Combustion chamber for turboreactor, has upstream and downstream orifices inclined tangentially at angle that is chosen in manner that air film formed by flow of air from upstream orifice is regenerated by air from downstream orifice

摘要

The chamber has an annular wall element (15) including multi-perforations constituted of an upstream orifice (15r1) and a downstream orifice (15r2). The orifices are inclined at an incident angle (Beta) on an axis (D) towards downstream of the chamber for passage of cooling air along an inner surface of the wall element. The inclination angle is chosen in a manner that an air film formed by flow of air from the upstream orifice is regenerated by air from the downstream orifice provided opposite to diagonal of a mesh network.
