Patent

CA 2664257

A gas turbine engine reverse-flow sheet metal combustor for an aero gas turbine engine has a louverless single-piece liner design which includes a plurality of effusion patches, containing multiple rows of effusion cooling holes, bounded by cooled effusionless bands to aid in repairability of the combustor. The cooling of the bands improves the durability of the combustor and provides a method of repair for the combustor.

Chambre de combustion à flux inversé en tôle de turbine à gaz comprenant une doublure sans volet faite d'une seule pièce dotée d'une pluralité de zones d'effusion ayant plusieurs rangées d'orifices de refroidissement par effusion, reliées à des zones refroidies sans effusion pour faciliter la réparation de la chambre de combustion. Le refroidissement des zones favorise la durabilité de la chambre de combustion et permet de la réparer.
