AIR SHIELD FOR A FUEL INJECTOR OF A COMBUSTOR

摘要

An air shield (100, 200) for an injector (32) of a combustor includes a first section (102) that extends axially from a first end (101) to a second end (103), and a channel (112) defined by the air shield. The channel includes at least one inlet proximate to the second end. The at least one inlet is configured to receive a channel airflow (144) that is a portion of a surrounding airflow (44). The channel (112) is configured to control a distribution of the channel airflow (144) to the injector (32).
