Hill Air Force Base near Ogden, Utah, is home to the Air Force Material Command\u2019s Ogden Air Logistics Complex (OO-ALC). The OO-ALC performs programmed depot maintenance on a number of US Air Force weapon systems, including the F-16 Fighting Falcon. The F-16 jets are periodically serviced and repainted. The jets are brought into the shop and sealants need to be removed from the jet\u2019s wings before they are repainted with fuel-resistant paint. To remove sealant from F-16 wings, the 574th Aircraft Maintenance Squadron (AMXS) was manually scraping with abrasive scrapers.<\/p>\n
<\/p>\n
The process used to remove the sealant from the wings was very time consuming, labor intensive and occasionally damaged the paint. To remove the sealant properly, a crew member needed to crawl into a hole and scrape the wings while upside down. This was not only physically strenuous and inefficient, but it also raised the possibility of a crew member being injured.<\/p>\n
<\/p>\n
\n\u201cScraping an entire F-16 wing takes four shifts and three to four people per shift,\u201d said Dennis Hathaway, F-16 Wing Shop Supervisor. \u201cScraping sealant by hand is one of the worst jobs for a sheet metal mechanic. It is very labor intensive and can potentially cause carpal tunnel syndrome.\u201d<\/p>\n<\/blockquote>\n
<\/p>\n
THE SOLUTION<\/span><\/p>\n
The 574th AMXS crew began to search for alternative methods to improve their F-16 maintenance program. The crew tested a Cold Jet dry ice blasting machine.<\/p>\n
Cold Jet dry ice cleaning systems use non-abrasive media in the form of recycled CO2 pellets that will not damage surfaces or equipment. The combination of dry ice cleaning\u2019s kinetic energy and thermal effect causes material, such as the sealant, to shrink and lose adhesion from the subsurface, lifting away the sealant. Unlike blasting with other media, dry ice cleaning does not leave any secondary waste, because the dry ice particles sublimate upon impact \u2013 converting from solid to gas. Dry ice cleaning is safe and non-toxic, does not create downstream contamination and reduces or eliminates employee exposure to dangerous chemical cleaning agents.<\/p>\n
<\/p>\n
THE RESULTS<\/h4>\n
Using the Cold Jet Aero 75, an entire F-16 wing could be blasted in four shifts by only one person. To remove the sealant, the pellets are driven at 1.5 kg – (3.5 lbs) per minute. The machine is capable of operating at 0 to 3.2 kg – (0 to 7lbs) per minute. The dry ice is blasted through a blast swath nozzle using building-supplied air pressure at 5.5 bar (80 psi).<\/p>\n
<\/p>\n
\n\u201cWith the blast pressure adjusted to 3.5 pounds per minute, dry ice pellets remove only the sealant and not the paint,\u201d said Marion Long, 574th AMXS Structures Section Chief. \u201cUsing Cold Jet dry ice blasting is so much easier. The sealer is in a dry state, so once it\u2019s removed, it can be swept up and placed in the trash. There\u2018s no biohazard or bead media to contain, and it\u2019s safe to use on aluminum as thin as 0.0762 cm (30\/1000ths of an inch).\u201d<\/p>\n<\/blockquote>\n
<\/p>\n
The Air Force base not only found the Cold Jet machine to be more efficient, but also more cost effective.<\/p>\n
<\/p>\n
\n\u201cIn man-hours, the machine was almost paid for after the first use,\u201d said Hathaway. \u201cThe shop does six or seven wing skins per year; now all will be done by dry ice blasting instead of scraping.\u201d<\/p>\n<\/blockquote>\n
<\/p>\n
The dry ice cleaning process is also much safer for the crew members. The process eliminates the risk of sustaining an injury through strenuous manual scrubbing.<\/p>\n","client_name":"Hill Air Force Base"},"seo":{"title":"Air Force base quickly and safely removes sealant from F-16 jet wing","description":"","canonical":"https:\/\/www.coldjet.com\/es\/resources\/hill-air-force-base\/","robots":{"noindex":false,"nofollow":false,"directives":["index","follow","max-image-preview:large","max-snippet:-1","max-video-preview:-1"],"raw":"index, follow, max-image-preview:large, max-snippet:-1, max-video-preview:-1"},"og":{"title":"Air Force base quickly and safely removes sealant from F-16 jet wing","description":"","image":"","image_id":null,"type":"article","url":"https:\/\/www.coldjet.com\/es\/resources\/hill-air-force-base\/","locale":"es_ES","site_name":"Cold Jet","article_modified":"2020-03-11 16:57:27+00:00","article_published":"2019-07-01 18:16:36+00:00"},"twitter":{"card":"summary_large_image","title":"Air Force base quickly and safely removes sealant from F-16 jet wing","description":"","image":"","image_id":null,"creator":"","site":""},"hreflang":[{"lang":"en-US","url":"https:\/\/www.coldjet.com\/resources\/hill-air-force-base\/","lang_code":"en","locale":"en_US","is_default":true},{"lang":"nl-NL","url":"https:\/\/www.coldjet.com\/nl\/resources\/hill-air-force-base\/","lang_code":"nl","locale":"nl_NL"},{"lang":"de-DE","url":"https:\/\/www.coldjet.com\/de\/resources\/luftwaffenstuetzpunkt-entfernt-schnell-und-sicher-dichtstoff-vom-f-16-jet-fluegel\/","lang_code":"de","locale":"de_DE"},{"lang":"it-IT","url":"https:\/\/www.coldjet.com\/it\/resources\/hill-air-force-base\/","lang_code":"it","locale":"it_IT"},{"lang":"ja","url":"https:\/\/www.coldjet.com\/ja\/resources\/hill-air-force-base\/","lang_code":"ja","locale":"ja"},{"lang":"pt-BR","url":"https:\/\/www.coldjet.com\/pt-br\/resources\/hill-air-force-base\/","lang_code":"pt-br","locale":"pt_BR"},{"lang":"es-ES","url":"https:\/\/www.coldjet.com\/es\/resources\/hill-air-force-base\/","lang_code":"es","locale":"es_ES"},{"lang":"x-default","url":"https:\/\/www.coldjet.com\/resources\/hill-air-force-base\/","lang_code":"en"}],"schema":{"@context":"https:\/\/schema.org","@graph":[{"@type":"Article","@id":"https:\/\/www.coldjet.com\/es\/resources\/hill-air-force-base\/#article","isPartOf":{"@id":"https:\/\/www.coldjet.com\/es\/resources\/hill-air-force-base\/"},"author":{"name":"mcaminiti","@id":"https:\/\/www.coldjet.com\/es\/#\/schema\/person\/d44651a8d83c912d7ff841f0dae7199d"},"headline":"Air Force base quickly and safely removes sealant from F-16 jet wing","datePublished":"2019-07-01T18:16:36+00:00","dateModified":"2020-03-11T16:57:27+00:00","mainEntityOfPage":{"@id":"https:\/\/www.coldjet.com\/es\/resources\/hill-air-force-base\/"},"wordCount":12,"commentCount":0,"publisher":{"@id":"https:\/\/www.coldjet.com\/es\/#organization"},"articleSection":["Sin categorizar"],"inLanguage":"es","potentialAction":[{"@type":"CommentAction","name":"Comment","target":["https:\/\/www.coldjet.com\/es\/resources\/hill-air-force-base\/#respond"]}]},{"@type":"WebPage","@id":"https:\/\/www.coldjet.com\/es\/resources\/hill-air-force-base\/","url":"https:\/\/www.coldjet.com\/es\/resources\/hill-air-force-base\/","name":"Air Force base quickly and safely removes sealant from F-16 jet wing -
