本文通过两种飞机操纵系统动态特性地面与真实飞行测试结果的比较分析,充分地论述了操纵系统质量不平衡(或配重)对系统和飞机(松杆)的动态特性的严重影响。事实表明,地面模拟试验研究操纵系统特性或与飞机组合的特性时,不考虑质量不平衡(或配重)的作用,可能导致研究结果的极不精确,甚至错误。对被试系统特性提出改善意见。在新机的设计中,利用质量不平衡的有盆效果,设计出性能较好的操纵系统。
In this paper, the comparative analysis of the test results of the dynamic characteristics of the two aircraft control systems and the actual flight test is carried out to fully explain the serious influence of the unbalanced mass (or counterweight) of the control system on the dynamic characteristics of the system and the aircraft (loose rod). Facts have shown that ground-based simulation studies that manipulate system characteristics or combinations with aircraft do not account for the effects of mass imbalances (or counterweights) that can lead to inaccurate or even erroneous findings. Improve the characteristics of the tested system. In the new machine design, the use of uneven quality of the basin effect, design better performance control system.
