Abstract: This invention relates to electrically-driven propulsors for regional aircraft. These combine fans optimized for quiet regional operations with rotating variable pitch mechanisms contained within the hubs and highly efficient ring electric motors. The ring motors are used to drive annular fans at the inner or outer radius, or a conventional fan at the inner radius. The assembly combines a single fan, fixed or variable pitch, with a row of stators, or multiple counter-rotating fans without stators. Our focus is on propulsors optimized for quiet and efficient regional flights, but many elements apply to long-haul air and several other applications referred to herein.

Abstract: Systems, apparatus, and methods for implementing multi-modal transport transform generalized transport objectives for a segment of a journey from an origin to destination (e.g., as specified by a traveler or shipper) into generalized and specific transport requests to various sources/providers of transport services (e.g. operators, platforms and marketplaces) across different modes of transport. In one example, generalized and specific itineraries received from various sources/providers of transport services are managed to meet objectives, and are requested iteratively over time, up to the day of transport, to seek improvements toward meeting transport objectives. In another example, real-time monitoring of different legs of a journey across a transport segment leverages flexibility and addresses changeability options.
