A method of producing a plurality of effusion holes (22) in a wall (20) of a combustor (16) of a gas turbine engine (10) comprises: determining a hole pattern definition which provides a functional relationship of the spacing between each adjacent hole within the row of holes (22); using the hole pattern definition to identify individual positions of the effusion holes (22) to be produced; and using a hole producing system to produce the effusion holes (22) at the identified positions.

L'invention concerne un procédé de production de plusieurs trous d'effusion (22) dans une paroi (20) d'une chambre de combustion (16) d'un moteur à turbine à gaz (10), le procédé comprenant les opérations consistant à: déterminer une définition de motif de trou qui fournit une relation fonctionnelle de l'espacement entre chaque trou adjacent à l'intérieur de la rangée de trous (22); utiliser la définition de motif de trou pour identifier des positions individuelles des trous d'effusion (22) devant être produits; et utiliser un système de production de trou pour produire les trous d'effusion (22) aux positions identifiées.
