The result of fuselage aerodynamic characteristics is important basic data in the research and development of helicopter.It is mainly obtained by two methods:CFD calculation and wind tun-nel test,and the results obtained by the two methods have some differences.Firstly,the CFD calcu-lation and wind tunnel test results of three different configurations helicopter fuselage models were compared.Then the correlation between two results was analyzed by the incremental method and the ratio method.The result showed that the difference between two results was basically the same at small angles,and the ratios of two results was basically the same at large angles.The research re-sults played an important role in improving the reliability and correction method of CFD calculation results.
