战斗机曲线跟踪数值仿真模型研究

Research on the Digital Simulation Model in Pursuit of a Fighter

建立了应用于空战数值仿真的战斗机曲线跟踪的数学模型。首先介绍了机动平面与瞄准平面的概念,给出了它们相重合的条件。导出了战斗机以调整速度进行曲线跟踪时的需用过载,及以最大转弯角速度进行曲线跟踪时的需用过载。根据导引运动学原理,讨论了战斗机为实现武器发射应进行的机动飞行。利用该模型对空战过程进行了数值仿真,仿真结果表明,所建立的数学模型是可行的。

The mathematical model in pursuit of a fighter which can be adopted in air combat digital simulation is built. The concept of planes of maneuver and aimming in the air combat is introduced, and the condition for two planes to meet is given. The required load factor of the fighter which is taking the action of pursuit at adjusting velocity or at maximum turn rate is probed. According to principle of guidance, the action for a fighter to fire is described. The mathematical model is adopted in the air combat digital simulation and the result indicates that the mathematical model is practicable.
