Claims16
A hanger assembly for a gas turbine engine comprising:
- a flexible leaf spring having a body and a pair of legs spaced apart by said body,
- a locking member attaching said pair of legs to a first duct of the gas turbine engine, said locking member including a cover and a pair of retention members spaced apart by said cover, each of said pair of retention members configured to capture one leg of said pair of legs, and
- a mounting member attaching said body to a second duct of the gas turbine engine,
- wherein each of said retention members includes a first flange formed upon said cover and extending from said cover towards said body, and a second flange extending from said first flange at an outer obtuse angle, wherein said first flange and said second flange capture one leg of said pair of legs.

- a fan section including a plurality of fan blades rotatable about an axis;
- a compressor section in communication with the fan section;
- a combustor in fluid communication with the compressor section;
- a turbine section in fluid communication with the combustor and driving the fan section and the compressor section;
- and
- an exhaust liner assembly aft of the turbine section, the exhaust liner assembly including a liner defining an inner surface exposed to exhaust gases, and a duct spaced radially outward of the liner;
- and
- a hanger assembly supporting the liner relative to the duct, the hanger assembly including a flexible leaf spring having a body and a leg, a locking member attaching said leg to said duct;
- and a mounting member attaching said body to said liner;
- and
- wherein said locking member includes a cover disposed outside of said duct, a first flange formed upon said cover and extending from said cover towards said body and a second flange extending from said first flange at an outer obtuse angle, wherein said first flange and said second flange capture said leg.
