Urban Air Mobility Noise Integration Tool (UNIT) SBIR
With increasing emphasis on enabling Urban Air Mobility (UAM) concepts to increase efficiency of the National Airspace System by NASA’s Aeronautics Research Mission Directorate (ARMD) in its Air Traffic Management – eXploration (ATM-X) project and from private industry initiatives like Uber Elevate, it is essential that environmental modeling tools be developed to help overcome some of the key barriers to UAM, especially when low-altitude NAS changes will require environmentally-driven approvals. One of the major barriers is community noise impacts from UAM aircraft operations.
ATAC is developing a near real-time aircraft noise monitoring tool called UAM Noise Integration Tool (UNIT) for electric Vertical Take-Off and Landing (e-VTOL) aircraft that will be capable of integrating within the real-time NASA ATM-X Testbed environment. There are three parts to the innovation: (1) the ability to calculate in near real-time the noise impacts at any location using both real-time and predicted flight operations and trajectories, (2) the ability to model the noise of conceptual e-VTOL aircraft, and (3) the development of people-focused noise metrics that consider the movement of people throughout the day.
