Light weight swirler for gas turbine engine combustor and a method for lightening a swirler for a gas turbine engine

摘要

The disclosure is directed to a swirler body for a combustor of a gas turbine engine, where the swirler body includes an annular mount face which defines at least one pocket. The disclosure is directed to a swirler assembly for a combustor of a gas turbine engine, where the swirler assembly includes a swirler first body with an annular first mount face which defines at least one first pocket and a swirler second body with an annular second mount face which abuts said annular first mount face, where said second annular mount face defines at least one second pocket. The disclosure is directed to a method of lightening a swirl assembly for a combustor of a gas turbine engine, where the method includes defining at least one pocket within an annular mount face of a swirler body.

主权项

1. A method of lightening a swirler assembly for a combustor of a gas turbine engine comprising:
defining at least one first pocket within an annular first mount face of a first swirler body; defining a capture plate that is configured to retain a nozzle guide to include a non-circular inner periphery; extending said at least one first pocket through an outer surface of said first swirler body; and abutting the annular first mount face of the first swirler body with an annular second mount face of a second swirler body such that a primary combustion core airflow is configured to enter the at least one first pocket and at least one second pocket of the annular second mount face and be trapped therein and impinge within the at least one first pocket and the at least one second pocket but not be swirled or communicated toward a combustion chamber.
