Abstract
A retainer for a gas turbine engine includes a center body, a plurality of struts, and a ring. The plurality of struts are connected to and extend outward from the center body. The ring is connected to the plurality of struts and is positioned aft of the center body with respect to a direction of airflow through the gas turbine engine.
Claims18
A retainer for a gas turbine engine comprising:
- a center body;
- a plurality of struts connected to and extending outward from the center body in a downstream direction such that each strut forms an acute angle with a centerline axis of the gas turbine engine;
- and
- a ring connected to the plurality of struts, wherein the ring is positioned aft of the center body with respect to a direction of airflow through the gas turbine engine, wherein the ring is connected to and forms a portion of an exhaust housing of the gas turbine engine.

A gas turbine engine comprising:
- a turbine hub;
- and
- a generally conically shaped retainer positioned axially aft of and spaced at a distance from the turbine hub, wherein the retainer comprises:
- a center body;
- a plurality of struts connected to and extending axially downstream and radially outward from the center body such that each strut forms an acute angle with a centerline axis of the gas turbine engine, wherein each of the plurality of struts has a radially inner end joined to the center body and a radially outer end that is downstream from the radially inner end;
- and
- a ring connected to the plurality of struts at the radially outer ends thereof.

A generally conically shaped retainer for a gas turbine engine, comprising:
- a center body;
- a plurality of struts shaped as rods, each with a circular cross-section and connected to and extending outward in a downstream direction from the center body such that each strut forms an acute angle with respect to a centerline axis of the gas turbine engine;
- and
- a ring connected to the struts at outer radial ends thereof, wherein the ring is positioned aft of the center body with respect to a direction of airflow through the gas turbine engine, and wherein the ring is connected to and forms a portion of an exhaust housing of the gas turbine engine.
