Connection structure for a generator assembly

A propulsion engine, comprising:

• a shaft;
• an electrical system comprising:
• a generator assembly disposed in the propulsion engine, the generator assembly coupled to the shaft;
• and
• a plurality of electrical connector lines extending from the generator assembly;
• a cooling system comprising a first cooling duct in fluid communication with a coolant source, wherein at least one of the plurality of electrical connector lines extends through the first cooling duct such that the at least one of the plurality of electrical connector lines is cooled via coolant from the coolant source;
• a first support bracket located in the first cooling duct, the support bracket comprising a body having a plurality of openings through which the plurality of electrical connector lines extends;
• a second cooling duct in fluid communication with the first cooling duct, the second cooling duct having a different cross-sectional area than the first cooling duct, wherein the plurality of electrical connector lines extends through both the first cooling duct and the second cooling duct;
• and
• a second support bracket supporting the plurality of electrical connector lines within the second cooling duct, wherein the second support bracket has a different structure than the first support bracket.

A propulsion engine, comprising:

• a shaft;
• an electrical system comprising:
• a generator assembly disposed in the propulsion engine, the generator assembly coupled to the shaft;
• and
• an electrical connector line extending from the generator assembly;
• a cooling system comprising a first cooling duct in fluid communication with a coolant source, wherein the electrical connector line extends through the first cooling duct such that the electrical connector is cooled via coolant from the coolant source;
• and
• a first plurality of support structures supporting the electrical connector line at a plurality of discrete locations within the first cooling duct, wherein each of the first plurality of support structures contacts an internal surface of the first cooling duct at a plurality of points such that the electrical connector line does not directly contact an internal surface of the first cooling duct,
• wherein at least one of the first plurality of support structures comprises a support bracket comprising a body through which the electrical connector line extends,
• wherein the electrical connector line is one of a plurality of electrical connector lines that extend through the body of the support bracket,
• wherein the body of the support bracket comprises a plurality of openings, where each of the plurality of electrical connector lines extends through a respective one of the plurality of openings,
• wherein the body of the support bracket comprises a central opening that is configured to allow coolant to flow through a central region of the support bracket.
