Title
(DE) GASTURBINENMASCHINE MIT EINEM GEDÄMPFTEN SCHAUFELCLUSTER
(EN) GAS TURBINE MACHINE COMPRISING A DAMPED BLADE CLUSTER
(FR) TURBINE À GAZ
Abstract
(DE)
Eine Gasturbinenmaschine umfasst mindestens einen Schaufelcluster (10), in dem mehrere Schaufelblätter (12) an einem gemeinsamen Innenring (14) und/oder Außenring (16) angeordnet sind. Der Schaufelcluster (10) weist wenigstens einen Hohlraum (18) auf, wobei im Inneren des Hohlraums (18) mehrere Dämpfungskörper (20, 22, 24) vorgesehen sind, die sich unabhängig voneinander relativ zu den Wänden des Hohlraums (18) und relativ zueinander bewegen können.
(EN)
A gas turbine machine comprises at least one blade cluster (10), in which several blades (12) are arranged on a common inner ring (14) and/or outer ring (16). The blade cluster (10) has at least one hollow space (18), inside which several damping elements (20, 22, 24) are provided that can be independently moved relative to the walls of the hollow space (18) and relative to one another.
(FR)
L'invention concerne une turbine à gaz comprenant au moins un groupe d'aubes (10) dans lequel sont disposées plusieurs aubes (12) sur une bague intérieure (14) et/ou une bague extérieure (16) communes. Le groupe d'aubes (10) présente au moins une cavité (18) à l'intérieur de laquelle sont placés plusieurs éléments d'amortissement (20, 22, 24) qui peuvent se déplacer indépendamment les uns des autres vis-à-vis des parois de la cavité (18) et les uns par rapport aux autres.
