The U.S. Department of Defense\u2019s Strategic Environmental Research and Development Program (SERDP), the DoD\u2019s environmental science and technology program, is supporting a one-year, $200,000 effort at KU, with the potential to expand that support in the years ahead.<\/p>\n<p>\u201cThis project will test ideas to reduce <a href=\"https:\/\/phys.org\/tags\/jet+noise\/\" rel=\"tag\" class=\"\">jet noise<\/a> from supersonic military aircraft,\u201d said Z.J. Wang, Spahr Professor of Aerospace Engineering at KU, who is heading the new effort. \u201cAt the moment, the noise is so loud that it affects the health of personnel working in close proximity to the aircraft and people living close to the military base. This is a challenging problem, and we\u2019ve suggested some novel ideas which have potential.\u201d<\/p>\n<p><!-- Link: <a href=\"https:\/\/phys.org\/news\/2019-03-aims-noise-supersonic-military-jets.html\">https:\/\/phys.org\/news\/2019&#45;03-aims-noise-supersonic-military-jets.html<\/a> --><\/p>\n","protected":false},"excerpt":{"rendered":"<p>It\u2019s clich\u00e9 to describe something very noisy as \u201clouder than a jet engine.\u201d But supersonic jet engines, like those powering fighters flown by the U.S. military, are so much louder than regular jet engines that scientists have a special term for their sound\u2014\u201d broadband shock-associated noise.\u201d Now, a team of faculty and students from the [\u2026]<\/p>\n","protected":false},"author":513,"featured_media":0,"comment_status":"open","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[38,1495,9],"tags":[],"class_list":["post-88815","post","type-post","status-publish","format-standard","hentry","category-engineering","category-health","category-military"],"_links":{"self":[{"href":"https:\/\/lifeboat.com\/blog\/wp-json\/wp\/v2\/posts\/88815","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/lifeboat.com\/blog\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/lifeboat.com\/blog\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/lifeboat.com\/blog\/wp-json\/wp\/v2\/users\/513"}],"replies":[{"embeddable":true,"href":"https:\/\/lifeboat.com\/blog\/wp-json\/wp\/v2\/comments?post=88815"}],"version-history":[{"count":0,"href":"https:\/\/lifeboat.com\/blog\/wp-json\/wp\/v2\/posts\/88815\/revisions"}],"wp:attachment":[{"href":"https:\/\/lifeboat.com\/blog\/wp-json\/wp\/v2\/media?parent=88815"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/lifeboat.com\/blog\/wp-json\/wp\/v2\/categories?post=88815"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/lifeboat.com\/blog\/wp-json\/wp\/v2\/tags?post=88815"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
