Turbine nozzle with CMC aft band

Abstract:

Flow path assemblies and methods for assembling such assemblies are provided. For example, a flow path assembly comprises a turbine nozzle segment including an airfoil extending axially between leading and trailing edges, an inner band defining a portion of a flow path inner boundary, and an outer band defining a portion of a flow path outer boundary. The airfoil includes a trailing edge portion defining the trailing edge and extending axially beyond the inner and outer bands such that the trailing edge is defined axially aft of the inner and outer band aft ends. The flow path assembly further comprises a shroud having a forward portion that extends axially along the trailing edge portion such that the forward portion defines the flow path outer boundary at the trailing edge portion. Methods of assembling flow path assemblies having a turbine nozzle assembly and inner and outer members also are provided.
