Combustion system and method of assembling the same

A combustion system for a gas turbine engine, said combustion system comprising:

• an inner casing structure;
• an outer casing structure;
• and
• a combustion chamber frame mounted between said inner casing structure and said outer casing structure to at least partially define a forward boundary of a combustion chamber having a forward region and an aft region such that said combustion chamber frame is coupled to said inner casing structure and said outer casing structure closer to the forward region of the combustion chamber than the aft region of the combustion chamber, wherein said combustion chamber frame comprises a dome structure and a cowl integrally formed with said dome structure such that forward of said dome structure said cowl extends generally radially.

A combustion chamber frame for a gas turbine engine combustion system having an inner casing structure and an outer casing structure and defining a combustion chamber having a forward region and an aft region, said combustion chamber frame comprising:

• an inner frame segment;
• an outer frame segment;
• and
• an intermediate frame segment extending from said inner frame segment to said outer frame segment, wherein said combustion chamber frame is configured to be mounted between the inner casing structure and the outer casing structure to at least partially define a forward boundary of the combustion chamber such that said inner frame segment is coupled to the inner casing structure and such that said outer frame segment is coupled to the outer casing structure closer to the forward region of the combustion chamber than the aft region of the combustion chamber, wherein said intermediate frame segment comprises a dome structure and a cowl integrally formed with said dome structure such that forward of said dome structure said cowl extends generally radially.
