摘要:

着重从飞行控制系统角度谈有人驾驶飞机的驾驶员诱发振荡问题,分析了系统杆力、传动比、间隙、摩擦力以及飞控伺服作动器对驾驶员诱发振荡的影响,用矢量图简明地反映飞机产生驾驶员诱发振荡的可能性和趋势。对飞机飞行控制系统的设计和对驾驶员诱发振荡现象的分析、处理有参考价值。

关键词: 驾驶员诱发振荡, 飞行控制系统, 矢量

Abstract:

Pilot induced oscillation(PIO) of a piloted aircraft is described from flight control system(FCS) point of view. The effects of a system stick force, transmission ratio, clearance, friction and flight control servoactuator on PIO are analyzed. The possibility and tendency caused by PIO are concisely explained with a vector diagram, which is of value for reference in design of FCS and analysis of PIO.

Key words: pilot induced oscillation, flight control, vectors
