Combustion chamber assembly having a transition duct damping member

A combustion chamber assembly comprising a plurality of circumferentially spaced combustion chambers, a plurality of circumferentially spaced transition ducts, at least one damping member and at least one fastening assembly, each combustion chamber comprising at least one combustion zone defined by at least one peripheral wall, each transition duct being arranged at the downstream end of a corresponding one of the combustion chambers to receive the exhaust gases from the corresponding one of the combustion chambers, at least one of the transition ducts being connected to the at least one damping member, the at least one transition duct being connected to the at least one damping member by the at least one fastening assembly, each fastening assembly comprising means to resiliently bias the at least one damping member into contact with the at least one transition duct to provide frictional damping of any vibrations of the at least one transition duct.
