Abstract
A liner assembly for a gas turbine engine includes a liner defining an inner surface exposed to exhaust gases and a duct spaced radially outward of the liner. A hanger assembly supports the liner relative to the duct. The hanger assembly includes a body segment attached to the liner and first and second washers defining a gap therebetween that receives a portion of the body segment. The gap between the washers and the body segment provides for relative movement caused by differences in thermal growth within the liner. An attachment member extending between the body section and the duct includes spherical ends that are seated on the first and second washers to accommodate misalignments during assembly.
Claims8
A liner assembly for a gas turbine engine comprising:
- a liner defining an inner surface exposed to exhaust gases from the gas turbine engine;
- a duct spaced radially outward of the liner;
- and
- a hanger assembly supporting the liner relative to the duct, the hanger assembly including a body segment attached to the liner, a first washer disposed within an opening of the body segment, and a second washer disposed within the opening of the body segment, a portion of the first washer in abutting contact with a portion of the second washer within the opening of the body segment, the first washer and the second washer defining a gap therebetween, wherein the gap between the first washer and the second washer receives a portion of the body segment such that the body segment is movable relative to the first washer and the second washer, and an attachment member is seated on the first washer and the second washer and attached to the duct.
