Electrified urban air mobility vehicles require advances in the specific power, efficiency, and reliability of electric motor drivetrains. Gearing an electrified aircraft’s drivetrain generally leads to a lighter weight and/or more efficient drivet

This paper describes the development of thermal management systems (TMS) for three electrified aircraft propulsion (EAP) vehicle concepts released by NASA that span the UAM, regional, and single-aisle markets. For each EAP concept, a conventional TMS

Managing trajectory separation of unmanned aircraft is critical to ensuring accessibility, efficiency, and safety in low altitude airspace. The concept of a geo-fence has emerged as a way to manage trajectory separation. A geo-fence consists of dista
