摘要
以某型激光制导航空炸弹为例,进行了三维动态数字仿真研究。建立激光制导炸弹空间六自由度运动方程组,激光制导炸弹控制系统数学模型和控制信号的形成模型,用拟合技术求解气动力因数,仿真计算了水平投放时的投放域,并对影响攻击区边界的因素和影响制导精度的因素进行了分析和讨论。对激光制导炸弹的研制提出了几点建议。
The paper makes a study of the three-dimensional dynamic digital simulation of a certain type of laser-guided aerial bomb and establishes the bomb＇s six-freedom space movement differential equations, control system mathematical model and control signal formation model. The approach technology is taken use of to solve get the coefficient of pneumatic force. By calculation and simulation, the bomb＇s dropping area in horizon has been got. Factors affecting the boundary of dropping area and the precision are also been analyzed. At last, some suggestion is provided for succeeding research of this kind of laser-guided bomb.
