摘要
随着电传操纵系统在战斗机和民用运输机上的运用,驾驶员诱发振荡现象逐渐增加,对现代航空飞行安全构成直接威胁。介绍了Ⅰ型和Ⅱ型PIO的多种预测准则,重点研究了Ⅰ型PIO预测准则中的A准则、带宽准则和Neal-Smith准则,并对多型飞机的PIO趋势进行了预测。计算结果表明:A准则、带宽准则和Neal-Smith准则是预测PIO的有效方法。
The pilot-induced-oscillation for fighter and transporter was gradually increasing, as a fly-by-wire flight control system was widely applied. It has threatened modern aviation safety. Some prediction criteria of category I PIO and category 11 PIO were introduced. A criterion, bandwidth criterion and Neal-Smith criterion were analyzed and the PIO tendency of several aircraft was predicted by them. The calculation results show that A criterion, bandwidth criterion and Neal-Smith criterion are effective on PIO prediction.
