The development trend of modern jet engines is driven mainly by fuel and thermal efficiency. Higher bypass ratios, higher pressure ratios, and thin, three-dimensional designed blades are necessary to achieve the former. These factors tend to increase the occurrence of flutter, which limits the operability of the jet engine.
This research aims to improve the general understanding of fan flutter by carrying out a root cause analysis of flutter for a modern low-pressure ratio transonic fans.
Visiting student projects
Research projects in collaboration with the Traf-Group at University of Florence focus on the effect of torsional content in combined flap vibration modes on aeroelastic stability.
