摘要

摘要: 利用基础运动的航空发动机双转子模型实验台，分别对飞机在俯冲运动、偏航运动、横滚运动和俯冲-偏航耦合运动时双转子系统的振动进行测试，研究了机动飞行对反向旋转双转子系统动力特性的影响。实验结果表明：机动飞行在转子上产生的瞬态附加离心力和附加陀螺力矩将对转子的轴心运动轨迹和振动响应产生明显的影响。

Abstract: With a model experiment rig of aircraft engine dual-rotor system under base movements, the dual-rotor system vibration is tested when the aircraft is respectively in hovering, pitching, rolling and hovering-pitching motions. The influence of maneuvering condition over dynamic characteristics of the counter-rotating dual-rotor system is studied. The experimental results show that aircraft transient additional centrifugal force and gyroscopic moment generated in the internal rotor and the external rotor in rolling and pitching motions have a great influence on system transient vibration amplitude and axis center track.
