The 3-dimensional curved surface model was built by using parameterization method, and the process to divide the surface grids was packaged automatically. The new surface grids can be generated accurately and rapidly by changing the design arguments, thus the iteration efficiency in the scheme optimization process was improved. The aerodynamic performance was calculated by using the numerical method based on the Euler equation, the viscous correction was added in the analysis of the major scheme. The stealthy performance was estimated by using the high-frequency approximate method. The cruise status was taken as the design point to optimize the aerodynamic scheme considering the constraints of stealthy performance based on analysis-modification method, and the selected scheme was tested by the wind tunnel. The results prove the research deserving the selected scheme.
