Abstract

See full text

A shroud arrangement for a fluid-flow machine includes a blade root connected to at least one blade/vane end of a row of rotor blades or stator vanes, or is connected to at least one such blade/vane end. A shroud is connected to the blade root on the side of the blade root facing away from the blades/vanes. The blade root on the side facing away from the blades/vanes has two blade root fingers extending substantially in the radial direction and axially spaced from one another, the blade root fingers forming between them a recess being continuous in the circumferential direction. An element or area of the shroud for fastening to the blade root is arranged in the recess. The shroud has two webs extending into the recess and enclosed by the blade root fingers, with the two webs forming substantially a V-shaped arrangement.
