摘要
本文论述了BW-1变稳机空中飞行模拟H-7飞机发生两次纵向摆动时飞行状态特性,通过试飞研究其飞行品质,校核驾驶员诱发振荡(PIO)发生的可能性;并对解决PIO的方案进行了验证试飞研究,提出了排除PIO较适宜的参数值.试飞证明,空中飞行模拟试验是研究PIO的有效方法之一.
This paper deals with in-flight simulation of the behaviour of two longitudinal oscillations that occured on JJ-7 aircraft by using BW-1 variable stability aircraft. The main efforts include in-flight simulation research of JJ-7 flying quality under those two simulated special conditions check on the possibility to produce PIO, investigation of the way to solve PIO problem and defination of the parameter valule available to exclude PIO. It was confirmed that in-flight simulation test is one of effective ways to research PIO.
