Claim Text:
1. An apparatus for supporting an aft portion of a transition duct in a gas turbine engine, comprising: an annular shaped stator component disposed in a turbine section of the gas turbine engine, a transition aft frame that engages with the stator component, the transition aft frame comprising a radially outer panel, a radially inner panel, and circumferentially spaced first and second side panels connecting the radially inner and radially outer panels, wherein a forward face of the stator component comprises a first connection point and a second connection point spaced apart in a circumferential direction, each of the connection points comprising a respective slot, wherein the transition aft frame comprises first and second attachment structures that respectively engage with the first and second connection points on the forward face of the stator component when the transition duct is aligned axially with the stator component, the first and second attachment structures being spaced apart, the spacing being effective to transfer moment load from the first and second attachment structures to the first and second side panels respectively, wherein each of the attachment structures comprises a link that is rotatable about a tangential axis, and wherein an aft end of the link comprises a tangential pin that is engageable with a corresponding one of said slots on the forward face of the stator component, the link being rotatable about the center of the pin upon engagement of the pin in the slot.
