GE Aviation anticipates the first GEnx engines installed with the new brackets will be shipped in January 2019.<\/span><\/p>\n<p style=\"margin-bottom:.0001pt\">&nbsp;<\/p>\n<p style=\"margin-bottom:.0001pt\"><span style=\"line-height:normal\">GEnx-2B commercial airline engines power the Boeing 747-8. The PDOS is used on the ground to open and close the fan cowl doors to enable access to the fan compartment for maintenance reasons. The original PDOS brackets on GEnx-2B engines were produced from a solid block of metal, using conventional methods such as milling; this technique resulted in around 50% of the material being wasted.<\/span><\/p>\n<p style=\"margin-bottom:.0001pt\">&nbsp;<\/p>\n<p style=\"margin-bottom:.0001pt\"><span style=\"line-height:normal\">Using Laser Beam Powder Bed Fusion (LB-PBF) additive technology (referred to by GE as Direct Metal Laser Melting) to manufacture the new brackets, waste generated during the part\u2019s manufacture has been reduced by as much as 90%. GE Aviation stated that it has also improved the design to reduce the bracket\u2019s weight by 10%. In addition, the decision to mass produce using a cobalt-chrome alloy over a traditional nickel-based superalloy has enabled a faster build. To make this approach as efficient as possible, GE stated that four brackets will be printed at the same time.<\/span><\/p>\n<p style=\"margin-bottom:.0001pt\">&nbsp;<\/p>\n<p style=\"margin-bottom:.0001pt\"><span style=\"line-height:normal\">Using a custom interlocking design to house all four brackets on a single build plate, the Concept Laser M2 cusing machine\u2019s pair of lasers can additively manufacture an aircraft\u2019s worth of brackets in one build, before post-processing and inspection. Finally, by taking production of the brackets entirely in-house, GE Aviation also expects to reduce its production costs.<\/span><\/p>\n<p style=\"margin-bottom:.0001pt\">&nbsp;<\/p>\n<p style=\"margin-bottom:.0001pt\"><span style=\"line-height:normal\"><a href=\"http:\/\/www.ge.com\/additive\" target=\"_blank\" rel=\"noopener\">www.ge.com\/additive<\/a><\/span><\/p>\n<p style=\"margin-bottom:.0001pt\">&nbsp;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>GE Aviation, Cincinnati, announces that the Federal Aviation Administration (FAA) has given \u2018change in design\u2019 approval to GE Additive and GE Aviation to replace a conventionally manufactured power door opening system (PDOS) bracket, used on GE Aviation\u2019s GEnx-2B commercial airline engines, with an additively manufactured bracket.<\/p>\n","protected":false},"author":63082,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"footnotes":""},"categories":[444,440,441,1],"tags":[],"class_list":["post-8039","post","type-post","status-publish","format-standard","hentry","category-aerospace-and-defense","category-news","category-news-articles","category-uncategorized"],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v27.9 -
