飞机涡轮发动机的振动数据,一直被认为是试车台测量的重要参数。但是,在飞行时进行这种测量是比较困难的。近年来,对飞行时进行振动测量的可靠性问题进行了大量研究。本文论述的是在飞行时振动数据处理的先进方法。已经证明,如果正确运用这一技术,就能为机组成员提供精确可靠的发动机转子不平衡信息。 Vibration data for aircraft turbine engines has long been considered an important parameter in test rig measurements. However, it is more difficult to make such measurements during the flight. In recent years, a great deal of research has been conducted on the reliability of vibration measurement during flight. This article discusses advanced methods of vibration data processing in flight. Proven application of this technique will provide crews with accurate and reliable information on engine rotor imbalances.
