An airfoil core, comprising:
- a first core portion having a hybrid skin core, a tip flag core, and a trailing edge core;
- and
- a second core portion having a serpentine core and a leading edge core.
An airfoil, comprising:
- a body extending radially from a platform to a tip, axially from a leading edge to a trailing edge, and having a thickness between a pressure side and a suction side;
- a hybrid skin cooling passage arranged along the suction side;
- a tip flag cooling passage extending along the tip between the hybrid skin cooling passage and the trailing edge and in fluid communication with the hybrid skin cooling passage;
- and
- a trailing edge cooling passage extending from the platform to the tip flag cooling passage.
