Abstract
The traditional method for obtaining aerodynamics coefficient for ejection seat is wind tunnel experiment. To research the feasibility of the application of computational aerodynamics coefficient for ejection seat on general CFD software, aerodynamics coefficient of ejection seat was computed using general CFD software. Through resolving fluid field, the result is obtained. The average difference of the result compared with the experiment data is less than 10 % and in the range of permission. It shows that CFD methodologies can be used instead of wind tunnel experiment for the ejection seat research. CFD methodologies can be applied widely to ejection seat research.
