Abstract: A hybrid drive system can include a shaft, an electrical machine comprising a rotor and a stator, and a mechanical disconnect system connecting the rotor to the shaft. The mechanical disconnect system is configured to mechanically connect the rotor to the shaft in a first state and to mechanically disconnect the rotor from the shaft in a second state such that rotor does not drive the shaft or such that the rotor is not driven by the shaft. The rotor can be a permanent magnet rotor, for example.

Abstract: A cooling system includes a thermal engine having a fluid output, and a motor drive having a fluid inlet in fluid communication with the fluid output of the thermal engine. The fluid inlet of the motor drive is downstream from the fluid output of the thermal engine. The system includes a fluid storage downstream from the motor drive and a fluid output of the motor drive. A method of cooling a motor drive includes outputting a cooling fluid from a fluid output of a thermal engine, receiving the cooling fluid from the fluid output of the thermal engine in a fluid inlet of a motor drive, passing the cooling fluid through the motor drive to a fluid output of the motor drive, receiving the cooling fluid in a fluid storage.

Abstract: An aircraft hybrid electrical system includes an electric power generating system in signal communication with a thermal combustion engine, a secondary power system in signal communication with the electric power generating system, and a battery in signal communication with the electric power generating system and the secondary power system. The aircraft hybrid electrical system further comprises a system controller in signal communication with the electric power generating system, secondary power system, and the battery. The system controller is configured to monitor a charge capacity of the battery and selectively operate in a current charge mode and a voltage charge mode to charge the battery. The system controller invokes the current charge mode in response to detecting the charge capacity falls below a charge capacity threshold, and invokes the voltage charge mode in response to detecting the charge capacity reaches a target value.
