ABSTRACT:
A combustor includes spaced outer and inner liners defining therebetween a combustion zone, and having a plurality of circumferentially spaced tubular domes disposed between forward ends thereof. Each of the domes includes an annular inlet for receiving pilot airflow, a swirler having a tubular ferrule and primary swirl vanes for receiving the pilot airflow, and an outlet disposed in flow communication with the combustion zone. A pilot fuel injector is disposed in each of the domes for injecting pilot fuel into the pilot airflow for generating a pilot fuel/air mixture dischargeable from the dome outlet. A plurality of main fuel spraybars inject main fuel into compressed airflow channeled between the domes and the outer and inner liners for generating a main fuel/air mixture dischargeable concentrically around the pilot fuel/air mixture. And, the pilot fuel/air mixture is ignited for generating pilot combustion gases in the combustion zone which are effective for igniting the main fuel/air mixture for generating main combustion gases in the combustion zone.
