| Abstract: | In this paper, an improved engineering method based on Jorgensen's method has been developed to compute normal force of missile with rectangular cross section. The calculated results are compared with the wind tunnel experimental data, and the calculated errors of normal force coefficient are less than 10%,the method is suitable for engineering preliminary calculation. |
