Abstract
A shrouded blade for insertion into an axial disk slot and having a radial spacer and a circumferential groove is provided with a segmented retainer bar which fits into the circumferential groove to axially retain the blade. The retainer bar includes flanges which extend radially inward on either side of the spacer such that the spacer provides positive placement for the retainer bar in both the radial and circumferential directions.
