Blisk manufacturing process chain in scope. This includes the stages of material generation, forming processes, heat treatments, machining, surface treatments and quality assurance. A greater emphasis is drawn to selected variations on mechanical machining processes. On this basis, first results of an LCA for Blisk-manufacturing will be presented. |
