Aero-elastic Tailoring of Composite Turbomachinery Blades through Gradient-based Optimisation Ghent University
In recent years, advances in aircraft engine fuel efficiency have been largely the result of increased propulsion efficiency. The latter is obtained by increasing the diameter of the fan at the front of the engine, in contemporary designs responsible for most of the thrust. Further improvement is possible, but hindered by mechanical limitations of the fan blades, which are susceptible to aero-elastic flutter: severe vibrations created by a ...
