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 carried only to three decimal places wherein the coordinates are taken at a sweep angle θ wherein θ is an angle measured from said inlet end and X, Y, and Z are coordinates defining the panel assembly profile at each angle θ from the inlet end. An alternate embodiment is also disclosed defining an envelope for the uncoated internal profile of the panel assembly.
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 θ, 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 θ 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 θ is measured, and X, Y, and Z are coordinates defining the panel assembly profile at each angle θ 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.
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 within an envelope of +/−0.250 inches in a direction normal to any surface with coordinate values X, Y, and Z at an angle θ, 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 θ 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 θ is measured, and X, Y, and Z are coordinates defining the panel assembly profile at each angle θ 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.
