However, in supersonic flights, we face the problem of 'sonic boom', which is induced by a shock wave. To alleviate the problem of sonic boom, the idea of reducing shock wave using Busemann biplane has been proposed. The interaction of shock waves between the two wings cancels out or reduces the shock waves created by individual wings. This research discusses two issues about Busemann biplane. One is the unstarted condition during acceleration. The other is the three-dimensional configuration of Busemann biplane. Unstarted condition happens due to the unsatisfied condition with Kantrowitz Donaldson Criteria. Unstarted condition that holds in the criteria is confirmed by analyzing accelerate phenomenon using Computational Fluid Dynamics (CFD) analysis. The other important issue is that the shock front should be planar to cancel out the shock waves between two wings. The caret wing induces a planar shock front. Three caret wing configurations are analyzed to examine how the planar shock front are created using CFD analysis., 資料番号: AA0063154019, レポート番号: JAXA-SP-06-010}, pages = {101--106}, publisher = {宇宙航空研究開発機構, Japan Aerospace Exploration Agency (JAXA)}, title = {複葉超音速翼空力設計の現状と課題}, volume = {JAXA-SP-06-010}, year = {2006} }
