战斗机“滚筒”机动的末端规避效果

Research on Effects of Fighter HGB Maneuvering Terminal Evasion

针对在线实时计算末端规避策略飞行员操纵难度大、规避效果差的现状,研究了战斗机HGB机动的末端规避效果。首先分析了HGB机动末端规避的原理;其次建立了HGB机动末端规避的数学模型;最后基于典型作战场景,研究了比例导引系数、导弹最大可用过载、制导回路延迟时间和弹目接近速度对HGB机动效果的影响,仿真得到导弹的脱靶量随HGB的机动角速度均呈先增大后减小的趋势。研究结果为飞行员选择合适的角速度范围做HGB机动末端规避时具有参考价值。

In view of the current situation that terminal evasion strategy of online real-time calculation control big difficulty and poor effect,and the effect of fighter HGB maneuvering terminal evasion is researched. Firstly,the principle of HGB maneuvering terminal evasion is analyzed. Secondly,the mathematic model of HGB maneuvering terminal evasion is set up. Finally,the influence of proportional navigation coefficient,most available overload,guidance loop delay time,missile-target approach speed to the effect of HGB maneuvering terminal evasion based on a typical combat scene. The simulation shows that the missile distance becomes bigger firstly and then becomes smaller as the change of angle rate on the various parameters. The results provide pilots reference when select suitable the range of angle rate to make HGB maneuvering terminal evasion.
