Research on the Performance Evaluation of the High Maneuverability Flying Target Under Wide Scope Condition

考虑工程应用的宽域飞行条件是当前高机动目标开展总体设计和性能评估的挑战和难题。本研究选取当前研究热度较高的高超声速乘波体作为典型评估目标,建立涵盖5个学科共计16个关键指标的评估指标体系,并描述理论定义和判断准则。以此为基础,本研究考虑多个马赫数、多个攻角,以及多个舵偏角下的宽域条件,针对典型评估目标,建立性能评估流程,依据指标判据得出各性能的评估结果,并对总体性能形成分析结论。结果表明,本研究中提出的评估指标及流程方法能够有效地实现典型高机动目标的总体性能评估,得出具体性能的优缺点,满足宽域条件的分析需求,可为相关研究提供参考。

The wide scope flight conditions for engineering applications is a challenge and hard problem for overall design and performance evaluation of high maneuvering targets.In this paper,the hypersonic wave-rider is selected as the typical evaluation target.The evaluation index system is established,which covering 16 key indexes in five disciplines,the theoretical definition and judgment criteria are described.On this basis,the performance evaluation process is firstly established for typical evaluation objectives.Then,the evaluation results of each performance are obtained according to the index system.Finally,the overall performance is analyzed.Considering the wide scope conditions with multiple Mach numbers,multiple angles of attack and multiple rudder deflection angles,the performance evaluation process is established for typical evaluation target,the evaluation results are obtained by judgement criterion,and the conclusion of the overall performance is achieved.The results show that the proposed evaluation index and method can effectively realize the overall performance evaluation of typical high maneuvering targets.The advantages and disadvantages of specific performance can meet the analysis demands of wide scope conditions,and can provide reference for relevant research.
