Claim 8:
9. A turbine module comprising:
a turbine rotor, wherein the turbine rotor comprises:
a base;
a plurality of blades circumferentially spaced about an axis of rotation and extending from the base, each of the plurality of blades extending radially outward from the base to a tip and chordwise from a leading edge to a trailing edge, and each of the plurality of blades having a suction side and a pressure side, wherein the base and each of the plurality of blades curve such that radially outward portions of the base and the plurality of blades extend more in a radial direction than in an axial direction, and wherein radially central portions of the base and the plurality of blades extend similarly in the radial direction and the axial direction;
a central nose radially inward of the plurality of blades, wherein the central nose defines the axis of rotation;
a plurality of cooling manifolds disposed within the turbine rotor; and
a plurality of exit jets extending from the plurality of cooling manifolds and extending through the trailing edge of each blade of the plurality of blades;

a housing partially surrounding the turbine rotor;
a shaft mounted within the housing, the shaft comprising:
a seal between a bearing and a rear surface of the turbine rotor; and
a cooling gap defined by the housing and the rear surface of the turbine rotor.
