Embodiments of a transition (400) of the present invention comprise a cooling channel (20, 30, 410) defined in part by an outer wall (23) and an inner wall (24). The cooling channel (20, 30, 410) also comprises lateral side walls (33, 34). Two or more subdomains (AA, BB, A, B1, B2, C1, C2, D) of imp

Embodiments of a transition (400) of the present invention comprise a cooling channel (20, 30, 410) defined in part by an outer wall (23) and an inner wall (24). The cooling channel (20, 30, 410) also comprises lateral side walls (33, 34). Two or more subdomains (AA, BB, A, B1, B2, C1, C2, D) of impingement jets (25, 35) are provided through the outer wall (23), and one or more metering outlets (26, 36, 37, 38) is provided through the inner wall (24), all communicating with a respective channel (20, 30, 410). The impingement jets of each respective subdomain are designed to supply cooling fluid to one of the one or more metering outlets. Further to the impingement jets (25, 35) their size, shape, spacing, and arrangement with regard to the metering outlet (26, 36, 37, 38) are such that a desired cooling of the inner wall (24) is provided during normal gas turbine operations through advantageous impingement cooling at points along the surface of the inner wall (24) that defines the cooling channel (20, 30, 410).

What is claimed is: 1. A transition for a gas turbine engine comprising:a tubular wall comprising an exterior surface, an interior surface, and defining a hot gas path interior to the interior surface;a plurality of channels disposed within the wall; two or more subdomains of impingement jets communicating between the exterior surface and one channel of said plurality of channels, each such subdomain comprising two or more impingement jets; andone or more metering outlets intermediate a length of the channel communicating between said one channel and the interior surface;wherein the impingement jets of each respective subdomain are designed to supply cooling fluid to only one of the one or more metering outlets;the transition being positioned between a combustion chamber can and a turbine of the gas turbine.
