Abstract
An exemplary turbine engine link assembly includes a link extending longitudinally from a rod end and terminating at a hemispherical end. The rod end is secured to an engine liner or an engine casing. The hemispherical end is biased toward a corresponding hemispherical recess in the engine liner or in the other of the engine liner or the engine casing.
Claims19
A turbine engine assembly comprising:
- a first attachment structure secured directly to an engine liner;
- a second attachment structure secured directly to an engine casing, wherein the engine liner and the engine casing together establish a bypass flowpath of a turbine engine;
- a link having a rod portion extending longitudinally from a hemispherical end portion and terminating at a rod end portion, the hemispherical end portion received within a recess defined by the first attachment structure, the rod end portion secured relative to the second attachment structure;
- and
- a spring biasing the hemispherical end portion toward the recess defined by the first attachment structure, the hemispherical end portion extending away from the rod portion and terminating at a leading surface that does not extend past a perimeter of the hemispherical end portion, wherein the spring contacts the leading surface of the hemispherical end portion and the spring is housed within the first attachment structure.

A turbine engine link assembly, comprising:
- a link extending longitudinally from a rod end and terminating at a hemispherical end, the rod end secured to one of an engine liner or an engine casing, the hemispherical end biased by a spring toward a corresponding hemispherical recess provided by the other of the engine liner or the engine casing, wherein the link extends across a bypass flow path of a gas turbine engine and is positioned radially between an engine casing and an engine liner.
A turbine engine assembly, comprising:
- a first attachment structure of an engine liner;
- a second attachment structure of an engine casing, the engine liner and the engine casing together establishing a bypass flowpath of a turbine engine;
- a link radially bounded by the engine liner and the engine casing, the link having a rod portion extending longitudinally from a hemispherical end portion and terminating at a rod end portion, the hemispherical end portion received within a hemispherical recess defined by the first attachment structure, the rod end portion secured relative to the second attachment structure;
- and a spring biasing the hemispherical end portion of the link toward the hemispherical recess defined by the first attachment structure.
