Abstract: Bladed disks are critical parts of aeronautic turbojet engines requiring numerous dynamic analysis tests to fully achieve their design process. This work presents subspace state-space identification techniques for estimation ...

Abstract: Experimental methods are necessary to quantify structural damping. Among these methods, modal testing of bladed disks is of particular interest because it provides an efficient experimental characterization of these ...

Abstract: Due to an increasing need for efficiency of turbo-engines, rotor–stator clearances are being lowered. Therefore, new designs show higher probability for contacts between rotors and casings. When contacts occur, high dynamic ...
