TURBINE SCROLL ASSEMBLY FOR GAS TURBINE ENGINE

A gas turbine engine includes a compressor section (130) and a combustion section with a scroll (224), a scroll baffle (250) , a combustor, and a combustor case. The scroll defines an interior scroll flow path. The scroll baffle (250) surrounds the scroll to define a scroll cooling passage (252). Th...

Beschreibung
Zusammenfassung:	A gas turbine engine includes a compressor section (130) and a combustion section with a scroll (224), a scroll baffle (250) , a combustor, and a combustor case. The scroll defines an interior scroll flow path. The scroll baffle (250) surrounds the scroll to define a scroll cooling passage (252). The combustor case (202) surrounds the combustor and the scroll baffle to define a collector space (270). Moreover, the engine includes a turbine section (150) with a turbine rotor (244) and a turbine rotor blade shroud (316) that includes a shroud cooling passage (320). The compressor flow path is fluidly connected to the scroll for cooling the scroll. Also, the scroll cooling passage (252) is fluidly connected to the shroud cooling passage (320) for cooling the turbine rotor blade shroud (316). Furthermore, the shroud cooling passage is fluidly connected to the collector space. Flow from the collector space flows into the combustor, along the interior scroll flow path, toward the turbine rotor (244).
