Operations limits for passenger-carrying Urban Air Mobility missions
Principal-investigators: Dr. Daniel DeLaurentis, Dr. William Crossley
Sponsor: National Institute of Aerospace, NASA Langley Research Center
Synopsis: The convergence of new technologies, such as electric propulsion, autonomy, and new business models, such as app-based ride sharing, are generating the potential for a new aviation market known as Urban Air Mobility (UAM) to emerge. It is envisioned that UAM may revolutionize mobility within metropolitan areas by enabling a safe, efficient, convenient, affordable, and accessible air transportation system for passengers and cargo. Such an air transportation system could bring aviation into people’s daily lives and provide an augmentation and/or alternative to other ground-based transit modes, such as cars. The UAM market is not likely to appear overnight. Rather, some form of evolutionary approach based on the pace of technology development, infrastructure limitations, societal acceptance, airspace integration, and many other factors may bring us from the current state of the art to the envisioned future state where aviation is a normal part of people’s daily lives. To help NASA’s Aeronautics Research Mission Directorate (ARMD) consider potential near-term applications for passenger-carrying UAM and which issues will be the key “bottlenecks” limiting the scalability of early UAM operations, this task is focused on studying the “operational limits” of near-term UAM applications. The work builds upon previous methodology developments of the Purdue PIs to assess the mobility benefits from CTOL and VTOL operations, at a regional transportation level and with initial “hooks” into urban areas.

Secure and Safe Assured Autonomy (S2A2)
Sponsor:NASA University Leadership Initiative
Synopsis: The recent introduction of unmanned systems into the NAS will bring challenges and opportunities for the nation’s aviation system. The integration of such a complex transportation system creates a clear need to develop new technologies and innovative operational concepts for secure and safe assured autonomy. An unmanned systems future will see the integration of a wide variety of Unmanned Aerial Systems (UAS), personal air vehicles, Urban Air Mobility (UAM) vehicles, and cargo and special mission aircraft into the NAS. These developments can leverage UAS Traffic Management (UTM) advancements for the unique requirements of UAM airspace management. The main challenges include: (i) sensing and understanding complex operational surroundings, coordinating different types of aerial vehicles, planning and navigation through highly dynamic and uncertain environments; (ii) securing the NAS against a wide range of malicious adversarial threats, specifically cyber-physical attacks; (iii) verifying and validating autonomous system operation; and, finally, (iv) properly integrating new vehicles and traffic management approaches in the midst of autonomy. Our primary goal is to ensure safe, secure and robust integration of autonomous vehicles into a UAM-tailored transportation infrastructure while maintaining compliance with existing commercial and civil air transportation safety standards.

Aircraft Technology Modeling and Assessment - NextGen Supersonic Fleet evaluation
Principal-investigator: Dr. William Crossley
Co-investigator: Dr. Daniel DeLaurentis
Sponsor: FAA ASCENT Center of Excellence
Synopsis: The project is focused on developing a model that measures fleet-wide environmental impact from new aircraft concepts and technologies under various carbon policy scenarios, based on an approach that mimics airline behavior. Fleet-level Environmental Evaluation Tool (FLEET) considers uses a "system dynamics-like" approach to allow demand, fleet size/composition, and fares to evolve over time while considering scenarios with varying technological, policy, & economic factors. The current focus is a collaborative effort between Georgia Institute of Technology and Purdue University to leverage capabilities and knowledge available from the multiple entities that make up the ASCENT university partners and advisory committee. Purdue's primary directive for this research project is to support the Federal Aviation Administration (FAA) in modeling and assessing the potential future evolution of the next-generation supersonic aircraft fleet. Purdue's research under this project consists of three integrated focus areas: (a) establishing fleet assumptions and performing demand assessment; (b) performing preliminary SST environmental impact prediction; (c) performing vehicle and fleet assessments of potential future supersonic aircraft. More details are available at the project website.
