Aviation Systems Division Participates in the Vertical Flight Society Transformative Vertical Flight 2020 Meeting
February 6, 2020

The Vertical Flight Society (VFS) Transformative Vertical Flight 2020 meeting was held January 21-23 in San Jose, CA. The meeting hosted approximately 60 technical presentations on topics including aerodynamics, acoustics, Urban Air Mobility (UAM) design and configurations, and electric Vertical Takeoff and Landing (eVTOL) performance. In addition, panels were held on topics such as manufacturing, crashworthiness, infrastructure, ridesharing, and cargo delivery. Keynote speakers from government, industry, and academia, represented organizations from the Federal Aviation Administration (FAA), U.S. Army, White House Office of Science and Technology Policy, Uber, and Bell Helicopter. The Air Traffic Management Exploration (ATM-X) project team participated and explored potential collaboration opportunities and gained a wide range of perspectives to help shape ATM-X UAM research. Noise impacts continue to be a top concern of industry and the UAM community at large. The investor panel emphasized the need to focus on infrastructure, including airspace access to enable UAM operations.

ATM-X UAM X2 Completion
February 6, 2020

The Air Traffic Management Exploration (ATM-X) Urban Air Mobility (UAM) team completed development and delivery of the initial UAM airspace system (X2) software with the delivery of documentation and reporting of analysis results on December 23, 2019. The X2 system supports NASA’s UAM Grand Challenge - Development Test (GC-DT) flight activities, starting during the Spring of 2020. X2 integrated components of NASA’s Unmanned Aircraft Systems Traffic Management (UTM) system and ATM-X’s Testbed platform, with enhancements to enable the density, tempo, and complexity of anticipated UAM operations. As part of X2 development, NASA collaborated with Uber on a series of engineering evaluations. From the engineering evaluations, additional improvements were made to configuration management, enhance system performance, increase system capacity, raise system resilience, and add verification and validation capabilities. The enhanced X2 system was successfully tested during internal tests in December 2019, with the NASA Grand Challenge Airspace Test Infrastructure (ATI) team, in preparation for GC-DT flight activities. The ATM-X UAM team will continue to develop and mature the UAM airspace system in support of GC-1 (the follow-up to GC-DT) in 2022, conducting engineering simulations on GC scenarios in summer 2020 (X3) and summer 2021 (X4) with additional industry partners.

ATD-2 Benefits Have Reached 100,000 Urban Trees Milestone
February 6, 2020

Benefits totals from Phases 1 and 2 of the ATD-2 field demonstration at Charlotte Douglas International Airport (September 29, 2017 through January 31, 2020.) Saved 652,613 gallons of fuel. Saved 13,487,415 pounds of carbon dioxide, which is equivalent to 100,292 urban trees. Saved 3,317 hours of engine run time. Reduced delay by 557 hours. Saving passengers an estimated $2,673,697 in value of time and operators an estimated $757,627 in flight crew costs.
Benefits totals from ATD-2 Field Demonstration.

As of January 31, 2020, the NASA Airspace Technology Demonstration 2 (ATD-2) team has achieved an environmental benefit milestone equivalent to the planting of 100,000 urban trees, from the ATD-2 field demonstration at Charlotte Douglas International Airport. The benefits estimates were based on formulae developed by the US Environmental Protection Agency (EPA). Through ATD-2 recommended actions, such as holding departures at gates through surface metering during peak periods, pre-scheduling the approval request (APREQ) flights at gates, as well as renegotiating the release times of APREQ flights while taxiing through ATD-2 Integrated Departure Arrival Capabilities (IDAC), ATD-2 operations have saved over 652,000 gallons of fuel, reduced engine run times by more than 3,300 hours, and reduced 13.5 million pounds of CO2 emission. This amount of CO2 savings is equivalent to planning 100,292 urban trees. The detailed calculations and additional operational benefits are described in the figure above.
