Claim:
1. A radial diffuser exhaust system for use with a gas turbine engine, comprising: a radial diffuser comprising a longitudinal axis, an inner diffuser guide positioned about the longitudinal axis, an outer diffuser guide positioned about the longitudinal axis, and a plurality of support struts positioned between the inner diffuser guide and the outer diffuser guide; the outer diffuser guide comprising an upstream portion having a conical shape and expanding in a downstream direction and a downstream portion having a conical shape and expanding in the downstream direction, wherein the upstream portion comprises an upstream acute expansion angle relative to the longitudinal axis of the radial diffuser, wherein the downstream portion comprises a downstream acute expansion angle relative to the longitudinal axis of the radial diffuser, wherein the upstream acute expansion angle is larger than the downstream acute expansion angle, wherein the upstream portion and the downstream portion are adjacent one another, and wherein an interface between the upstream portion and the downstream portion is positioned at leading edges of the plurality of support struts; and an exhaust collector positioned asymmetrically about the radial diffuser.
