Suspension for an annular gas turbine combustor
Abstract
The invention relates to a suspension of an annular gas turbine combustion chamber in the outlet region thereof on a housing wall, via an adjoining the outer combustion chamber wall, annular, kinked arm structure having an outer and an inner leg with respect to the gas turbine longitudinal axis. According to the invention, a flange connects to the outer leg, which is connected via a releasable connecting element fixed to the housing wall. Preferably, both legs over the circumference of uniformly distributed, dovetailed openings on whose narrowest portions of the bending line of the arm structure facing and open to the bending line, so that there is a connection gap between each opening in the outer leg and the adjacent opening in the inner leg.
