Turbine exhaust case with stiffening brace

A reverse-flow gas turbine engine, comprising:

• an outer case assembly extending around a central axis and enclosing a core, the core including a compressor section, a combustor, and a turbine sectioned, the turbine section located forward of the combustor and of the compressor section relative to a direction of travel of the reverse-flow gas turbine engine, the outer case assembly including an exhaust case extending around the central axis and axially between a forward end and a rearward end, the exhaust case defining openings between the forward end and the rearward end;
• exhaust ports secured to the exhaust case and being in register with the openings, the exhaust ports protruding away from the exhaust case in a direction having a radial component relative to the central axis, the exhaust ports extending circumferentially around port axes being transverse to the central axis;
• a turbine exhaust duct (TED) having an annular inlet conduit extending around the central axis for directing combustion gases in an axial direction, and outlet conduits fluidly communicating with the annular inlet conduit and extending generally radially outwardly relative to the annular inlet conduit, the outlet conduits communicating with the openings of the exhaust case and with the exhaust ports;
• and
• stiffening braces secured to the exhaust ports at opposite locations on the exhaust ports, the stiffening braces extending across the exhaust ports transversally to the port axes.
