Patent

CA 2449263

A gas turbine engine turbine stage (19) has an annular row of turbine airfoils (22) including a first plurality (41) of first airfoils (44) having a first chord length (CL1) and a second plurality (43) of second airfoils (46) having a second chord length (CL2) shorter than the first chord length. At least one of the second airfoils is circumferentially disposed between adjacent each pair (66) of the first airfoils. A second leading edges (47) of the second airfoils are located downstream of first leading edges (53) of the first airfoils. The first and second airfoils have different first and second temperature capabilities respectively and the first temperature capability is greater than the second temperature capability. The first and second airfoils may be made from different alloys and/or the second airfoils may be constructed to use lower amounts of cooling airflow than the first airfoils. More than one of the second airfoils may be disposed between each pair (66) of the first airfoils.

Un étage de moteur `turbine à gaz (19) possède une rangée annulaire de profils de turbine (22) comprenant une première pluralité (41) de profils principaux (44) avec une première corde (CL1) et une deuxième pluralité (43) de profils secondaires (46) avec une deuxième corde (CL2) plus courte que la première. Au moins un des profils secondaires est disposé en circonférence entre chaque paire (66) adjacente à chacun des profils principaux. Un deuxième ensemble de bords antérieurs (47) des profils secondaires est situé en aval du premier ensemble de bords antérieurs (53) des profils principaux. Les profils principaux et secondaires possèdent des capacités de température principales et secondaires, respectivement, et la capacité principale est plus grande que la capacité secondaire. Les profils principaux et secondaires peuvent être faits d'alliages différents et/ou les profils secondaires peuvent être construits de manière à utiliser un débit d'air inférieur aux profils principaux. Plus d'un des profils secondaires peut être placé entre chaque paire (66) de profils principaux.
