Abstract:

The blade tip timing (BTT) method has attracted increasing attention in the field of online detection of high speed rotating blade due to its outstanding advantages since it has been put forward. Based on the literatures published the basic principle of blade tip timing method is firstly described, both achievements obtained at home and abroad in recent years and research situations in this field are summarized. Secondly, several kinds of sensors based on BBT method and some new techniques for blade vibration parameters identification are analyzed and compared. Finally, research interests and difficulties in future study of this field are put forward.
