摘    要:从简易制导炸弹的制导控制方案出发,分析了影响简易制导炸弹射程和精度的主要因素;给出了弹道设计所采用的弹道方程;建立了以方案机构产生的俯仰角突变时间t1、t2为设计变量,飞行距离为目标函数,满足控制精度、速度、法向过载和舵偏角等约束条件的方案弹道优化设计模型,并进行了数值仿真.数值仿真计算表明,按此优化设计模型得到的方案弹道,具有射程远、精度好的优点,方案弹道的优化设计除取决于方案机构给出的弹道倾角外,还将取决于投弹的初始条件.

关 键 词:流体力学  优化设计  方案弹道  简易制导炸弹

Abstract:Based on the guidance for a simply guided bomb, chief factors having impact on the range and accuracy of the bomb were analyzed. The ballistic equation adopted in the ballistic project design was derived. A mathematical model of ballistic project in accordance with restrictions of accuracy of control, velocity, normal overload and angle of yaw of the rudder etc, was established. In this model abrupt change of pitch angle t 1,t 2 depending on the control device are set as the design variables, and the range is set at the target function. Numerical simulation was performed. The results of numerical simulation of the model indicate that the maximum range is achieved and the accuracy of the bomb is satisfactory.
Keywords:fluid mechanics  optimization design  project ballistics  simply guided bomb
