战术机动对飞机作战生存力的影响研究

Research on the influence of tactic maneuver on aircraft combat survivability

战术作为飞机生存力的影响因素,只被定性的提出。为定量化研究战术对飞机作战生存力的影响效果,以战术机动为例,建立了比例导引导弹在水平平面内对飞机的攻击模型;对飞机实施常规的盘旋机动规避导弹进行了仿真,验证了所建模型的合理性;假设机动的初始方向为随机量,采用蒙特卡罗方法,讨论了飞机实施超机动的初始距离与飞机生存概率的关系;在特定的机动初始距离上,研究了机动方向对脱靶量和生存力的影响。结果表明,在实施超机动之后,如飞机能获得100～300 m的初始距离和与导弹弹目线夹角成±70°～±120°的机动方向,则可以有效地降低飞机对导弹的敏感性,从而提高飞机在战场的生存概率。

As an influence factor, tactic is qualitatively proposed only. To quantitatively study this factor＇s influence on aircraft combat survivability, taking tactic maneuver for example, models of proportional navigation guided missile to attacking an aircraft are established in horizontal plane, whose rationality is validated through the simulation of that aircraft conventional circles to evade missile＇ s attack. Initial maneuver direction is hypothesized as a random parameter to discuss initial distance＇ s influence on aircraft survival probability after performing supermaneuver with the Monte-Carlo method. The impact of maneuver direction on miss distance and survivability is investigated on a given distance. The outcome indicates that if the aircraft get a distance between 100 - 300 m and direction whose angle between missile＇s line-of-sight is about ±70°～±120°after performing super-maneuver, it＇s susceptibility to missile can be effectively decreased, so that it＇s survivability is enhanced.
