Abstract: A shroud hanger assembly or shroud assembly is provided for dimensionally incompatible components wherein the assembly includes a multi-piece hanger, for example having a forward hanger portion and a rearward hanger portion. A cavity is formed between the parts; wherein a shroud may be positioned which is formed of a low coefficient of thermal expansion material. The hanger and shroud may be formed of the same material or differing materials in order to better match the thermal growth between the hanger and the shroud. When the shroud is positioned within the hanger opening or cavity, one of the forward and rearward hanger portions may be press fit or otherwise connected into the other of the forward and rearward hanger portion.

Abstract: A composite duct panel assembly is provided. The composite duct panel assembly includes a composite duct panel having a curved cross-section in a circumferential direction and a width based on the panel including a portion of a circumference of an annular bypass duct. In one embodiment, at least two adjacent corners of the panel are greater than 90°. In one embodiment, the panel includes a circumferential flange along a circumferential edge and an axial flange along an axial edge, and the assembly further includes a corner bracket coupled to the panel, the circumferential flange, and the axial flange. The corner bracket includes a flange corner having an approximate 90° angle, the flange corner extending the axial flange and the circumferential flange to an intersection at a corner of the panel.
