TURBINE ENGINE COMBUSTOR HEAT SHIELD WITH MULTI-ANGLED COOLING APERTURES

摘要

A combustor for a turbine engine is provided that includes a combustor wall. The combustor wall includes a shell and a heat shield, which is attached to the shell. One or more cooling cavities are defined between the shell and the heat shield, and fluidly couple a plurality of apertures defined in the shell with a plurality of apertures defined in the heat shield. The apertures in the heat shield include a first aperture and a second aperture. An angle of incidence between the first aperture and a surface of the heat shield is different than an angle of incidence between the second aperture and the surface.
