Abstract：
There is increasing pressure on the aviation industry to priorities investment in green technologies that firstly produce reductions in CO2 emissions, and secondly, reduce noise. Modern gas turbines, notably high bypass ratio turbofan aircraft engines are continuously evolving to provide improved efficiencies for reducing fuel consumption and consequently, CO2 emissions. This presentation will focus on new advanced material and manufacturing technologies that enable efficiency improvements across a wide range of components for current and future large civil engines. One critical aspect is the use of high temperature materials and coatings for improvements in thermal efficiency. However, higher temperature operation, particularly for fast climb cycles can have adverse effects of component durability. The balance between efficiency and durability will be discussed with reference to intelligent cooling systems, robust component design and a full understanding of material behaviour. Other efficiency improvements will be highlighted such as those gained from advanced component manufacture, improved factory efficiency and a greater emphasis on sustainability through reduced material usage, improved material manufacturing yields, waste elimination, material recycling and component repair. Finally, a view of future green technologies for powering aviation will be shown.
