OUTER DIAMETER RAIL SUPPORT BEAMS

OUTER DIAMETER RAIL SUPPORT BEAMS

Vane assemblies (400; 500; 600) are described. The vane assemblies include a platform (402; 502; 602), an airfoil (410; 510; 610) extending from the platform, a forward rail (404; 504; 604) extending from the platform and arranged along a forward side of the platform, and an aft rail (406; 506; 606)...

Zusammenfassung:Vane assemblies (400; 500; 600) are described. The vane assemblies include a platform (402; 502; 602), an airfoil (410; 510; 610) extending from the platform, a forward rail (404; 504; 604) extending from the platform and arranged along a forward side of the platform, and an aft rail (406; 506; 606) extending from the platform and arranged along an aft side of the platform. At least one support beam (520; 512; 614a, 614b) is provided extending in a forward-aft direction between the forward rail and the aft rail and separated from the platform by a first distance. The at least one support beam has a thickness (T1) in a radial direction of 40% or less of a total radial extent (T2) from the platform to an outer diameter edge of at least one of the forward rail and the aft rail and the at least one support beam has a thickness (D1a, D1b) in a circumferential direction of 30% or less of a total circumferential extent (D2) of vane assembly.
