中文摘要：
弹道表征导弹飞行状况，对导弹设计有重要作用。风是影响导弹飞行的重要因素之一。而计算机仿真对于生产及试验成本较高的导弹的开发定型等过程有着重要的作用。文中以常值风、阵风以及随机风为例，研究风对导弹飞行弹道的影响。首先建立无风条件下按231转动的地面发射坐标系中的导弹运动学、动力学模型，然后引入风的工程化模型，最后在Matlab环境中对某型导弹在风干扰下的弹道进行仿真，结合已有数据分析仿真结果。仿真结果表明，所得弹道基本符合实际，并证明风确实是影响导弹飞行弹道的重要因素。
英文摘要：
Missile trajectory characterizes the flight state of missile and is of great importance in the design of missile. Wind is a key factor that affects missile flight. Computer simulation plays a significant role in developing and finalizing the design of missiles whose manufacture and experiment are costly. The impact of wind on missile flight trajectory is studied, constant wind, gust and random wind serving as examples. Firstly missile kinematics and dynamics models without wind are constructed in earth-fixed coordinate system rotated by 231 method. Then the engineering model of wind is imported. Finally missile trajectory under the disturbance of wind is simulated in Maflab environment and the simulation result is analyzed combined with the existed data. The results of simulation conform that obtained trajectory is generally consistent with the actual and that wind plays an important role in missile flight trajectory.
