Abstract
Airfoils (400; 500; 600; 700; 800; 900; 1000; 1100; 1200; 1300) for gas turbine engines (20) are described. The airfoils include an airfoil body having a leading edge and a trailing edge (414; 614; 714; 814; 914; 1114; 1214; 1314) extending in a radial direction, a cooling cavity (418; 618; 718) defined within the airfoil body at the trailing edge, and a plurality of angled pedestals (426; 526b; 626; 726; 826; 926; 1026) arranged along the trailing edge, wherein the plurality of angled pedestals define a plurality of angled trailing edge slots (431; 831) therebetween. Adjacent angled pedestals of the plurality of angled pedestals define a meter section (434; 834) of a respective angled trailing edge slot and a diffuser section (438; 838) of the respective angled trailing edge slot, wherein the meter section is defined by parallel sides of the adjacent angled pedestals, wherein the parallel sides of the adjacent angled pedestals are oriented at a bleed direction (D<sub>b</sub>) that is less than 90° with respect to a feed direction (D<sub>f</sub>) through the cooling cavity.
