COOLED COMBUSTOR FLOATWALL PANEL

摘要

A combustor floatwall panel includes a stack of layers of a sintered material forming in the aggregate a panel, an attachment stud, and a cooling flow passageway. The panel has a first surface and a second surface parallel to the first surface. The attachment stud projects from the second surface. The cooling flow passageway includes a feeder hole extending through the attachment stud, and at least one effusion cooling hole extending to the first surface. The effusion cooling hole is fluidly connected to the feeder hole. The effusion cooling hole extends along a first axis where the effusion cooling hole meets the first surface. The feeder hole extends along a second axis. The first axis is at a first angle relative to the first surface. The second axis is at a second angle relative to the first surface. The second angle is greater than the first angle.

1. A combustor floatwall panel comprising:
a stack of layers of a sintered material, which form in the aggregate: a panel having a first surface and a second surface parallel to the first surface; an attachment stud projecting from the second surface; and a cooling flow passageway that is made up of a series of apertures in adjacent layers, the cooling flow passageway includes: a feeder hole extending through the attachment stud; and at least one effusion cooling hole extending to the first surface and fluidly connected to the feeder hole; wherein the one or each effusion cooling hole extends along a first axis where the effusion cooling hole meets the first surface, the first axis at a first angle relative to the first surface; the feeder hole extends along a second axis through the attachment stud at a second angle relative to the first surface; and the second angle is greater than the first angle.
