Abstract

An apparatus for a gas turbine engine (20), such as an apparatus for a turbine exhaust section (49). The apparatus includes an airfoil (70) extending spanwise along a span line (72) from a base (74) to a tip (76). The airfoil (70) extends laterally between a pressure side (78) and a suction side (80), and the airfoil (70) extends along a chord line (82) from a leading edge (84) to a trailing edge (86). The airfoil (70) includes a slot (88) extending through the airfoil (70) from a slot inlet (94) to a slot outlet (96). The slot inlet (94) is disposed on the pressure side (78) and the slot outlet (96) is disposed on the suction side (80) The slot (88) defines a channel (98) for directing fluid flow from the pressure side (78) to the suction side (80) through the airfoil (70), such that the slot (88) will bypass the associated pressure losses from a blunt facing body.
