摘　　要：采用数值计算方法,对不同翼展长度的巡飞弹模型进行数值模拟,从弹体各个部件的气动力贡献和流场特性两个方面对计算结果进行分析,结果表明:在亚音速条件下,随着翼展长度的增大,模型的轴向力系数和法向力系数增大,俯仰力矩系数减小;翼展长度的改变,还对弹身和尾翼座的气动力产生影响,随着翼展长度的增大,弹身和尾翼座的轴向力系数减小,弹身的法向力系数略有增加,尾翼座的法向力系数的变化较为复杂。通过对流场特性的分析,发现弹身收缩段产生涡。涡的大小和位置与变翼展长度的增大有关,弹身和尾翼座的气动特性也发生变化。This paper numerically simulates the model of patrol missiles with different wingspan lengths.The aerodynamic contribution and flow field characteristics of each component of the missile body are analyzed.The results show that,under subsonic conditions,the axial force coefficient and normal force coefficient of the model increase with the increase of the wingspan length,while the pitching moment coefficient decreases.The change of the wingspan length also has some influence on the aerodynamic force of the missile body and the tail seat:as the wingspan length increases,the axial force coefficients of the missile body and the tail seat decrease,and the normal force coefficient of the missile body increases slightly.The change of the normal force coefficient of the tail seat is complicated.Through the analysis of the flow field characteristics,it is found that the contraction section of the missile body yields vortices.Vortex size and position change with the increase of the wingspan length,and,as a result,the aerodynamic characteristics of the missile body and the tail seat also change.
