    Abstract: A starter/generator arrangement includes a starter/generator, a power converter electrically connected to the starter/generator, and coolant circuit with a pump and a condenser in fluid communication with the power converter. The power converter is arranged to flow start mode electrical power in a first direction in a start mode and a second direction in a generate mode. The coolant circuit fluidly couples the pump to the condenser for storing heat in a coolant disposed within the coolant circuit while flowing the start mode electrical power in the first direction. Gas turbine engines and methods of cooling starter/generator arrangements are also described.

    Abstract: A power distribution system includes an electrical contactor arrangement. The electrical contactor arrangement includes a first contactor post, a first contactor lead, and a second contactor lead. The first contactor post extends from a first bus bar. The first contactor lead extends from the first contactor post. The first contactor lead is at least partially received within a contactor housing. The second contactor lead is spaced apart from the first contactor lead and extends from the first contactor post. The second contactor lead is at least partially received within the contactor housing.

    Abstract: A cooled compressor system is provided including: a compressor that in operation compresses air; an electric motor that in operation drives the compressor, the electric motor having a back iron, a motor stator radially inward from the back iron, and a motor rotor radially inward from the motor stator; an airflow system fluidly connected to the compressor, the airflow system in operation directs air through the back iron and in between the motor stator and motor rotor; an airflow inlet that in operation allows an inflow of air to the airflow system; and an airflow outlet that in operation allows an outflow of air from the airflow system; wherein the air travels from the airflow inlet to the airflow outlet through the compressor and the airflow system.
