摘　　要：风的存在改变了末制导炮弹与空气的相对运动速度,导致末制导炮弹空气阻力和空气阻力加速度发生变化,与此有关的力和力矩也发生相应的变化.为了分析风的存在对末制导炮弹运动特性的影响特点,必须建立相应的弹道模型.在末制导炮弹标准弹道模型的基础上,主要考虑纵风、横风的存在,引入了相对弹道坐标系、相对速度、相对攻角、相对侧滑角的概念,分析力和力矩的投影,建立了有风条件下的末制导炮弹弹道模型.通过仿真分析,得出风对末制导炮弹的弹道影响规律,为末制导炮弹的弹道特性研究奠定基础.The existence of wind changes the direction and value of relative velocity between ter minal-guidance and air, which leads to the change of direction and value of air drag and air drag acceleration as well as the related forces and moments. In order to analyze characteristics of influence of the existence of wind on the motion features of terminal-guidance, ballistic model must be established. Based on the standard ballistic model, mainly considering w1 （range wind） and w2 （beam wind）, relative ballistic coordinate, relative velocity, relative angle of attack, relative angle of sideslip are introduced, and the projection of forces and moments are analyzed. Finally, the terminal-guidance ballistic model under windy condition is established. Through simulation, the rule of wind＇s influence on terminal guidance is obtained, which establishes the foundation for further research on its ballistic characteristics.
