摘要
现有的军用飞行品质规范针对不同种类飞机与不同飞行阶段,分别给出了其操稳特性的要求,但难以直接应用于指导军用飞机执行特定作战任务的飞行控制律设计。基于任务的飞行品质评定方法,以实际飞行任务的要求为依据来设计飞行品质评定的机动动作,通过地面模拟试验或飞行试验的客观试验结果,并考虑飞行员的主观评价来综合评定军用飞机的飞行品质等级。介绍了基于任务的飞行品质评定方法,讨论了评估机动任务的主要设计指标,给出了基于任务的飞行品质评定方法建立的近距空战、空中加/受油、对地攻击、舵面破损等4种典型任务/场景下飞机闭环响应特性的要求建议。通过对比分析阐述了这些要求与常规飞行品质评定准则的差异性及其应用的有效性。研究结论可为基于任务的军用飞机的飞行品质准则制定以及飞行控制律设计等提供理论参考。
Traditional aircraft flying qualities criteria provide requirements for stability and control characteristics of different military aircraft types in different flight stages, but it is hard to apply the criteria directly to the design of flight control laws for military aircrafts in specific combat missions. In the mission-oriented flying qualities evaluation approach, demonstration maneuvers are designed based on the requirements of the actual flight mission. Through the objective test results of ground simulation tests or flight tests, and considering the subjective evaluation of pilots, the flying qualities grade of military aircraft can be comprehensively evaluated. In this review paper, the process of mission-oriented flying qualities evaluation is introduced, and the main design indexes of the evaluation mission are discussed. The mission-oriented flying qualities evaluation method is applied to evaluate the flying qualities of aircraft in four typical missions and scenarios: short-range air combat, aerial refueling, air-to-ground attack, and control surface damage. The requirements of suggested closed-loop dynamic characteristics are given. In addition, the differences between these requirements and conventional flying qualities criteria are compared, and the effectiveness of these suggestions are analyzed. The research conclusions in this paper can provide a theoretical reference for determination of the mission-oriented flying qualities criteria and the flight control law design of military aircrafts.
