Apparatus for controlling contact within stator assemblies

A stator vane (40) for a turbine engine (10) includes a base (62) and an airfoil (60). The base is configured to couple the stator vane within the turbine engine. The airfoil extends radially outward from the base. The base includes a pair of circumferentially-spaced sides (90 and 91) coupled togeth...

Beschreibung
Zusammenfassung:	A stator vane (40) for a turbine engine (10) includes a base (62) and an airfoil (60). The base is configured to couple the stator vane within the turbine engine. The airfoil extends radially outward from the base. The base includes a pair of circumferentially-spaced sides (90 and 91) coupled together by an upstream side (92) and a downstream side (94), wherein at least a portion (110) of the base is recessed to facilitate reducing excitation responses of the vane during engine operation.
