For high-performance aircraft engines, the most difficult part of their development lies in materials and manufacturing processes, because performance requirements that exceed the limit will ultimately be implemented in the development of cutting-edge materials and manufacturing processes. Experts pointed out that the difficulties and performance gaps in my country's aircraft engine development are mainly reflected in the materials and processes of turbine blades and turbine disks. The most basic requirement for turbine performance in modern aircraft turbine engines is that they can work reliably and stably under high temperature, high pressure and high speed conditions. Among them, high-performance blades integrate advanced materials, advanced molding processes, advanced cooling technologies and advanced coatings.
