PROCESS FOR DEFINING HOLES FOR PASSING AIR THROUGH A COMBUSTION CHAMBER WALL

摘要

The invention relates to the placement of holes (25,27) for passage of air through a wall (3,5) of the combustion chamber of a gas turbomachine. Multiperforations are virtually positioned and distributed, including in a first safety zone without any air passage opening. The multiperforations of which a virtual entry or exit is located in this first security zone are virtually removed. Depending on certain criteria, then virtually at least some of said removed multiperforations are reintegrated, and, from then a perimeter passing through the virtual inputs and outputs of all the multiperforations present, is defined, in the direction of a primary hole or of dilution to be installed, a modified safety zone, then, respecting around said hole and with the freedom to reposition it within this limit, the shape of this hole is redefined.
