Because of fabrication, materials, and geometric uncertainties, a statistical approach combined with Multidisciplinary Design Optimization (MDO) is used to modify key model parameters. Static test data collected using photogrammetry are used to correlate with model predictions. Results show significant improvements in model predictions after parameters are updated; however, computed probabilities values indicate low confidence in updated values and\/or model structure errors. Lessons learned in the areas of wing design, test procedures, modeling approaches with geometric nonlinearities, and uncertainties quantification are all documented.\u003cbr\u003e\u003cbr\u003e\u003cb\u003eAuthor:\u003c\/b\u003e Nasa Technical Reports Server (Ntrs)\u003cbr\u003e\u003cb\u003eISBN-10:\u003c\/b\u003e 1287269451\u003cbr\u003e\u003cb\u003eISBN-13:\u003c\/b\u003e 9781287269458\u003cbr\u003e\u003cb\u003ePublisher:\u003c\/b\u003e Bibliogov\u003cbr\u003e\u003cb\u003eLanguage:\u003c\/b\u003e English\u003cbr\u003e\u003cb\u003ePublished:\u003c\/b\u003e 07\/31\/2013\u003cbr\u003e\u003cb\u003ePages:\u003c\/b\u003e 22\u003cbr\u003e\u003cb\u003eFormat:\u003c\/b\u003e Paperback\u003cbr\u003e\u003cb\u003eWeight:\u003c\/b\u003e 0.13lbs\u003cbr\u003e\u003cb\u003eSize:\u003c\/b\u003e 9.69h x 7.44w x 0.05d","brand":"Nasa Technical Reports Server (Ntrs)","offers":[{"title":"Paperback","offer_id":47611324891391,"sku":"9781287269458","price":14.75,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0662\/2982\/9887\/files\/img_9abe4fbe-81cd-4202-879f-ddaff700fdf8.jpg?v=1764513164","url":"https:\/\/www.whiterainbookhouse.com\/products\/model-update-of-a-micro-nasa-technical-reports-server-ntrs-9781287269458","provider":"WR Book House","version":"1.0","type":"link"}
