To confirm the X-59\u2019s ability to fly supersonic while only producing quiet sonic \u201cthumps,\u201d NASA needs to be able to record these sounds from the ground. The agency recently completed tests aimed at understanding equipment and procedures needed to make those recordings.<\/p>\n\n\n\n<p>NASA\u2019s Carpet Determination In Entirety Measurements (CarpetDIEM) flights examined the quality and ruggedness of a new generation of ground recording systems, focusing on how to deploy the systems for X-59 testing, and retrieve the data they collect. In all, researchers set up 10 microphone stations over a 30-mile stretch of desert near NASA\u2019s Armstrong Flight Research Center in Edwards, California.<\/p>\n\n\n\n<p>\u201cWe\u2019re trying to answer questions like how many people does it take to go out and service these instruments on a daily basis, how to get the data back, how many vehicles are needed \u2013 all those sorts of things on how we operate,\u201d said Dr. Forrest Carpenter, principal investigator for the third flight series, known as CarpetDIEM III. \u201cWe\u2019re kind of learning how to dance now so that when we get to the big dance, we\u2019re ready to go.\u201d<\/p>\n\n\n\n<p>The X-59 itself is not yet flying, so using an F-15 and an F-18 from NASA Armstrong, the CarpetDIEM III testing involved 20 supersonic passes with speeds ranging from Mach 1.15 to Mach 1.4, at altitudes ranging from 40,000 to 53,000 feet. Three of the passes involved an F-18 conducting a special inverted dive maneuver to simulate a quiet sonic boom, with one getting as quiet as 67 perceived level decibels, a measure of the perceived noisiness of the jet for an observer on the ground.<\/p>\n\n\n<div id=\"\" class=\"hds-media hds-module wp-block-image\"><div class=\"margin-left-auto margin-right-auto nasa-block-align-inline\"><div class=\"hds-media-wrapper margin-left-auto margin-right-auto\"><figure class=\"hds-media-inner hds-cover-wrapper hds-media-ratio-fit \"><a href=\"https:\/\/images-assets.nasa.gov\/image\/AFRC2024-0008-008\/AFRC2024-0008-008~large.jpg?w=1920&h=1280&fit=clip&crop=faces%2Cfocalpoint\" rel=\"noopener\"><img fetchpriority=\"high\" decoding=\"async\" width=\"1920\" height=\"1280\" src=\"https:\/\/images-assets.nasa.gov\/image\/AFRC2024-0008-008\/AFRC2024-0008-008~large.jpg?w=1920&h=1280&fit=clip&crop=faces%2Cfocalpoint\" class=\"attachment-2048x2048 size-2048x2048\" alt=\"\" style=\"transform: scale(1); transform-origin: 50% 50%; object-position: 50% 50%; object-fit: cover;\" block_context=\"nasa-block\" srcset=\"https:\/\/images-assets.nasa.gov\/image\/AFRC2024-0008-008\/AFRC2024-0008-008~large.jpg?w=1920&h=1280&fit=crop&crop=faces%2Cfocalpoint 1920w, https:\/\/images-assets.nasa.gov\/image\/AFRC2024-0008-008\/AFRC2024-0008-008~large.jpg?w=300&h=200&fit=crop&crop=faces%2Cfocalpoint 300w, https:\/\/images-assets.nasa.gov\/image\/AFRC2024-0008-008\/AFRC2024-0008-008~large.jpg?w=768&h=512&fit=crop&crop=faces%2Cfocalpoint 768w, https:\/\/images-assets.nasa.gov\/image\/AFRC2024-0008-008\/AFRC2024-0008-008~large.jpg?w=1024&h=683&fit=crop&crop=faces%2Cfocalpoint 1024w, https:\/\/images-assets.nasa.gov\/image\/AFRC2024-0008-008\/AFRC2024-0008-008~large.jpg?w=1536&h=1024&fit=crop&crop=faces%2Cfocalpoint 1536w, https:\/\/images-assets.nasa.gov\/image\/AFRC2024-0008-008\/AFRC2024-0008-008~large.jpg?w=400&h=267&fit=crop&crop=faces%2Cfocalpoint 400w, https:\/\/images-assets.nasa.gov\/image\/AFRC2024-0008-008\/AFRC2024-0008-008~large.jpg?w=600&h=400&fit=crop&crop=faces%2Cfocalpoint 600w, https:\/\/images-assets.nasa.gov\/image\/AFRC2024-0008-008\/AFRC2024-0008-008~large.jpg?w=900&h=600&fit=crop&crop=faces%2Cfocalpoint 900w, https:\/\/images-assets.nasa.gov\/image\/AFRC2024-0008-008\/AFRC2024-0008-008~large.jpg?w=1200&h=800&fit=crop&crop=faces%2Cfocalpoint 1200w\" sizes=\"(max-width: 1920px) 100vw, 1920px\" loading=\"eager\" \/><\/a><\/figure><figcaption class=\"hds-caption padding-y-2\"><div class=\"hds-caption-text p-sm margin-0\">Aerospace engineer Larry Cliatt, Quesst Phase 2 sub-project manager and technical lead for the acoustic validation phase of the Quesst mission, sets up a ground recording system in the California desert. The Quesst mission recently completed testing of operations and equipment to be used in recording the sonic thumps of the X-59. The testing was the third phase of Carpet Determination in Entirety Measurements flights, called CarpetDIEM for short. An F-15 and an F-18 from NASA\u2019s Armstrong Flight Research Center in Edwards, California, created sonic booms, both loud and soft, to verify the operations of ground recording systems spread out across 30 miles of open desert.<\/div><div class=\"hds-credits\">NASA\/Steve Freeman<\/div><\/figcaption><\/div><\/div><\/div>\n\n\n<p>\u201cWe expect the X-59 sonic thump to be as low as about 75 perceived loudness decibels,\u201d said Larry Cliatt, sub-project manager for the Quesst acoustic validation phase. \u201cThat is a lot quieter than the Concorde, which was over 100 perceived loudness decibels.\u201d<\/p>\n\n\n\n<p>In order to measure these very quiet sonic thumps, the ground recording systems used in the CarpetDIEM flights were calibrated to measure as low as about 50 perceived loudness decibels \u2013 the equivalent to being in the room with a running refrigerator.<\/p>\n\n\n\n<p>CarpetDIEM III also validated the use of Automatic Dependent Surveillance-Broadcast, an existing technology flown on all commercial aircraft and most private aircraft to report speed and position.

Given the performance of the systems, the team will assess whether they need to visit all the sites every day of Phase 2 testing.<\/p>\n\n\n\n<p>The team also learned about the coordination and documentation processes needed for such research, both with internal organizations, such as NASA Armstrong\u2019s Environmental and Safety offices, and with outside parties including:<\/p>\n\n\n\n<ul>\n<li>The U.S. Bureau of Land Management, which gave approval to use public lands for the testing<\/li>\n\n\n\n<li>Law enforcement, which helped secure the test
