Abstract

A compressor assembly (300) includes a compressor (144) including a central shaft (210) including an external surface (214), a shroud (220) extending circumferentially around the central shaft. The shroud including a radially inward surface (224) and radially outward surface (222) located opposite the radially inward surface. The external surface of the central shaft and the radially inward surface of the shroud are in a facing spaced relationship forming a core flow path (C) therebetween. The compressor also includes a plurality of blades (125) extending from the central shaft to the shroud. The compressor assembly also includes a compression ring (400) extending circumferentially around the shroud, the compression ring being in an interference fit with the shroud. The compression ring is configured to apply a radially inward compressive force (F1) along one or more portions of the radially outward surface of the shroud, the radially inward compressive is configured to compress the shroud and the plurality of blades into the central shaft.
