空对空导弹对战斗机空战效能影响的仿真

Simulation of effect of air-to-air missile on operational effectiveness of fighter

定量分析了空对空导弹的装机数量、主要作战使用性能和机动能力对战斗机空战效能的影响,研究了作战过程中空对空导弹的有效使用方式,以提高战斗机的生存能力和空战效能.空对空导弹的动力学模型采用三自由度质点方程,典型运动轨迹分为分离、拉开、接敌3个阶段.同时给出了每个阶段对导弹轨迹的不同要求,在仿真中也考虑了导弹的雷达散射截面(RCS).采用一对一空战对抗形式,对幻影2000飞机与F16飞机在高空中距、携带不同数量的空对空导弹、以及在不同的时机使用等情况下,进行了空战仿真,结果表明载机速度、分离角度以及空对空导弹使用速度对战斗机的空战效能有很大影响.

Effect of quantity, performance and flexibility of air-to-air missile on airfight effectiveness was analyzed, and effective manner to use air-to-air missile in air action was discussed to improve fighter＇s survivability and its airtight effectiveness. Three degrees of freedom particle kinetic equations were employed to model the missile＇s motion, and typical trace of missile was partitioned into three different phases： breaking, parting, and contacting. Meanwhile, the different requirements of the missile trace were given in each phase; the characteristics of the missile radar cross section（RCS）were also taken into account in the simulation analysis. One-one airfight pattern was used to simulate a Mirage2000 vs. a F16 under circumstances of high altitude middle distance, different amounts of air-to-air missiles, various opportunities to launch missile, et al. Results show that fighter＇s velocity, disengagement angle and missile＇s velocity significantly affect the operational effectiveness of fighter.
