A turbine engine includes an engine core extending along an engine centerline and includes a compressor section, a combustor, and a turbine section in serial flow arrangement. A turbine nozzle is arranged in the turbine section. Vanes of the turbine nozzle include a vane airfoil having cooling features formed in a trailing edge of the vane airfoil. Vanes of the turbine nozzle further include a baffle insert in a cavity of the vane airfoil. The baffle insert includes cooling holes.

Turbine engine with a nozzle having cooling features

In some embodiments, systems, apparatuses and methods are provided herein useful for spraying fuel in an augmented gas turbine engine. The embodiments may include a spray bar with a fuel injection aperture configured to inject a fuel jet into a fuel conduit; the fuel conduit having a fuel window to discharge the fuel jet into a core exhaust flow of an augmented gas turbine engine; a first channel directing a first air stream into the fuel conduit; and a second channel directing a second air stream into the fuel conduit. The first air stream and the second air stream cooperatively shape the fuel jet coming out of the fuel window.
