Abstract

Official abstract text for this publication.

An air and fuel injection system for the back of a turbomachine's annular combustion chamber, including a central injector and a peripheral annular fuel injector including at least one fuel injection aperture made in an annular wall and emerging in a peripheral annular channel separated from a central channel by the annular wall and having an annular space of admission of air. The system also includes multiple air ejection apertures made in the annular wall downstream from the fuel ejection aperture or apertures in reference to the flow of the air stream, for an additional injection of air into the channel.

First claim

Opening claim text (preview).

The invention claimed is: 1. An air and fuel injection system for the back end wall of a turbomachine's annular combustion chamber, comprising: at least two coaxial fuel injecting devices, said two coaxial fuel injecting devices including a central injector and a peripheral annular injector, the central injector emerging in a first channel designed for admission of a first air stream and having an aft outlet opened in a downstream direction for ejecting said first air stream so th…
