1. A main stage generator rotor comprising:
a winding-pole set comprising a winding and a pole; and
a winding retention member;
wherein the main stage generator rotor has an axis of rotation,
wherein the axis of rotation has a radius,
wherein the winding retention member is disposed outboard of the winding-pole set along the axis of rotation,
whereby the winding of the winding-pole set is axially confined between the winding retention member and the pole of the winding-pole set, and
whereby the winding of the winding-pole set is constrained by the winding retention member from radially translating,
the winding retention member comprising:
an axial containment plate disposed outward of the axis of rotation with respect to the winding of the winding-pole set and constraining the winding from radially translating;
a tensioning apparatus whereby the axial containment plate is retained in position relative to the winding-pole set;
a first axially facing surface;
a second axially facing surface opposite the winding retention member from the first axially facing surface;
a cooling oil routing hole extending axially from the first axially facing surface, through the winding retention member, to the second axially facing surface, whereby cooling oil may travel axially through the axial containment plate, and
an oil flow path disposed between a rotor inlet orifice and the cooling oil routing hole whereby oil may flow in fluidic communication with the winding,
wherein the cooling oil routing hole is axially in-line with the winding.
