Abstract:
A transition duct having an inlet ring, an aft frame, and a panel assembly connecting said inlet ring to said aft frame, said panel assembly having an inlet end of generally circular cross section having a center and being connected to said inlet ring and having an outlet end of generally rectangular arc-like cross section connected to said aft frame, said panel assembly having an uncoated internal profile substantially in accordance with coordinate values X, Y, and Z at an angle &thgr;, as set forth in Table 1, said X, Y, and Z values carried only to three decimal places wherein said coordinates are relative to an origin at the center of said inlet end and taken at a sweep angle &thgr; that is measured from a first plane defined by said inlet end and increases toward a second plane defined by said outlet end, said planes intersecting at a line about which the angle &thgr; is measured, and X, Y, and Z are coordinates defining the panel assembly profile at each angle &thgr; from said inlet end, X, Y, and Z have an origin at the center of said inlet end, and the z-axis is perpendicular to said first plane.
