Beschreibung
Zusammenfassung:	A stator vane support (100) with anti-rotation features is provided. The stator vane support (100) may comprise an inner diameter surface (105) opposite an outer diameter surface (107). The stator vane support (100) may comprise an anti-rotation lug (110) defining a protrusion extending inward from the inner diameter surface (105). The stator vane support (100) may have a first recess (120) defining a first void on the inner diameter surface (105) proximate a first surface (112) of the anti-rotation lug (110). The stator vane support (100) may have a second recess (130) defining a second void on the inner diameter surface (105) proximate a second surface (113) of the anti-rotation lug (110). The anti-rotation lug (110) may be configured to interface with a stator vane (180) to at least partially limit circumferential movement, and each recess (120, 130) may be configured to allow the stator vane (180) to thermally expand during gas turbine engine operation.
