Comparative Study of Coupled-Mode Flutter-Analysis Methods for Fan Configurations

A comparative computational study of current flutter-analysis methods, for fan geometry in subsonic flow, is carried out to evaluate the relative advantage of the methods. The flutter characteristics are computed using the following three methods: time domain, work per cycle, and eigenvalue analysis...
