VIBRATION DAMPENING FOR LONG TWISTED TURBINE BLADES

Lashing long twisted turbine blades in groups with a small V-shaped gap between the groups, which tends to close due to the untwisting of the blades, when they are subjected to high centrifugal forces, provides a substantially continuous lashing ring with good vibration dampening characteristics, wh...

Beschreibung
Zusammenfassung:	Lashing long twisted turbine blades in groups with a small V-shaped gap between the groups, which tends to close due to the untwisting of the blades, when they are subjected to high centrifugal forces, provides a substantially continuous lashing ring with good vibration dampening characteristics, which is sufficiently flexible to allow for thermal expansion and contraction, and cooperates with the vibration reducing characteristic of joining the blades into groups to minimize stress vibrations in such blades.
