采用数值仿真的方法计算了巡飞弹的结构特性,该巡飞弹具有栅格舵与扇式折叠翼,使用Patran软件建立结构模型,输入各部分结构材料属性,之后由有限元软件Nastran计算其固有模态。依据气动数据对巡飞弹的折叠翼进行了强度校核,采用Nastran进行静力计算,得出了在各马赫数下满足强度要求的最大飞行攻角。

The numerical simulation of structure characteristic of the cruise missile was performed. The cruise missile was equipped with grid fins and three fan folding wings. The structure model was made by the software Patran, all parts of the structure's material property were input, and then the intrinsic mode was calculated by the software Nastran. The intensity of the cruise missile's folding wing was checked based on the aerodynamic data, the static calculation was made by the software of Nastran, and the largest attack angle under various Mach numbers was obtained.
