摘要
无人战斗机逃逸概率是无人机设计的重要指标之一,提高无人机飞行时的可用过载能够提高其逃逸概率,另外无人机的机动也对其逃逸概率有重要影响,如何评判在各种机动情况下无人机对导弹的平均逃逸概率与其过载的关系是无人机设计师和军方十分关注的问题;论文以带矢量推力无人战斗机(UCAVVT)作为研究对象,建立其飞行动力学及导弹导引飞行控制数学模型,通过预先假定无人机做典型机动的概率,由计算机仿真导弹与无人机的相对飞行轨迹,研究讨论在各种机动下UCAVVT在导弹攻击下的平均逃逸概率,并对计算结果进行了分析,得出了一些重要结论,对带矢量推力无人战斗机的总体设计具有一定的参考价值。
Evasive probability is one of the important targets to UCAV' s design. Moreover increasing the UCAV' s useable overloading in flight can enhance evasive probability, in addition UCAV' s maneuvers have main influence to its evasive probability. So the UAV' s designer and the military pay much more attention to the problem how to judge the relation between the UCAV' s evasive probability against the missile under a variety of maneuvers and its overloading. This paper considers UCAV with vector thrust (UCAVVT) as re search object, builds a flight dynamic model of UCAVVT and a flight control model of missile guide as research base. Assuming UCAVVT' s evasive probability under some representative maneuvers in advance, the relatively flight tracks between missile and UCAVVT are simulated by computer. Further, by discussing and analyzing results of UCAVVT' s average evasive probability against the missile under a varie ty of maneuvers, it presents some important conclusions which would have a certain reference value for the design of the UCAVVT.
