摘　　要：对Jorgensen非圆截面弹体的计算公式进行了验证 ,推导出适合于矩形截面弹体的计算公式 ,并对两个具体外形进行了计算。计算结果和风洞实验结果比较 ,法向力系数误差在 10 %以内 .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.
