  • Patent number: 4700544
    Abstract: A refilmer for placing the film of cool air impeded by combustion/dilution air holes of a combustor for a gas turbine engine includes a grommet with a lip extending axially in the combustion chamber. The outer side wall of the grommet is recessed in the area overlying the lip so that when assembled, it forms a gap with the liner exposing the lip to cool air for forming the film. Tabs on the cool air side prevent the grommet from falling into the combustion chamber. The aperture in the grommet is oriented to direct the combustion/dilution air stream at a relative angle to the flow of combustion products. Indexing surfaces on the grommet fixture locates the grommet to the liner prior to being welded into place.
