Abstract
A compressor has a plurality of stages, and each of the stages includes a wheel. Each wheel is configured to receive one or more rotor blades. The compressor includes a patch ring mounted on a first rotor wheel. The first rotor wheel has a first rabbet machined therein, and the patch ring is located on the first rabbet. A second rotor wheel is located upstream from the first rotor wheel. The second rotor wheel has a second rabbet machined therein, and the second rabbet is configured to be located opposite to the first rabbet. The second rabbet has a second fillet located between axial and radial surfaces of the second rabbet. The patch ring has a radial height greater than or equal to a radial height of the second fillet.
