摘要： Apparatus and method embodying slide on shroud cover segments for gas turbine compressor stator vanes are provided. The apparatus may include a first shroud cover segment (12) including a respective circumferential groove (14). A gas turbine compressor stator vane (10) has a respective base anchoring joint (16) configured for slide on insertion in the respective circumferential groove (14). A stop (18) at a first end (20) of the respective circumferential groove (14). The first end of the respective circumferential groove located opposite a second end (22) of the respective circumferential groove, the second end of the respective circumferential groove may be an open end. A group of gas turbine compressor stator vanes (10a) may be disposed between the stop and the open end of the first shroud cover segment. Disclosed embodiments in a cost-effective and reliable manner, eliminate the need for any bolted or welded assemblies, which is conducive to user-friendly and efficient replacement of individual stator vanes during servicing.

摘要： The invention relates to a rotor (1) for a turbomachine (2) having an annular flow path (3) as seen in cross section, com-prising at least two shaft collars (5, 6) that are arranged axially adjacently and at a predetermined spacing, forming an annular intermediate space (7), said shaft collars (5, 6) each having around their circumference a multiplicity of holding grooves (8) which extend at least in part axially and continuously and into which blade roots (9, 10) of radially outwardly extending rotor blades (11, 12) have been introduced, characterized in that two ring elements (19, 20) that are arranged axially adjacently are provided in the annular intermediate space (7) present between the two shaft collars (5, 6), said ring elements (19, 20) each being composed of a plurality of ring element segments (19a, b, c, etc., 20a, b, c, etc.) and the radial outer faces (21, 27) of said ring elements (19, 20) bounding the flow path (3), in that the first ring element (19) bears at least regionally in a form-fitting manner against the adjacent first shaft collar (5) and against the second ring element (20) and the second ring element (20) bears at least regionally in a form-fitting manner against the first ring element (19) and against the adjacent second shaft collar (6), and in that the ring elements (19, 20) are able to be fitted and removed without the two shaft collars (5, 6) being moved relative to one another.
