Research on Aerodynamic Detection of Aero-engine Blade

The paper applies aerodynamic detection method to detect aero-engine nondestructively.In this paper,generating technology of elementary blade,optimization design of 3D blade,airflow parameter distribution criteria of blade surface,alignment between aero performance and blade geometry,numerical simulation method and method of blade research and analysis are tested.The paper validates the methods,improves the blade design and innovates the theory and practice of bla-de profile testing.
