摘要
为研究随机风场和升阻比误差对空空导弹可攻击区的敏感度,基于某空空导弹模型与三维比例制导律以及随机风场模型等,通过大规模系统的导弹与目标对抗飞行轨迹仿真,迭代出了该空空导弹在各种(随机干扰)条件下的三维可攻击区.数值飞行仿真表明,随机风场和升阻比误差改变了空空导弹的可攻击区的形状和大小,这表明空空导弹的可攻击区对这些随机干扰具有较高的敏感度,当计算空空导弹的可攻击区时,必须考虑随机风场和升阻比误差,这具有明显的实际工程设计与空战应用的价值.
To study the sensitivity of attack zone of air-to-air missile influenced by random wind and error of lift-drag ratio, considering the error of lift-drag ratio, random wind model and so on, a great deal of numerical flight simulation was carried out to obtain 3D attack zones under all kinds of circumstance based on an air-to-air missile model and the 3-D proportional guidance law. The error of lift-drag ratio and random wind model were considered. The numerical simulation results show that the random wind and the error of lift-drag ratio distinctly influence the shape and size of attack zones. This shows that the attack zones of air-to-air missile are very sensitive to random wind and the error of lift-drag ratio. Therefore, random wind and error of lift-drag ratio should be considered while calculating the attack zones. This conclusion has the real importance for practical engineering design and air-to-air fighting.
