“…As described in the previous paper by Fricke et al (2022), the data acquisition is performed through direct measurement, estimation or assumption based on the literature. The main base of LCI data was presented in a previous collaborative paper publication with colleagues from DTU focusing on Ti-Blisk manufacturing (Rupcic et al , 2022). This data has since been updated for the raw material and data on the Ni-Blisk was added (Figure 5).…”

“…Previous works on Blisk-LCA from our scientific working department focused on very basic preliminary results from small-scale Blisk by Bergs et al (2021) and a collaboration with DTU Copenhagen analysed potential benefits of Ti-Blisk recycling without going into technical detail and in-depth analysis (Rupcic et al , 2022). An in-depth assessment of full-size Blisk manufacturing is the focus of this study.…”

Purpose The aviation industry has seen consistent growth over the past few decades. To maintain its sustainability and competitiveness, it is important to have a comprehensive understanding of the environmental impacts across the entire life cycle of the industry, including materials, processes and resources; manufacturing and production; lifetime services; reuse; end-of-life; and recycling. One important component of aircraft engines, integral rotors known as Blisks, are made of high-value metallic alloys that require complex and resource-intensive manufacturing processes. The purpose of this paper is to assess the ecological and economical impacts generated through Blisk production and thereby identify significant ‘hot-spots’. Design/methodology/approach This paper focuses on the methodology and approach for conducting a full-scale Blisk life cycle assessment (LCA) based on ISO 14040/44. Unlike previous papers in the European Aerospace Science Network series, which focused on the first two stages of LCA, this publication delves into the “life cycle impact assessment” and “interpretation” stages, providing an overview of the life cycle inventory modeling, impact category selection and presenting preliminary LCA results for the Blisk manufacturing process chain. Findings The result shows that the milled titanium Blisk has a lower CO2 footprint than the milled nickel Blisk, which is less than half of the global warming potential (GWP) of the milled nickel Blisk. A main contributor to GWP arises from raw material production. However, no recycling scenarios were included in the analysis, which will be the topic of further investigations. Originality/value The originality of this work lies in the detailed ecological assessment of the manufacturing for complex engine components and the derivation of hot spots as well as potential improvements in terms of eco-footprint reduction throughout the products cradle-to-gate cycle. The LCA results serve as a basis for future approaches of process chain optimisation, use of “greener” materials and individual process improvements.

“…In addition to its role in climate change stemming from aircraft operations, the aviation industry bears responsibility for various other environmental issues associated with the supporting systems of aircraft, such as airports and fuel production, as well as all stages of its value chain, including aircraft manufacturing and disposal. Examples of these impacts encompass noise pollution, the limited use of rare metals (like cobalt or chromium in specialized alloys), and potential harmful effects from the release of chemicals, all of which have the potential to harm human health, ecosystems, and deplete natural resources [12,13]. The aviation industry has experienced steady growth in recent years until it was abruptly halted by the onset of the COVID-19 pandemic [14].…”

Thailand’s civil aviation industry has expanded rapidly in the past ten years resulting in increasing aviation greenhouse gas (GHG) emissions and energy consumption. The rapid growth in air transport is anticipated to continue further. Presently, domestic aviation and the economy of many countries are recovering rapidly in the post-COVID-19 period, resulting in fuel consumption and GHG emissions gradually increasing again. However, despite implementing the ICAO’s CORSIA (International Civil Aviation Organization’s Carbon Offsetting and Reduction Scheme for International Aviation) rule for international aviation, GHG emissions in the domestic aviation sector are largely unregulated. Moreover, the literature lacks a GHG emissions analysis that considers this sector’s potential growth and mitigation policies for future GHG emissions. To close the gap, this study conducted a GHG emissions analysis from this sector under various scenarios through 2050 using historical data during 2008–2020 to forecast future trends. It evaluates the impact of the mitigation policies, such as fuel switching and aircraft technology, on improving fuel efficiency due to technological advancements in aircraft and carbon pricing. The results show that the fuel switching option would result in a significant long-term reduction in GHG emissions, whereas the carbon pricing option and aircraft technology option are desirable in reducing GHG emissions in the short term. Therefore, to meet GHG emissions reduction targets more successfully, all measures must be simultaneously executed to address short- and long-term mitigation strategies. These findings have significant implications for both present and future GHG emissions reduction measures, supporting Thailand’s 2050 climate targets and energy efficiency policies as the domestic aviation industry adjusts.
