Abstract
A transition duct having a panel assembly with an inlet end of generally circular cross section and an outlet end having a generally rectangular arc-like cross section is disclosed. The panel assembly has an uncoated internal profile substantially in accordance with coordinate values X, Y, and Z as set forth in Table 1. The coordinates are taken at a sweep angle Θ wherein Θ is an angle measured from the inlet end and X, Y, and Z are coordinates define the panel assembly profile at each angle Θ. An alternate embodiment of the invention defines an envelope for the uncoated internal profile of the panel assembly.
