Turbine exhaust duct with stiffeners for aircraft engines

Abstract

A turbine exhaust duct (TED) for an aircraft engine, has: a body having a central axis and having an inner wall and an outer wall conjointly defining an annular inlet conduit and outlet conduits communicating with the annular inlet conduit and extending generally radially outward relative to the annular inlet conduit along conduit axes extending transversally to the central axis, the body defining a central passage located radially inwardly of the annular inlet conduit, the outlet conduits having transition areas transitioning from a mainly axial direction to a mainly radial direction; and stiffeners secured to the body and located within the central passage at circumferential positions being in register with the outlet conduits, the stiffeners secured to the transition areas of the outlet conduits, the stiffener extending transversally to both of the central axis and the conduit axes.
