Patent ID: 7510371

Claim:
A turbine stator nozzle comprising: a row of vanes joined at opposite ends to outer and inner bands; each of said vanes having a concave pressure side and circumferentially opposite, convex suction side extending radially in span between said bands and axially in chord between opposite leading and trailing edges; said inner band being inclined outwardly between said leading and trailing edges and said outer band being correspondingly inclined more than said inner band, with said vanes having camber for turning combustion gases between said leading and trailing edges, and also having an acute twist angle for imparting swirl in said combustion gases discharged at said trailing edges; and said trailing edges being tilted forwardly from said inner band with oblique lean at said outer band to narrow said vanes in axial width at said outer band and correspond generally in axial width of said vanes at said inner band.
