IVLM is a tool to calculate the circulation distribution which achieves the minimum induced drag for each wing configuration mathematically. It is based on Kroo's method which is using Lifting Line Theory. IVLM takes effects of sweep back angle and airfoil camber into consideration by applying VLM. In this study, IVLM validity is confirmed through evaluating span loadings of rectangular wings and swept back wings with and without winglets. The characteristic of IVLM is also examined and it is indicated that equal intervals are required for spanwise panel divisions to calculate proper twist and lift distributions., 形態: 図版あり, Physical characteristics: Original contains illustrations, 資料番号: DS1740386005}, pages = {31(31)--38(38)}, title = {渦格子法を用いたスパン方向揚力分布の最適設計手法の検証}, volume = {66}, year = {2018} }
