Title
(EN) ROTOR ASSEMBLY FOR A GAS TURBINE
(FR) ENSEMBLE ROTOR DE TURBINE À GAZ
Abstract
(EN) The invention relates to a rotor assembly (RA), especially for a gas turbine, comprising at least a first rotor disc (FRD) and a second rotor disc (SRD), the two rotor discs (FRD, SRD) are arranged directly next to each other, wherein the first rotor disc (FRD) comprises a center through hole (CTH) and the second rotor disc (SRD) comprises no center through hole but a rotor disc center (RH). To control or to adjust the cooling air through gaps of a form-fitting torque transmitting means it is proposed to use a flow restrictor assembly (FRA) which restricts the effective flow cross section of the center through hole of the first disc (FRD).
(FR) L'invention concerne un ensemble rotor (RA), en particulier de turbine à gaz, comprenant au moins un premier disque de rotor (FRD) et un second disque de rotor (SRD), les deux disques de rotor (FRD, SRD) étant disposés directement l'un à côté de l'autre, le premier disque de rotor (FRD) comprenant un trou traversant central (CTH) et le second disque de rotor (SRD) ne comprenant pas de trou traversant central mais un centre de disque de rotor (RH). Pour commander ou pour régler l'air de refroidissement à travers des espaces d'un moyen de transmission de couple à complémentarité de forme, il est proposé d'utiliser un ensemble limiteur de débit (FRA) qui limite la section transversale d'écoulement efficace du trou traversant central du premier disque (FRD).
