The working environment of the high-pressure stage turbine blades in aircraft engines is extremely demanding, requiring unique and complex internal structures to meet various performance requirements such as cooling and strength. Blades manufactured using 3D printing by the team can easily achieve intricate internal cooling channels, complex film cooling holes, and other designs. These intricate structures can effectively enhance the cooling efficiency of the blades, reduce the working temperature of the blades, thus improving the thermal efficiency and reliability of the engine.
