Abstract
A method enables a gas turbine engine including a first rotor assembly and a second rotor assembly coupled in axial flow communication downstream from the first rotor assembly to be assembled. The method comprises coupling an upstream end of an extension duct to an outlet of the first rotor assembly, wherein the extension duct includes a plurality of panels coupled circumferentially, and coupling a downstream end of the extension duct to an inlet of the second rotor assembly using at least one fish mouth seal.

A method for assembling a gas turbine engine including a first rotor assembly and a second rotor assembly coupled in axial flow communication downstream from the first rotor assembly, said method comprising:
- coupling an upstream end of an extension duct to an outlet of the first rotor assembly, wherein the extension duct includes a plurality of panels coupled circumferentially;
- and
- coupling a downstream end of the extension duct to an inlet of the second rotor assembly using at least one fish mouth seal.
An annular turbine frame for a gas turbine engine, said turbine frame comprising a plurality of panels coupled together to form an extension duct, said extension duct comprising a radially outer panel portion and a radially inner panel portion, at least one of said radially outer panel portion and said radially inner panel portion is coupled within the gas turbine engine by at least one fish mouth seal.
A gas turbine engine comprising:
- a first rotor assembly;
- a second rotor assembly downstream from said first rotor assembly, said second rotor assembly axially coupled in a flow communication with said first rotor assembly,
- an extension duct extending from an outlet of said first rotor assembly to an inlet of said second rotor assembly, said extension duct comprising an upstream end, a downstream end, and a plurality of panels coupled circumferentially therebetween, at least one of said extension duct upstream end and said extension duct downstream end coupled to said turbine engine by at least one fish mouth seal.
