ATAC — National Aeronautics and Space Administration SBIR Phase I: A3

Description

<p>The proposed SBIR develops a near real-time aircraft noise monitoring tool called UAM Noise Integration Tool (UNIT) for e-VTOL aircraft that is capable of being integrated within the real-time NASA ATM-X Testbed environment. It is highly relevant to the NASA 2018 SBIR Focus Area 20, Subtopic A3.01 Advanced Air Traffic Management Systems Concepts, since it addresses the area of &ldquo;achieving high efficiency in using aircraft, airports, enroute and terminal airspace resources, while accommodating an increasing variety of missions and vehicle types, including wide-spread integration of UAS and ODM operations&rdquo; because noise can be a greatly limiting factor in determining efficiencies, due to the expected high frequency of ODM operations and the potential noise impacts on communities. Specifically, it is relevant to the RFP area of &ldquo;concepts of emergent risks&rdquo; because increased noise impacts are a risk to the system, and public backlash to ODM and e-VTOL noise impacts can thwart the concept and technology before it launches. 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. NASA&rsquo;s Parimal Kopardekar, has stated on more than one occasion that noise is one of the top three challenges for UAM. UNIT provides noise results within a real-time environment to be used as input parameters into flight path optimization algorithms to minimize population noise impacts, thereby increasing public acceptance of UAM.&nbsp; This capability is important because communities are highly sensitive to noise and have blocked change when they believe their rights have been inadequately addressed</p>
