Abstract
Disks (e.g., compressor disk, turbine disk) are key components of aero-engine, which play an important role in flight safety. Over the past several decades, extensive studies have been carried out to study the modeling and detection methods of aero-engine disks with cracks. However, to the best of the authors’ knowledge, no comprehensive review has been reported yet to summarize the existing studies. In this paper, the dynamic models of disks with cracks are summarized firstly. Then, the crack detection methods are reviewed. Finally, the limitations and future trends are discussed, which can provide inspiration for future research.
