Abstract

This paper describes the flutter property of elastic system with multiple modes based on a conventional modal complex eigen-value analysis. The flutter is, in conclusion, almost covered by a fundamental lowest-mode combination of heaving and torsional modes even though the target mode of flutter seems to be a higher mode than the lowest one.
