The Study of Acceleration-Based of Blades Tips for Blade Running Elevation Measurement
摘要
Abstract
The blade running elevation is an important experiment parameter in the helicopter blades dynamic balance experiment. It can affect the helicopter performances such as maneuverability and security. There are many disadvantages in old measure methods such as low precision, difficult measurement and immobile measurement point. Based on the analysis of blades dynamic characteristics, an approach of acceleration - based of blades tips is presented, the displacement of the blades can be obtained by second order integral in frequency domain and the difference of blade running elevation also can be obtained conveniently based on the displacement curve at the same time. Analysis of simulation shows that this approach can be used for blade running elevation measurement at random position of the blades rotation plane.关键词
