Abstract
The present invention relates to a subassembly for a gas turbine, in particular a gas turbine aircraft engine, having a turbine casing (); a midframe (), which is adjacent downstream to the turbine casing and has a number of support ribs () spaced apart in the peripheral direction. The turbine casing and the midframe define a flow duct () for a working gas exiting a combustion chamber of the gas turbine, and a cavity, in particular a cooling air duct (), with an opening on the flow duct side is formed between the turbine casing and the midframe. An edge contour () of the opening on the turbine casing side varies along the periphery radially and/or axially.
