Zusammenfassung:	A coolable airfoil 10 includes an internal cavity 18, an external wall 12, a plurality of first apertures 20, and a plurality of second apertures 20. The external wall 12 includes a suction-side portion 14 and a pressure-side portion 16. The external wall portions 12 extend chordwise between a leading edge 26 and a trailing edge 28. The first apertures 20, which are disposed in the external wall 12 adjacent the trailing edge 28, extend a distance within the suction-side wall portion 16 and exit the external wall through the pressure-side wall portion 14. The second apertures 22 extend through the pressure-side wall portion 14 and exit the pressure-side wall portion 14 upstream of and in close proximity to the first apertures 20.
