Abstract: Cooling air extracted from a gas turbine engine compressor is sent to nozzle vane cooling passage inlets, through the cooling passages, and to purge tubes of a set of two or more vanes. A mixing chamber formed between the purge tubes in a diaphragm cavity receives fluid from the purge tubes and directs it through exit passage(s) formed through a wall of the mixing chamber to a surface of the diaphragm. The exit passage(s) can be inclined to induce a fluid velocity component substantially parallel to the surface and/or in a rotation direction of a turbine wheel.

Abstract: Additively manufactured components including unitary bodies. The component may include a unitary body having a component section. The component section may include at least one passage extending at least partially through the component section. The unitary body may also include a supplemental section formed integral with the component section. The supplemental section may be disposed over the passage(s) of the component section and may include a channel extending at least partially through the supplemental section. The channel may be in fluid communication with the passage(s) of the component section. Additionally, the unitary body may include a transition conduit positioned within the component section and the supplemental section. The transition conduit may extend between the passage(s) of the component section and the channel of the supplemental section to fluidly couple the passage(s) and the channel.

Abstract: Cooling air extracted from a gas turbine engine compressor is sent to a nozzle vane cooling passage inlet, through the cooling passage, and to a purge tube of the vane. A mixing chamber formed in a diaphragm cavity receives fluid from the purge tube and directs it through exit passage(s) formed through a side wall of the mixing chamber and/or diaphragm cavity to a diametral surface of the diaphragm. The exit passage(s) can be inclined to induce a fluid velocity component substantially parallel to the diametral surface and/or in a rotation direction of a turbine wheel adjacent the diaphragm.
