PROBLEM TO BE SOLVED: To provide an air shield to control an air flow to a fuel injector.SOLUTION: An air shield (100) for an injector (32) of a combustor (20) includes a first section (102) that extends axially from a first end (101) to a second end (103). The first section includes at least one side wall (105) and a top wall (107). The at least one side wall and the top wall at least partially define a channel (112) configured to distribute a channel airflow to the injector. The air shield also includes at least one first inlet (120) defined through the at least one side wall, and at least one second inlet (122) defined through the top wall. The at least one first inlet and the at least one second inlet are configured to receive a portion of a surrounding airflow to at least partially form the channel airflow.SELECTED DRAWING: Figure 1 |
