Claims20
An airfoil cooling circuit comprising:
- an impingement cooling circuit;
- and
- a serpentine cooling circuit.
An airfoil for use in a gas turbine engine, said airfoil having a cooling circuit comprising:
- an impingement cooling circuit;
- and
- a serpentine cooling circuit.
A turbine airfoil for use in a gas turbine engine, said airfoil having a leading edge, a trailing edge, and a plurality of internal cavities between said leading edge and said trailing edge, said cooling circuit comprising:
- an impingement cooling circuit disposed in an internal cavity near said leading edge and including an insert having a plurality of impingement holes;
- and
- a serpentine cooling circuit disposed in a plurality of internal cavities forming a serpentine path with at least two 180 degree changes of flow direction;
- wherein said impingement cooling circuit and said serpentine cooling circuit are in fluid communication and cooling air flows from said impingement cooling circuit to said serpentine cooling circuit.
