The current work presents the intermediate results of model development to assess the impact of various defects on the axial compressor operation. Recommendations for adjusting computational models are proposed to conduct gas-dynamic and strength studies of compressor stages and blades, taking into account various defects: verification for the presented models was carried out, which results are also presented in the paper. Based on the verification calculations results some features of CFD modeling are considered, as well as requirements for the investigated defects are indicated. The Discussion section presents the defects classification according to their influence on the compressor operation, which studying is possible using a specially developed mathematical description of blade profiles and blades geometry, as well as considering all the recommendations for computational model adjusting and a general approach to blades modeling defects.
