Turbomachine e.g. turbojet, for use in aircraft, has air guide including downstream end located at right side of dilution openings of inner wall of annular combustion chamber and at axial distance from air injecting unit

摘要

The turbomachine has a centrifugal compressor connected to an annular diffuser (312) to feed fuel to an annular combustion chamber (314). An annular inner casing (328) extends axially from the diffuser to an air injecting unit (346). An annular part (300) of an air guide made of sheet metal is driven by the inner casing, and extends around the inner casing to delimit with an inner wall of the chamber. The air guide includes a downstream end located at a right side of dilution openings (302, 304) of the inner wall of the chamber and at axial distance from the injecting unit.
