A transition duct (40) for a gas turbine engine (10) incorporating a combination of cooling structures that provide active cooling in selected regions of the duct while avoiding cooling of highly stressed regions of the duct. In one embodiment, a panel (74) formed as part of the transition duct includes some subsurface cooling holes (92) that extend under a central portion of a stiffening rib (90) attached to the panel and some subsurface cooling holes (94) that have a truncated length so as to avoid extending under a rib end (45). Effusion cooling holes...


The invention claimed is: 1. A panel of a transition duct for a gas turbine engine, the panel comprising: an upstream subpanel joined to a downstream subpanel; side subpanels joined along respective opposed sides of the upstream panel and the downstream panel, each side subpanel comprising a double bend region of the transition duct; and cooling structures formed in each of the side subpanels in only regions remote from the respective double bend regions. 2. The panel of claim 1, further comprising a distribution of effusion cooling holes reduced fro...
