In recent years, there have been significant breakthroughs in aeroengine blade technology. These advancements are of great significance for improving engine performance and extending service life.
Recent years have witnessed significant breakthroughs in aviation engine blade technology, advancements crucial for enhancing engine performance and extending service life.
In terms of materials technology, high-temperature alloys, the key material for manufacturing aviation engine blades, have undergone continuous development, from wrought, cast, directionally solidified, to single-crystal high-temperature alloys. Single-crystal high-temperature alloys, in particular, have advanced to the sixth generation, significantly improving the alloy's hot corrosion resistance and high-temperature strength through the addition of specific elements such as rhenium. Furthermore, research and development of new high-temperature resistant materials are underway, promising to further enhance the temperature capacity of turbine blades.
In manufacturing processes, the advent of ultra-fast laser micro-machining technology has achieved a breakthrough in the "cold processing" of air film holes in aviation engine turbine blades, effectively addressing defects present in traditional manufacturing methods. Simultaneously, continuous improvements in precision casting and CNC machining technologies meet the demands for complex shapes and high-precision processing of blades.
In terms of performance testing and evaluation, the application of contact temperature measurement technologies, such as thin-film thermocouples, enables accurate measurement of blade surface and near-surface temperatures, providing crucial data support for blade structural design and service conditions. These technological breakthroughs have not only improved the overall performance of aviation engine blades but also driven the continuous development of China's aviation engine industry.
In summary, the breakthroughs in aviation engine blade technology are multifaceted and comprehensive. These advancements will collectively drive improvements in aviation engine performance and the transformation and upgrading of the aviation industry.
