Modern aircraft engine design challenges are focused on increasing aircraft safety, lowering weight, optimizing manufacturing costs, and raising aircraft performance by expanding engine operating ranges. Within this frame, even though the design of thinner, lighter and highly loaded blades is an efficient solution to meet such requirements, new blade structures are more flexible and thus, are much more sensitive to unsteady physical phenomena such as fluid-structure or blade row interactions. Vibrations of high amplitudes might endanger the blade aeroelastic stability as well as its structural integrity. One of the main goal of aeroelastic investigations in turbomachinery is therefore:
The Institute of Aeroelasticity’s studies are focused on four main topics:
