Abstract
The present disclosure is directed to a combustor assembly for a gas turbine engine. The combustor assembly comprises a volute walled enclosure defining a spiral scroll pitch axis disposed at least partially circumferentially around a centerline axis of the gas turbine engine, in which the walled enclosure is defined around the pitch axis, and the walled enclosure defines a combustion chamber therewithin.
Claims19
A combustor assembly for a gas turbine engine, the combustor assembly comprising:
- a volute walled enclosure defining a spiral scroll pitch axis disposed at least partially circumferentially around a centerline axis of the gas turbine engine, wherein the walled enclosure is defined around the pitch axis, the walled enclosure defining a combustion chamber therewithin;
- an outer casing surrounding the volute walled enclosure, and
- a plurality of inlet members positioned around the centerline axis, wherein the plurality of members defines an inlet opening at the outer casing in fluid communication with an upstream end of the volute walled enclosure,
- wherein a primary flowpath extends from a compressor section through a heat exchanger and into the inlet opening at the outer casing entering the combustion chamber and exiting through a turbine section, and further wherein the primary flow path extends from the turbine section through the heat exchanger.
