Abstract: Abstract. In the forcing of a low-pressure turbine (LPT) bladed disk, the final amplitude of the vibration state that sets in is determined by the dissipation produced by the friction forces at the blade-disk contact ...

Abstract: Abstract. Turbomachinery blade geometry deviates from design specifications because of the manufacturing process or degradation. These represent a source of mistuning, which can cause mode localization and amplified forced ...

Abstract: This work investigates the impact of acoustically treated intakes on fan flutter. The propagation of the fan acoustic perturbations is studied using a simplified model, where the frequency of the waves in the intake is the ...
