<p>A composite annular shroud (42) supported by a support assembly (46) including at least two single piece full 360 degree rings (50, 52, 54 or 130) and at least partially disposed within an innermost one of the rings. The shroud (42) is biased against and in sealing engagement with an inner flange (84) of the innermost ring. A three ring assembly includes the inner ring (50) disposed radially inwardly of a middle ring (52) disposed radially inwardly of an outer ring (54) and the shroud (42) at least partially disposed within the inner ring (50). At least three clocking pins (74) extend radially inwardly from the middle ring (52) through slots (76) in the inner ring (50) into notches (78) in the shroud (42). The middle ring (52) may be an aft end (70) of a support ring (68) fixedly connected to an engine backbone (58). Mounting pins (104) may be press fitted into pin holes (106) in the middle ring (52) and extend radially outwardly from the middle ring (52) through radial holes (107) in the outer ring (54).</p> |
