Abstract: Various implementations directed to a ground support equipment unit for use with electric aircraft are provided. In one implementation, a ground support equipment (GSE) unit may include a GSE thermal loop coupled to one or more channels of a battery pack onboard an aircraft, where the GSE thermal loop is configured to allow fluid from the one or more channels to circulate therein. The GSE unit may also include a GSE thermal system coupled to the GSE thermal loop, where the GSE thermal system is configured to regulate a battery temperature of the battery pack.

Abstract: One embodiment is an electric drive system for an aircraft including a motor, a gear box associated with the motor, and a cooling fan for drawing air into the unit across an electronic component to cool the electronic component and for expelling air into an oil cooler for cooling oil contained therein. The electric drive system further includes an oil distribution system for distributing oil cooled by the oil cooler to at least one motor and at least one gearbox, the distributed oil being used to cool the motor and the gearbox, a reservoir for collecting the distributed oil after it has been used to cool the motor and the gearbox, and at least one structural element for retaining the motor, gearbox, the cooling fan, the oil distribution system, and the reservoir together as a unit.
