本文概述了闭环飞行品质研究的必要性,用跟踪试验进行闭环飞行品质研究的可能性和有效性。文中介绍了过去两次跟踪试飞的方法和结果以及存在的问题。为了克服这些问题,研制了一套跟踪显示系统,最近的一次闭环飞行品质研究计划中应用了这套系统。地面固定基座飞行模拟器试验和飞行试验表明,这套系统是有效的。试验结果还表明,用跟踪试验进行闭环飞行品质研究是成功的。文章就闭环飞行品质研究的好处以及尚存在的问题进行了探讨,并提出今后应进行的工作。主要是用已获得的飞行试验数据对驾驶员的数学模型进行识别和将跟踪试验的结果与其它飞行品质规范,包括开环判据和闭环判据,进行比较分析。
This paper summarizes the necessity of the research on the quality of closed-loop flight and the possibility and effectiveness of tracking test on the quality of closed-loop flight. The paper introduced the methods and results of the past two follow-up flight tests and the existing problems. In order to overcome these problems, a tracking display system was developed and applied in a recent closed-loop flight quality research program. Ground fixed pedestal flight simulator tests and flight tests show that this system is effective. The test results also show that using the tracking test to study the closed-loop flight quality is successful. The article discusses the benefits of closed-loop flight quality research as well as existing problems, and puts forward the work to be carried out in the future. It mainly uses the obtained flight test data to identify the driver’s mathematical model and compares the results of the follow-up test with other flight quality specifications, including the open-loop criterion and the closed-loop criterion.
