Combustor transition

A combustor transition adapted to guide combustion gases in a hot gas flow path extending between a gas turbine combustion chamber and a first stage of a turbine, the combustor transition comprising:

• a duct having an inlet at an upstream end adapted for connection to the combustion chamber and an outlet at a downstream end adapted for connection to the first stage of the turbine, wherein the downstream end comprises an outer wall, an inner wall, a first side wall and a second side wall, wherein at least one side wall has a side wall extension which extends in a downstream direction beyond the outlet and wherein the side wall extension at least partly encloses a first resonator volume or wherein the first and second side wall extensions of two combustor transitions are configured such that the first and second side wall extensions, when installed next to each other in a gas turbine, at least partly encloses a first resonator volume, and wherein at least one side wall extension comprises a resonator hole, which is configured as a neck of a Helmholtz-damper.
