Title (EN) ROTOR STAGE OF AXIAL TURBINE WITH AN ADAPTIVE REGULATION TO DYNAMIC STRESSES
(FR) ÉTAGE ROTORIQUE DE TURBINE AXIALE, À RÉGULATION ADAPTIVE AUX CONTRAINTES DYNAMIQUES
Abstract:
(EN) Rotor stage of an axial turbine comprising a plurality of vanes and a plurality of attenuators interposed between each pair of subsequent vanes, said attenuator impeding the rotation of the vane profiles caused by the centrifugal force during the operation and achieving a stiffening of the rotor vane array.
(FR) La présente invention concerne un étage rotorique de turbine axiale, comprenant une pluralité d'aubes et une pluralité d'atténuateurs intercalés entre chaque paire d'aubes subséquentes, ledit atténuateur gênant la rotation du profil d'aubes due à la force centrifuge lors du fonctionnement et assurant un renforcement de l'ensemble d'aubes rotoriques.
