在充分考虑空地导弹发动机推力、气动力、燃料消耗、风场、视线角、过载和舵机延时等实际约束影响的基础上,建立了多条件约束下空地导弹攻击区计算模型;采用预估初始距离、高精度拟合导弹气动参数、自适应变步长法积分导弹运动方程、黄金分割法对距离进行寻优等措施提高解算速度;对该算法进行了数字仿真,结果表明:①随着目标进入角的增加,攻击区远界先增加后减少,并在180°时最大,0°时最小;②随着初速的增加,攻击区远界有所增加,但增幅不大;③随着高度的降低,攻击远界缩短了。

This paper establishes a mathematic model of computing attack area with limited condition after well considering engine’s thrust,atmosphere force,fuel consumption,wind,driving delay of rudder and other factors.In order to improve calculation velocity,the following measures is adopted,such as pre-esti-mate initialization distance,curve fit missile atmosphere parameter with high precision,adaptive variable step to integral missile kinematics equations and golden section method is used to find out near attack area and far attack area.Finally,the simulation is carried out.results indicate hiefly as fellow①attack area far distance climbs up and then declines with target entering angle's increasing,which reaches maximum at 180°degree and minimum at 0°degree;②attack area far distance gets something increase with initial veloc-ity,but the amplification is not obvious;③attack area far distance declines with altitude's drop.
