“
NASA’s Advanced Air Mobility mission is developing design tools that manufacturers can use to reduce noise impacts. The Advanced Air Mobility (AAM) project and Revolutionary Vertical Lift Technology project work together to conduct testing with industry partners. The data NASA collects and analyzes from these tests with electric vertical take-off and landing aircraft (eVTOLs) will ensure that the agency’s aircraft design tools correctly predict noise levels for these types of vehicles. With tools that predict noise correctly, manufacturers can design vehicles for quiet operation in urban and rural areas.
The data will also help define and optimize AAM routes and low-noise flight paths for community needs and assist the Federal Aviation Administration (FAA) in creating policy. Lessons learned through these tests will inform the FAA’s ongoing work with operations and airspace integration.”
