ABSTRACT OF THE DISCLOSURE This invention describes a double wall step- liner construction for a combustion chamber of a combus- tion turbine. The chamber is a series of concentric cylindrical segments stacked in overlapping arrangement such that the leading edge of each outer segment and the terminal edge of each inner segment are in general axial alignment so as to form a continuous double wall through- out the axial length of the step-liner configuration. Each cylindrical segment is attached at its inlet end and at its outlet end to the adjacent cylindrical segment by an annular transition member formed of a wire mesh secured to each respective cylindrical segment with high tempera- ture brazing. The relative thermal expansion between the inner and outer cylindrical segments (both axially and radially) is accommodated by deflection and distortion of the wire mesh transition members which also permits cool- ing air to enter between the overlapping segments and to be discharged therefrom into the combustion chamber with minimum interference.
