Abstract

A turbine engine assembly includes an air swirler structure (66), an injector nozzle (108) and a nozzle guide (70). The air swirler structure (66) includes a swirler wall (82), an inner passage (134) and an air swirler passage (122). The swirler wall (82) includes a flow guide surface (92). At least an inner portion (110) of the flow guide surface (92) has a frustoconical geometry. The inner passage (134) extends axially along an axis (72) within the air swirler structure (66) to a swirler outlet (140). The air swirler passage (122) extends radially into the air swirler structure (66), longitudinally along the flow guide surface (92) and to the inner passage (134). The injector nozzle (108) projects axially into the inner passage (134). The nozzle guide (70) couples the injector nozzle (108) to the air swirler structure (66). The nozzle guide (70) is axially abutted against the swirler wall (82).
