At least one secondary flow duct having one opening each is provided in the main flow path boundary 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. The structural assembly has at least one support component and at least one insertion component. The support component includes a recess extending in the circumferential direction that receives the at least one insertion component such that the support component surrounds the at least one insertion component largely on its sides not facing the main flow path, and where the insertion component completely surrounds or forms at least one secondary flow duct.

摘要： A structural assembly for a fluid-flow machine includes a main flow path boundary, a row of relatively rotating blades with a gap existing between the blade ends and the main flow path boundary. A secondary flow duct is connected to the main flow path via the two openings spaced apart in the flow direction. A structural assembly has at least one support component and at least one replaceable plug connected directly or indirectly to the support component. The replaceable plug includes a part-section of a secondary flow duct, where the part-section complements at least one further part-section of the secondary flow duct extending outside the plug in the structural assembly to form a secondary flow duct which is continuous between its openings.

摘要： A cover band assembly of a blade row of stator or rotor blades is provided. The cover band assembly comprises a blade row that is arranged inside a main flow path of a continuous-flow machine and has multiple blades which respectively have a front edge and a rear edge; and a cover band of the blade row that is at least partially embedded in a component or a component group as regarded in a longitudinal section of the continuous-flow machine, wherein a cavity is formed that surrounds the cover band and is connected to the main flow path by way of two cavity openings, wherein the front cavity opening is provided upstream of the front edge and the rear cavity opening is provided downstream of the rear edge of the blades of the blade row. Here, the cover band has a leading edge and a trailing edge.

摘要： A blade row group arrangeable in a main flow path of a fluid-flow machine and including N adjacent member blade rows firmly arranged relative to one another in both the axial direction and the circumferential direction is provided. Here, a front member blade row with front blades as well as a rear member blade row with rear blades are provided in the meridional plane established by the axial direction and the radial direction. The blade row group has two main flow path boundaries. It is provided that the blades of the member blade rows are fixed to the one main flow path boundary in the surrounding structure by means of a blade root structure, and that the blades of the member blade rows on the other main flow path boundary are each firmly connected to a base.
