Abstract:
1. A method of coupling a first portion of a gas turbine transition duct to a second portion of a gas turbine transition duct to reduce vibratory deflection comprising: coupling at least one first support structure to said gas turbine transition duct first portion; coupling at least one second support structure to said gas turbine transition duct second portion; and coupling said at least one first support structure to said at least one second support structure by creating at least one sliding joint between said at least one first support structure and said at least one second support structure such that a substantial amount of thermal expansion induced sliding movement is permitted between said at least one first support structure and said at least one second support structure while a substantial amount of vibration induced sliding movement is prevented, wherein said at least one sliding joint permits a first linear sliding movement in a first direction substantially perpendicular to a section of said gas turbine transition duct second portion to which said at least one second support structure is coupled and a second greater linear sliding movement in a second direction substantially parallel to said section of said gas turbine transition duct second portion, said second direction being substantially perpendicular to a longitudinal axis of said one second support structure.
