A transition duct support apparatus and a method to support an exit frame in a transition duct in a gas turbine engine are provided. A stiffener () may be arranged to provide support to an outer edge () of an exit frame () in a transition duct (). Stiffener () may be configured to circumferentially extend between mutually opposed corners () of the exit frame of the transition duct. A brace () may be connected to a centrally-disposed section () and may extend to support respective end portions () of the stiffener. The support apparatus is effective to provide a respective tuned level of stiffness support with respect to one or more axes of the exit frame in the transition duct. The apparatus and method may be effective for distributing mechanical stresses on the exit frame of the transition duct and/or neighboring regions in the transition duct.

Transition duct support and method to provide a tuned level of support stiffness

A gas engine turbine has a transition duct () that has improved cooling features and a method for forming the cooling features. A continuous exit section cooling channel () is formed through the transition duct panel (), the exit frame () and the connection (). The continuous exit section cooling channel () reduces the need for effusion channels in the transition duct. The continuous exit section cooling channel () further reduces costs and improves the emissions associated with the transition duct () of the gas engine turbine.
