Comparison of Flutter Analysis Approaches in the Frequency Domain for the ECL5 Open Fan

Abstract The topic of this paper is the flutter analysis at part speed of the ECL5/Catana open fan. The focus is on the operating point of maximal pressure ratio on the 80% speed line, where previous studies have revealed a very high sensitivity of the aerodynamic damping for the...
