DART is seen here inside its host facility, the Aero-Acoustic Propulsion Laboratory at NASA’s Glenn Research Center in Cleveland. This soundproofed chamber ensures researchers can understand the level of noise the engine is producing, as well as keeping the volume low outside.<\/div><div class=\"hds-credits\">NASA\/Bridget Caswell<\/div><\/figcaption><\/div><\/div><\/div>\n\n\n<p>Located inside a high-tech NASA laboratory in Cleveland is something you could almost miss at first glance: a small-scale, fully operational jet engine to test new technology that could <a href=\"https:\/\/www.nasa.gov\/aeronautics\/green-aero-tech\/\" target=\"_blank\" rel=\"noreferrer noopener\">make aviation more sustainable<\/a>. <\/p>\n\n\n\n<p>The engine\u2019s smaller size and modestly equipped test stand means researchers and engineers can try out newly designed engine components less expensively compared to using a more costly full-scale jet engine test rig. <\/p>\n\n\n\n<p>Named <a href=\"https:\/\/www1.grc.nasa.gov\/aeronautics\/acoustics\/testing-facilities\/dgen-aeropropulsion-research-turbofan-dart\/\" target=\"_blank\" rel=\"noreferrer noopener\">DGEN380 Aero-Propulsion Research Turbofan<\/a>, or DART, the engine is tiny enough to fit on a kitchen table, measuring at just 4.3 feet (1.3 meters) long. That\u2019s about half the length of engines used on single-aisle airliners. <\/p>\n\n\n\n<p>DART \u2013  not to be confused with NASA\u2019s <a href=\"https:\/\/science.nasa.gov\/mission\/dart\/\" target=\"_blank\" rel=\"noreferrer noopener\">asteroid redirect mission of the same name<\/a> \u2013  enables the agency to boost its sustainable aviation technology research because of its accessibility.  <\/p>\n\n\n\n<p>A hidden gem located inside the Aero-Acoustic Propulsion Laboratory at <a href=\"https:\/\/www.nasa.gov\/glenn\/\" target=\"_blank\" rel=\"noreferrer noopener\">NASA\u2019s Glenn Research Center<\/a> in Cleveland, the DART engine was made by a French company named Price Induction (now Akira) and was acquired by NASA in 2017. <\/p>\n\n\n\n<p>\u201cDART\u2019s small size makes it appealing,\u201d said Dan Sutliff, who coordinates research for the engine at NASA Glenn. \u201cIt\u2019s a great way to explore new technology that hasn\u2019t yet reached the level of a full-scale operation.\u201d <\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Small Steps Towards Big Goals<\/h3>\n\n\n\n<p>Several key NASA activities studying jet engines used DART in the past. <\/p>\n\n\n\n<p>For example, <a href=\"https:\/\/www.nasa.gov\/general\/nasa-has-helped-hush-aircraft-engine-noise-for-decades\/\" target=\"_blank\" rel=\"noreferrer noopener\">it helped researchers learn more<\/a> about incorporating materials that can help reduce engine noise. These technologies could be incorporated for use in next-generation airliners to make them quieter. <\/p>\n\n\n\n<p>Now, NASA researchers plan to use the DART engine to investigate ideas that could help develop <a href=\"https:\/\/www.nasa.gov\/directorates\/armd\/sfnp\/\" target=\"_blank\" rel=\"noreferrer noopener\">new ultra-efficient airliners<\/a> for use during the 2030s and beyond. If all goes well, the technology could proceed to more exhaustive tests involving larger facilities such as NASA\u2019s wind tunnels. <\/p>\n\n\n\n<p>\u201cDART is a critical bridge between a design and a wind tunnel test,\u201d Sutliff said. \u201cTechnologies that work well here have a greater chance of achieving successful inclusion on future aircraft engines. The test rig helps NASA save resources and contribute to protecting our environment.\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-fit \"><a href=\"https:\/\/www.nasa.gov\/wp-content\/uploads\/2024\/04\/dart-2.jpg\"><img loading=\"lazy\" decoding=\"async\" width=\"1920\" height=\"1281\" src=\"https:\/\/www.nasa.gov\/wp-content\/uploads\/2024\/04\/dart-2.jpg?w=1920\" class=\"attachment-2048x2048 size-2048x2048\" alt=\"Two people sit at a console desk and supervise data from a jet engine test.\" style=\"transform: scale(1); transform-origin: 49% 48%; object-position: 49% 48%; object-fit: cover;\" block_context=\"nasa-block\" srcset=\"https:\/\/www.nasa.gov\/wp-content\/uploads\/2024\/04\/dart-2.jpg 1920w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2024\/04\/dart-2.jpg?resize=300,200 300w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2024\/04\/dart-2.jpg?resize=768,512 768w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2024\/04\/dart-2.jpg?resize=1024,683 1024w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2024\/04\/dart-2.jpg?resize=1536,1025 1536w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2024\/04\/dart-2.jpg?resize=400,267 400w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2024\/04\/dart-2.jpg?resize=600,400 600w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2024\/04\/dart-2.jpg?resize=900,600 900w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2024\/04\/dart-2.jpg?resize=1200,801 1200w\" sizes=\"(max-width: 1920px) 100vw, 1920px\" \/><\/a><\/figure><figcaption class=\"hds-caption padding-y-2\"><div class=\"hds-caption-text p-sm margin-0\">DART tests are run from the Mobile Control Unit – a large van converted into a high-tech control facility with video monitors reporting live data from the engine.
