Turbomachine e.g. aircraft turbojet, combustion chamber, has internal and external flanges with orifices of triangular shape, where successive triangular orifices are arranged in staggered and head-to-tail configuration

摘要

The chamber has a chamber endwall (17) equipped with fuel injectors (32) and axisymmetric walls connecting the chamber endwall to internal and external flanges (18, 20) for fastening to internal and external casings (24). The flanges have annular portions that are pierced by orifices (30) for the flow of air to cool the downstream components, where the orifices of the flanges are of triangular shape. The successive triangular orifices e.g. isosceles triangles and equilateral triangles are arranged in a staggered and head-to-tail configuration. An independent claim is also included for a turbomachine such as an aircraft turbojet or turboprop comprising a combustion chamber.
