1. A rotor housing for an aircraft rotary engine, the rotor housing comprising:
a side housing body extending along an axis between and to an inner axial housing side and an outer axial housing side, the side housing body forming a fluid cooling passage and a plurality of ribs, the fluid cooling passage extending about the axis at the inner axial housing side, the plurality of ribs coincident with and extending into the fluid cooling passage, the plurality of ribs distributed about the fluid cooling passage as an array of ribs;
a rail disposed at the plurality of ribs, the rail extending axially between and to the plurality of fluid cooling channels and the inner axial housing side, the rail extending about the fluid cooling passage; and
a side plate including an inner axial plate side, an outer axial plate side, and a perimeter edge, the perimeter edge disposed at the rail;
the side housing body and the rail forming a plurality of fluid cooling channels connected in fluid communication with the fluid cooling passage, the outer axial plate side further forming the fluid cooling passage at the plurality of fluid cooling channels.
