摘要
由于新技术的采用,现代飞机出现驾驶员诱发振荡(PIO)现象大大增加,因此PIO已成为危及飞行安全的主要因素之一。介绍了MIL-STD-1797A规范中的PIO预测准则和美国"人机耦合对飞行安全影响委员会"提出的准则,论述了这些准则要求的背景、机理和计算方法,最后以某机为例进行了PIO预测计算和分析。
The phenomenon of pilot-induced-oscillation(PIO) for modern aircraft is greatly increasing as using advanced technologies. Thus PIOs have been become one of the important factors to threaten flight safety. It is necessary to predict and analyse PIO in the top design phase for a new aircraft in order to avoid the PIO phenomenon. In the paper, some prediction criteria of PIO proposed by the United States 'Committee on the Effect of aircraft-pilot coupling on flight safety' are presented besides PIO prediction criteria in MIL-STD-1797A. The background, mechanism and analysis methods of these PIO criteria are emphatically presented. Finally the PIO prediction is calculated and analyzed for an aircraft as an example.
