... many solutions for improvement of High Cycle Fatigue lifetime of the blading. One of them is damping optimization through advanced design of parts. There are few main damping mechanisms occurring during blade vibrations: material damping, aerodynamical damping (usually below 0.3%) and frictional...

... in terms of stiffness and damping of the flexures. Five different fluidic channel geometry (circular, semicircular, inverse-semicircular, triangular, and inverse-triangular) with the same cross-sectional area was designed and fabricated inside of one-dimensional cantilever beam (10 × 30 × 100 mm 3...
