Abstract

A fuel injector assembly for a gas turbine engine includes a swirler (64) and a fuel nozzle. The swirler (64) has an outer wall (80) having a SOW inner wall surface (140), an inner wall (82) having a SIW inner wall surface (120) and a SIW outer wall surface (122), an outer passage (86), and an inner passage (84). The SIW inner wall surface (120) includes first and second sections. The first section (120A) extends between a first airflow inlet (112) and the second section (120B), and the second section (120B) extends between the first section (120A) and an inner wall distal end (118). The first section (120A) tapers radially inward, and the second section (120B) extends parallel the center axis (70). The outer wall (80) circumscribes the inner wall (82) and extends axially along the center axis (70) to a distal outer wall end (138), and the distal end wall (118) is axially recessed within the swirler (64) from the distal outer wall end (138). The fuel nozzle projects into the inner passage (84).
