空空导弹射后动态可攻击区计算

The Calculation of Dynamical Attack Zone of Air-to-air Missile after Being Launched

为了获取群体飞行器攻防对抗中空空导弹发射后动态可攻击空域的信息,提出了射后动态可攻击区的概念并进行了明确的定义。基于某空空导弹数学模型(包括气动特性、推进系统及3-D比例导引律等),应用可攻击区的快速模拟算法,计算了一些典型情况的空空导弹射后动态可攻击区。数值仿真表明,射后动态可攻击区与发射时刻动态可攻击区的边界不同,并且射后动态可攻击区不一定位于发射时刻动态可攻击区之内。

To obtain the information of dynamic attack zone in real time online among engagements of flight vehicles, a new concept, dy- namic attack zone of air-to-air missile after being launched, was proposed, and the definition of the new concept was presented. Based on the mathematic model of an air-to-air missile which includes all sub-system models such as aerodynamic, engine, 3-D proportional naviga- tion guidance law and so on, some typical cases of dynamic attack zones of air-to-air missile after being launched were numerically simula- ted by very fast simulation algorithm （ VFSA）. The numerical simulation results show that the fight envelope of dynamic attack zone of air- to-air missile after being launched is different from traditional dynamic attack zone, and dynamic attack zone of air-to-air missile after being launched is not always inside traditional dynamic attack zone.
