Abstract摩擦抵抗を低減するため自然層流翼設計が小型超音速旅客機QSSTに対して適用された。設計対象は, マッハ数1.6, 50人乗りを想定したJAXAの概念設計の参照機体である。自然層流設計システムのいくつかの部分が, 高い空力性能を達成するために改善された。下面の目標圧力分布を修正した結果, 全抵抗, すなわち摩擦抵抗だけでなく圧力抵抗も改善された。
Natural laminar flow wing design was applied to the small supersonic transport QSST by using a computational fluid dynamics based supersonic inverse design method, aimed to reduce friction drag. The design target is a small supersonic passenger aircraft (Mach 1.6, 36-50 passengers), which is a reference airframe for JAXA's conceptual design. In this study, some parts of the natural laminar flow design system were improved in order to achieve high aerodynamic performance. The total drag, i.e. not only the friction drag but also the pressure drag, was improved by this modification of the target pressure distribution of the lower surface.
