Trailing edge cooling for gas turbine airfoils
A hollow airfoil has a pressure side wall 12, a suction side wall 14, a cavity 16 formed between the pressure and suction side walls, a plurality of cooling ports 18 disposed within the pressure side wall 12, and a plurality of passages 42, each extending between the cavity 16 and one of the cooling...

| description | A hollow airfoil has a pressure side wall 12, a suction side wall 14, a cavity 16 formed between the pressure and suction side walls, a plurality of cooling ports 18 disposed within the pressure side wall 12, and a plurality of passages 42, each extending between the cavity 16 and one of the cooling ports 18. Each passage 42 has a first wall 54 adjacent the suction side wall 14, a pair of passage 58 side walls extending substantially toward the pressure side wall 12, and a second wall 56 adjacent the pressure side wall 12. Each passage further includes a pair of fillets 60,62 extending between the passage side walls 58 and the second wall 56. Alternatively, or in addition, each passage 42 includes a jog adjacent each cooling port 18 so as to extend parallel to the pressure side wall 12. |
