1. A propulsion engine, comprising:
a core portion generating exhaust that travels in an axial direction;
a turbine section coupled to a shaft, wherein the turbine section receives the exhaust and generates mechanical energy to rotate the shaft;
a turbine frame attached to the turbine section, the turbine frame comprising:
an outer casing coupled to the turbine section;
an inner hub supporting the shaft via a bearing assembly; and
a plurality of struts extending between the outer casing and the inner hub, wherein at least one strut of the plurality of struts defines an internal cavity having a cooling duct disposed therein; and
an electrical system comprising:
a generator assembly coupled to the shaft and to the inner hub via a generator coupler; and
an electrical connector line extending through the cooling duct and the generator coupler to an electrical coupler electrically coupled to the generator assembly, wherein the generator assembly comprises a manifold that includes a coolant opening to receive coolant from the cooling duct via the generator coupler, the manifold forming a radial wall that extends radially past the electrical coupler and the coolant opening is provided through the radial wall.
