Abstract

L’invention concerne la mise en place de trous (25,27) de passage d’air à travers une paroi (3,5) de chambre de combustion de turbomachine à gaz. On positionne virtuellement des multiperforations que l’on répartit, y compris dans une première zone de sécurité sans orifice de passage d’air. On enlève virtuellement les multiperforations dont une entrée ou sortie virtuelle se situe dans cette première zone de sécurité. En fonction de certains critères, on réintègre ensuite virtuellement certains au moins desdites multiperforations enlevées, et, depuis alors un périmètre passant par les entrées et sorties virtuelles de l’ensemble des multiperforations présentes, on définit, en direction d’un trou primaire ou de dilution à installer, une zone de sécurité modifiée, puis, en respectant autour dudit trou et avec la liberté de le repositionner dans cette limite, on redéfinit la forme de ce trou. Figure à publier avec l’abrégé : Figure 1
