Sonic booms generate enormous amounts of sound energy, about 110 decibels, like the sound of an explosion or a thunderclap.<\/p>\n\n\n\n<p>Through the unique design of the X-59 Quiet SuperSonic Technology (QueSST) airplane, NASA aims to reduce the sonic boom to make it much quieter.<\/p>\n\n\n\n<p>Engineers with the agency\u2019s Commercial Supersonic Technology (CST) project recently used a small-scale model of the X-59 in <a href=\"https:\/\/www.nasa.gov\/centers\/glenn\/home\/index.html\">NASA Glenn’s<\/a> 8- by 6-foot Supersonic Wind Tunnel to visualize the agency\u2019s boom-reducing technology and validate its boom-predicting capabilities.<\/p>\n\n\n\n<p>\u201cThis is the team\u2019s opportunity to get data at the low sound levels produced in the tunnel,\u201d said Clayton Meyers, deputy project manager of the CST project. \u201cIt all comes down to our ability to measure the thump.\u201d<\/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-none \"><a href=\"https:\/\/www.nasa.gov\/wp-content\/uploads\/2022\/01\/grc-2021-c-02732_1.jpg\"><img loading=\"lazy\" decoding=\"async\" width=\"2048\" height=\"1445\" src=\"https:\/\/www.nasa.gov\/wp-content\/uploads\/2022\/01\/grc-2021-c-02732_1.jpg?w=2048\" class=\"attachment-2048x2048 size-2048x2048\" alt=\"The X-59 model is shown from below, inside the wind tunnel.\" style=\"transform: scale(1); transform-origin: 50% 50%; object-position: 50% 50%; object-fit: cover;\" block_context=\"nasa-block\" srcset=\"https:\/\/www.nasa.gov\/wp-content\/uploads\/2022\/01\/grc-2021-c-02732_1.jpg 6000w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2022\/01\/grc-2021-c-02732_1.jpg?resize=300,212 300w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2022\/01\/grc-2021-c-02732_1.jpg?resize=768,542 768w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2022\/01\/grc-2021-c-02732_1.jpg?resize=1024,723 1024w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2022\/01\/grc-2021-c-02732_1.jpg?resize=1536,1084 1536w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2022\/01\/grc-2021-c-02732_1.jpg?resize=2048,1445 2048w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2022\/01\/grc-2021-c-02732_1.jpg?resize=400,282 400w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2022\/01\/grc-2021-c-02732_1.jpg?resize=600,423 600w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2022\/01\/grc-2021-c-02732_1.jpg?resize=900,635 900w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2022\/01\/grc-2021-c-02732_1.jpg?resize=1200,847 1200w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2022\/01\/grc-2021-c-02732_1.jpg?resize=2000,1411 2000w\" sizes=\"(max-width: 2048px) 100vw, 2048px\" \/><\/a><\/figure><figcaption class=\"hds-caption padding-y-2\"><div class=\"hds-caption-text p-sm margin-0\">The X-59 small-scale model is seen in NASA Glenn\u2019s 8- by- 6-foot Supersonic Wind Tunnel. The model was inverted with the shock wave sensor array mounted on the tunnel\u2019s ceiling during the testing.<\/div><div class=\"hds-credits\">Credits: NASA<\/div><\/figcaption><\/div><\/div><\/div>\n\n\n<p>The model\u2014measuring about a foot and a half in length\u2014was subjected to weeks of testing in the tunnel, producing shock waves that were captured by special cameras mounted outside the test section and by a unique sensor array inside. The unique schlieren images from the cameras provide engineers with a visualization of the shock waves and their positions as air passes around the model. The sensor provides detailed measurement of the strength of the shocks. Results from the tests are encouraging, as the shock waves produced by the model were a match, in both position and strength, to those from earlier computer models for quieter supersonic flight.<\/p>\n\n\n\n<p>Schlieren imagery and pressure measurement are both critical to NASA\u2019s ability to compare wind tunnel data with computer modeling. These capabilities improve the team\u2019s capacity to understand and predict actual sonic thumps during future X-59 flights. NASA has also developed <a href=\"https:\/\/www.nasa.gov\/centers\/armstrong\/feature\/NASA_advances_schlieren_imagery_for_supersonic_aircraft.html\">s<\/a><a href=\"https:\/\/www.nasa.gov\/centers\/armstrong\/feature\/NASA_advances_schlieren_imagery_for_supersonic_aircraft.html\">chlieren imaging capabilities for flight<\/a> that will also be used during upcoming flight campaigns.<\/p>\n\n\n\n<p>\u201cWith the X-59, we want to demonstrate that we can reduce the annoying sonic booms to something much quieter, referred to as \u2018sonic thumps,\u2019\u201d said John Wolter, lead researcher on the X-59 sonic boom wind tunnel test. \u201cThe goal is to provide noise and community response data to regulators, which could result in new rules for overland supersonic flight. The test proved that we don\u2019t just have quieter aircraft design, but that we also have the accurate tools needed to predict the noise of future aircraft.\u201d<\/p>\n\n\n\n<p>The model will travel to Tokyo in March for additional wind tunnel verification testing with the Japan Aerospace Exploration Agency and Boeing.<\/p>\n\n\n\n<p>NASA and Lockheed Martin are currently finalizing the build of the X-59 at the Skunkworks facility in California. In late 2022, NASA and Lockheed Martin will begin initial flight tests to prove airworthiness. Following flight testing, NASA will then verify that the aircraft\u2019s quiet supersonic technology performs in flight as designed before transitioning to the community overflight phase.  <\/p>\n\n\n\n<p><strong><em>Doreen Zudell with Jimi Russell<\/em><\/strong><br><em><strong>NASA’s Glenn Research Center<\/strong><\/em><\/p>\n\n\n<div id=\"\" class=\"nasa-gb-align-full width-full maxw-full padding-x-3 padding-y-0 hds-module hds-module-full wp-block-nasa-blocks-related-articles\">\t\t<section class=\"hds-related-articles padding-x-0 padding-y-3 desktop:padding-top-7 desktop:padding-bottom-9\">\n\t\t\t<div class=\"w-100 grid-row grid-container maxw-widescreen padding-0 text-align-left\">\n\t\t\t\t<div class=\"margin-bottom-4\"><h2 style=\"max-width: 100%;\" class=\"width-full w-full maxw-full\">Explore More<\/h2><\/div>\n\t\t\t<\/div>\n\t\t\t<div class=\"grid-row grid-container maxw-widescreen padding-0\">\n\t\t\t\t\t\t\t\t\t\t<div class=\"grid-col-12 desktop:grid-col-4 margin-bottom-4 desktop:margin-bottom-0 desktop:padding-right-3\">\n\t\t\t\t\t\t<a href=\"https:\/\/science.nasa.gov\/earth\/natural-disasters\/nasa-announces-new-system-to-aid-disaster-response\/\" class=\"color-carbon-black\" rel=\"noopener\">\n\t\t\t\t\t\t\t<div class=\"margin-bottom-2\">\n\t\t\t\t\t\t\t\t<div class=\"hds-cover-wrapper cover-hover-zoom bg-carbon-black minh-mobile\">\n\t\t\t\t\t\t\t\t<figure class=\"hds-media-background  \"><img decoding=\"async\" loading=\"lazy\" alt=\"\" style=\"transform: scale(1);
