In order to solve the problem of acquiring the digital model of axial compressors based on actual goods in the actual engineering projects, a Reverse Engineering procedure of the blade with high accuracy and efficiency by using Parametric Modeling was developed. Aimed at the requirements of geometric characteristics and aerodynamic optimization design of overall blade, a method of blade-measuring path planning based on curves of cross sections and blade body surfaces was presented. For solving the problems of difficulty in the definition and fitting in primary parametric surfaces and connections between them, a parametric surface definition method of typical axial compressors blade based on blade geometry characteristics was presented, and the connections were fit according to a process of “primary parametric surface boundary splicing surface generation”. Finally, integrated with an example of blades of axial flow compressors, parameterized reconstruction of the model was given, which proves that this method can satisfy the needs in engineering.
