| 由于无人机技术的飞速发展以及无人机在现代战争中的作用越来越大，对无人机机载武器的需求越来越迫切。 本文充分借鉴美国最新研制的无人机制导弹药“短柄斧”，在关键部件结构特性分析的基础上，设计了一种新型无人机载灵巧子弹药，初步确定了其结构形状尺寸，并对配置杀伤、破甲战斗部的子弹药进行了结构特征数计算；基于 ANSYS FLUENT 软件对该灵巧子弹药的气动特性进行了仿真分析，获得了不同飞行速度下的升力系数与阻力系数；最后，对两种战斗部的威力进行了验证计算。 59536 毕业论文关键词 灵巧子弹药；结构设计；气动特性；威力 Title Structure Design of New UAV Smart Submunition Abstract Demands for UAV airborne weapons soars rapidly today which attribute to the development of UAV technology and the status of UAV is rising in modern warfare. The article takes "hatchet"—a new kind of UAV guidance ammunition the American has just developed as reference and based on the analysis of key structures, on the base of analyzing the key components of the structure characteristics, we design a new UAV smart ammunition, give a primary definition of its structure shape and size, the structure characteristic of the ammunition which configuration of the kill and shaped charge warhead, the fragmentation kill warhead calculated; The simulation analysis of the smart submunition aerodynamic characteristics were obtained based on ANSYS FLUENT software, gaining the lift coefficient and drag coefficient of different flight speeds; Finally, the power of the two kinds of warhead was verified by calculation.
