Abstract
A stator vane is provided and includes an airfoil section, a banana foot section including a radially outermost surface and a fillet. The fillet is radially interposed between the radially outermost surface of the banana foot section and the airfoil section. Respective outermost peripheries of the fillet and the radially outermost surface of the banana foot section define first and second footprints, respectively, in corresponding axial and circumferential dimensions. At least a section of the second footprint extends beyond a corresponding section of the first footprint in at least one of the corresponding axial and circumferential dimensions.
