Claims
- 1. An airfoil, comprising:
- a pressure wall side and a suction side wall, extending widthwise between a leading edge and a trailing edge, and spanwise between an inner radical surface and outer radial surface, and wherein said side walls are bowed spanwise;
- a plurality of passages, extending spanwise between said inner and outer radial surfaces, disposed between said pressure and suction side walls;
- at least one passage turn, connecting said passages, said at least one passage turn including an end wall;
- a rib, separating said passages, having a rib end;
- wherein said end wall and one of said side walls acutely converge; and
- a first fillet, extending between said acutely converging side wall and end wall.
- 2. An airfoil according to claim 1, wherein said first fillet is substantially perpendicular to said one of said side walls.
- 3. An airfoil according to claim 1, wherein said first fillet is arcuate.
- 4. An airfoil according to claim 1, further comprising:
- a second fillet;
- wherein said rib end acutely converges with the other of said side walls, and
- said second fillet extends between said acutely converging side wall and rib end.
- 5. An airfoil according to claim 4, wherein said second fillet is substantially perpendicular to said other of said side walls.
- 6. An airfoil according to claim 4, wherein said second fillet is arcuate.
- 7. A stator vane, comprising:
- a pressure wall side and a suction side wall, extending widthwise between a leading edge and a trailing edge, and spanwise between an inner platform and an outer platform, and wherein said side walls are bowed spanwise;
- a plurality of passages, extending spanwise between said inner and outer platforms, disposed between said pressure and suction side walls;
- at least one passage turn, connecting said passages, said at least one passage turn including an end wall;
- a rib, separating said passages, having a rib end;
- wherein said end wall and one of said side walls arcuately converge; and
- a first fillet, extending between said acutely converging side wall and end wall.
- 8. A stator vane according to claim 7, wherein said first fillet is substantially perpendicular to said one of said side walls.
- 9. A stator vane according to claim 7, wherein said first fillet is arcuate.
- 10. A stator vane according to claim 7, further comprising:
- a second fillet;
- wherein said rib end and the other of said side walls acutely converge, and
- said second fillet extends between said acutely converging side wall and rib end.
- 11. A stator vane according to claim 10, wherein said second fillet is substantially perpendicular to said other of said side walls.
- 12. A stator vane according to claim 10, wherein said second fillet is arcuate.
- 13. A stator vane according to claim 10, wherein said first fillet is substantially perpendicular to said one of said side walls.
- 14. A stator vane according to claim 10, wherein said first fillet is arcuate.
