DYNAMICS OF MISTUNED RADIAL TURBINE WHEELS [PDF]
This paper presents investigations carried out at Holset into the dynamics of mistuned\ud radial turbine wheels, including a literature review, a lumped parameter model,\ud identification of the most responsive blade, distribution of the peak maximum order\ud response and a method of mistiming identification.

Mistuning Identification and Model Updating of an Industrial Blisk [PDF]
The results of a complete study of mistuning identification on an industrial blisk are presented. The identification method used here is based on a model-updating technique of a reduced order.

To develop turbomachinery blades with high reliability, it is indispensable to verify the natural frequency, damping, resonant stress, etc. under operating condition, and utilize these data in the mechanical design of a new blade.

Suppression of Nonsynchronous Vibration Through Intentional Aerodynamic and Structural Mistuning [PDF]
International audienceNonsynchronous vibrations (NSVs) arising near the stall boundary of compressors are a recurring and potentially safety-critical problem in modern axial compressors and fans.

A Modal Interpretation for Aeroelastic Stability Enhancement of Mistuned Bladed Disks
Understanding the mechanism of the aeroelastic stability improvement induced by mistuning is essential for the design of bladed disks in aero-engines. In this paper, a quantitative interpretation is given. It starts by projecting the mistuned aeroelastic

Aerodynamic Mistuning of Structurally Coupled Blades [PDF]
This paper discusses the impact of aerodynamic mistuning in the context of a structurally coupled blade system. The aerodynamic mistuning assumes a difference in blade loading (between adjacent blades) but no change in eigenfrequency or modeshape.

Temporal deployment of attention in musicians: Evidence from an attentional blink paradigm
Music training improves perceptual and cognitive skills, which may transfer to unrelated non‐musical domains. The cognitive processes and neural mechanisms enabling this transfer have yet to be discovered. Combining scalp recording of neuroelectric brain activity with an attentional blink paradigm, we provide evidence that music training improves the ...

Although bladed disks of turbomachinery are nominally designed to be cyclically symmetric (tuned system), the vibration characteristics of all blades on a disk are slightly different due to the manufacturing tolerance, the deviation of the material ...

Harmonic Mistuning of Blisks [PDF]
AbstractThe paper describes a new method to calculate the maximum amplificationof blade vibrations of a bladed disk or blisk subject to manufacturing tolerances. Two effects of mistuned blisks are analyzed in this paper. The separation of two orthogonal nodal diameters are shown and described in detail.
