Apparatus for cooling turbine engine blade trailing edges

摘要

An airfoil (82) for a rotor blade (80) is provided. The airfoil (82) includes a pressure side wall (90). The airfoil (82) further includes suction side wall (92) connected to the pressure side wall at a leading edge (86) and a trailing edge (88). The airfoil (82) further includes plurality of first trailing edge slots (150) extending from the trailing edge along the pressure side wall and at least one second trailing edge slot (152). The plurality of first trailing edge slots (150) and the at least one second trailing edge slot (152) each include an inlet (162), an exit (168), and a length measured therebetween, the at least one second trailing edge slot has a length that is longer than a length of the plurality of first trailing edge slots.
