Abstract
A stator attachment system couples a stator to a compressor case that is split to define a first half and a second half. The stator attachment system includes a plurality of retention slots defined in each of the first half and the second half of the compressor case. The plurality of retention slots is spaced apart about a perimeter of the first half and the second half such that at least one of the plurality of retention slots associated with the first half is vertically aligned with at least one of the plurality of retention slots associated with the second half. The stator attachment system includes a plurality of tabs defined on the stator that extend radially outward from the stator. Each of the plurality of tabs is configured to engage with one of the plurality of retention slots to couple the stator to the compressor case.
