The racket had woken up the entire neighborhood.<\/p>\n\n\n\n<p>While engineers at the Lewis Flight Propulsion Laboratory rejoiced at the successful testing of a ramjet at twice the speed of sound in the newly opened <a href=\"https:\/\/www1.grc.nasa.gov\/facilities\/8x6\/\" rel=\"noopener\">8-by 6-Foot Supersonic Wind Tunnel<\/a>, the loud roar and rattling windows woke residents up to five miles away. Some thought the center had been bombed.<\/p>\n\n\n\n<p>After assuring the community that all was safe, NACA officials began working feverishly to understand the problem.<\/p>\n\n\n\n<p>The laboratory decided to repeat the test on the following Saturday afternoon so measurements could be made in the surrounding area.

Carome measure ground vibrations on West 220th Street caused by the operation of the 8- by 6-Foot Supersonic Wind Tunnel at the National Advisory Committee for Aeronautics (NACA) Lewis Flight Propulsion Laboratory. The 8-by-6 was the laboratory\u2019s first large supersonic wind tunnel. It was also the NACA\u2019s most powerful supersonic tunnel, and the NACA\u2019s first facility capable of running an engine at supersonic speeds. The 8-by-6 was originally an open-throat and non-return tunnel. This meant that the supersonic air flow was blown through the test section and out the other end into the atmosphere. Complaints from the local community led to the installation of a muffler at the tunnel exit and the eventual addition of a return leg. Reverend Brikenhauer, a seismologist, and Carome, an electrical technician were brought in from John Carroll University to take vibration measurements during the 8-by-6-foot tunnel\u2019s first run with a supersonic engine. They found that the majority of the vibrations came from the air and not the ground. The tunnel\u2019s original muffler offered some relief during the facility checkout runs, but it proved inadequate during the operation of an engine in the test section. Tunnel operation was suspended until a new muffler was designed and installed. The NACA researchers, however, were pleased with the tunnel\u2019s operation. They claimed it was the first time a jet engine was operated in an airflow faster than Mach 2.<\/div><div class=\"hds-credits\">NASA<\/div><\/figcaption><\/div><\/div><\/div>\n\n\n<p>The impact was more significant than anticipated. The sound emanating from both the supersonic air flow in the tunnel and the operation of the engine produced both low frequencies that rattled windows and high frequencies that produced objectionable noise.<\/p>\n\n\n\n<p>Sharp, who closely monitored the proceedings, ceased all engine testing in the new multi-million-dollar facility until the problem was resolved. NACA engineers worked with the MIT team to develop a solution.<\/p>\n\n\n\n<p>They explored a range of mitigation devices on a subscale model of the tunnel. The basic design for the new muffler section was finalized within four months, and the addition was in place by August 1950.<\/p>\n\n\n\n<p>The new 50-foot tall and 190-foot long concrete structure was connected to the tunnel exit at a 90-degree angle. It contained six large ducts which gradually slowed the airflow. Each duct contained resonator chambers to muffle the sound and vibrations and perforated panels to mitigate higher frequency vibrations.<\/p>\n\n\n\n<p>The flow was then redirected at another right angle and discharged into the atmosphere in the opposite direction of nearby residents. <\/p>\n\n\n\n<p>Lewis successfully demonstrated the muffler\u2019s effectiveness on December 14, 1950, and the 8-by 6 immediately commenced its propulsion testing. The community, and Sharp\u2019s mother, were appeased.<\/p>\n\n\n\n<p>Over the ensuing decades, the 8-by 6 has tested propulsion systems for a variety of ramjet engines, the Saturn rocket, Space Shuttle, and a variety of military and civilian aircraft.<\/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:\/\/www.nasa.gov\/wp-content\/uploads\/2021\/05\/grc-1950-c-26416-e1678726594584.jpg\"><img loading=\"lazy\" decoding=\"async\" width=\"1420\" height=\"1775\" src=\"https:\/\/www.nasa.gov\/wp-content\/uploads\/2021\/05\/grc-1950-c-26416-e1678726594584.jpg?w=1420\" class=\"attachment-2048x2048 size-2048x2048\" alt=\"Workers stand inside wind tunnel openings at three vertical levels.\" 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\/2021\/05\/grc-1950-c-26416-e1678726594584.jpg 1420w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2021\/05\/grc-1950-c-26416-e1678726594584.jpg?resize=240,300 240w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2021\/05\/grc-1950-c-26416-e1678726594584.jpg?resize=768,960 768w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2021\/05\/grc-1950-c-26416-e1678726594584.jpg?resize=819,1024 819w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2021\/05\/grc-1950-c-26416-e1678726594584.jpg?resize=1229,1536 1229w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2021\/05\/grc-1950-c-26416-e1678726594584.jpg?resize=320,400 320w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2021\/05\/grc-1950-c-26416-e1678726594584.jpg?resize=480,600 480w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2021\/05\/grc-1950-c-26416-e1678726594584.jpg?resize=720,900 720w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2021\/05\/grc-1950-c-26416-e1678726594584.jpg?resize=960,1200 960w\" sizes=\"(max-width: 1420px) 100vw, 1420px\" \/><\/a><\/figure><figcaption class=\"hds-caption padding-y-2\"><div class=\"hds-caption-text p-sm margin-0\">The six concrete passages in the new acoustical housing addition to the 8 x 6 wind tunnel contained resonators to muffle noise during testing.
