Advanced aero diffusers for turbine frames and outlet guide vanes

A turbine engine comprising:

• a plurality of struts arranged radially between an inner portion and an outer portion of the turbine engine;
• and
• a plurality of flowpath surfaces supported by the plurality of struts, the plurality of flowpath surfaces extending radially between the inner portion and the outer portion of the turbine engine along a circumference of the inner portion and the outer portion of the turbine engine to control diffusion of air flow in an axial direction,
• wherein the plurality of flowpath surfaces includes a first flowpath surface and a second flowpath surface, the first flowpath surface parallel to the second flowpath surface at a first end and diverging away from each other at an angle at a second end.
