摘要: 基于传统的固体动力及涡喷动力战术导弹质量估算模型,建立以冲压动力远程战术导弹的燃料质量及起飞质量的迭代质量估算模型,同时建立将末制导纳入质量估算的改进估算模型。使用改进前后的质量估算模型分别对按照固定目标及运动目标设计的飞行任务剖面进行仿真,将2种模型计算出的质量估算结果与基准导弹飞行弹道结果进行了对比验证,定量分析了改进前后估算误差来源;同时研究分析了射程、目标运动速度、末制导启动距离、巡航高度对改进前后估算模型误差的影响,提出对于较近射程的固定目标或低速目标可以使用传统的末制导简化质量估算模型,而对远射程、较高巡航高度、较大末制导启动距离以及具有高运动速度的目标应考虑将末制导加入质量估算模型或对改进前的质量估算模型进行二次修正以减少估算误差。

Abstract: Based on the traditional mass evaluation model, an iterative evaluation model to study the fuel mass and the take-off mass of tactical scramjet missile is devised, and an improved evaluation model is put forward by taking terminal guidance into account. By comparing these two kinds of evaluation models for fixed and moving targets, the source of evaluation error is achieved. The influence of range, target speed, distance of terminal guidance and cruise height on evaluation error is discussed. The simulation results show that the traditional mass evaluation model which ignores the terminal guidance is suitable for short range fixed targets and low speed targets, while the mass-evaluation model considering terminal guidance or modified model ignoring the terminal guidance are suitable for long range, high cruise height, long-distance terminal guidance and high speed targets.
