우주비행체 비행성능 분석을 위한 CFD 공력해석

Aerodynamic coefficients of a re-entry vehicle are numerically investigated at various Mach numbers using a CFD cod. An adaptive grid method is utilized in order to enhance the accuracy of computational simulation. The force and moment coefficients are compared with available experimental data. It was found that the aerodynamic coefficients for various Mach numbers are in close agreement with the data.
