  • DUAL-WALL IMPINGEMENT, CONVECTION, EFFUSION COMBUSTOR TILE
    Publication number: 20200025378
    Abstract: A gas turbine engine includes a combustor having a dual-wall impingement convention effusion combustor tile assembly. The dual-wall tile assembly provides a cooling air flow channel and attachments for securing the tile to the cold skin liner of the combustor. Cooling is more efficient in part due to the dual wall construction and in part due to reduced parasitic leakage, and the design is less sensitive to attachment features which operate at lower temperatures.
    Type: Application
    Filed: July 31, 2019
