Title (EN) TURBINE AIRFOIL ARRANGEMENT INCORPORATING SPLITTERS
(FR) AGENCEMENT DE PROFILS AÉRODYNAMIQUES DE TURBINE INCORPORANT DES SÉPARATEURS
Abstract:
(EN) A turbomachinery apparatus (10) includes: a turbine (22), including: a turbine component (36) defining at least one arcuate flowpath surface (40); an array of axial-flow turbine airfoils (46) extending from the flowpath surface, the turbine airfoils defining spaces therebetween; and a plurality of splitter airfoils (146) extending from the at least one flowpath surface, in the spaces between the turbine airfoils, each splitter airfoil having opposed pressure and suction sides extending between a leading edge and a trailing edge, wherein the splitter airfoils have a thickness ratio which is less than a thickness ratio of the turbine airfoils.
(FR) L'invention concerne un appareil de turbomachine (10) qui comprend: une turbine (22), comportant un composant de turbine (36) définissant au moins une surface de trajet d'écoulement arquée (40); un réseau de profils aérodynamiques de turbine à écoulement axial (46) s'étendant à partir de la surface de trajet d'écoulement, les profils aérodynamiques de turbine définissant des espaces entre eux; et une pluralité de profils aérodynamiques de séparateur (146) s'étendant à partir de l'au moins surface de trajet d'écoulement, dans les espaces entre les profils aérodynamiques de turbine, chaque profil aérodynamique de séparateur ayant des côtés de pression et d'aspiration opposés s'étendant entre un bord d'attaque et un bord de fuite, les profils aérodynamiques de séparateur ayant un rapport d'épaisseur qui est inférieur à un rapport d'épaisseur des profils aérodynamiques de turbine.
