Abstract
An annular shroud assembly for a gas turbine engine is provided. The annular shroud assembly includes a plurality of first shroud segments having a same first arcuate length within a tolerance, at least one second shroud segment having a second arcuate length different than the first arcuate length and outside the tolerance, a plurality of first intersegment gaps between adjacent first segments, the first intersegment gaps having a circumferential dimension within a desired controlled range of dimensions, and at least two second intersegment gaps between opposed ends of the second segment and adjacent first segment. The first and second intersegment gaps are within the desired controlled range. Methods for controlling intersegment gaps between a plurality of shroud segments forming an annular shroud assembly and for forming such annular shroud assembly are also provided.
