Split Tip Wingletの多分野統合最適設計と次元削減手法による設計知見の抽出

抄録

In this paper, we describe multi-disciplinary optimization (MDO) of a split-tip winglet (STW) model for the TRA2012A commercial jet aircraft model. The STW configuration is expressed by attaching a small wing under the main winglet. The onboard fuel weight, main wing structure weight and the sum of these weights are objective functions, and are minimized respectively in a fixed aircraft operating range for the MDO. The independent component analysis is applied to non-dominated optimal designs obtained from the MDO, and then dominant shape deformation modes are extracted. Design knowledge to improve multi-disciplinary performance is investigated from the modes.
