1. Structural assembly for a fluid-flow machine provided with:
a main flow path boundary confining a main flow path of a fluid-flow machine, where at least one row of blades each with one blade end is arranged in the main flow path, where a gap exists between the blade ends of the at least one row of blades and the main flow path boundary, and where there is a rotating relative movement between the blades of a blade row and the main flow path boundary, and at least one secondary flow duct, having in the main flow path boundary one opening each at ends spaced apart in the flow direction, such that the secondary flow duct is connected to the main flow path via the two openings,whereinthe structural assembly has at least two components connected to one another, i.e. at least one support component and at least one connecting component, where the support component at least partially forms the main flow path boundary and where the connecting component forms or surrounds at least one part-section of the secondary flow duct. |
