(1) A high performance aerodynamic device which utilizes supersonic multi element aerodynamics has been proposed. Biplane wings have been researched using computational fluid dynamics (CFD). Those wings realize almost drag-less performance by utilizing favorable interaction between pressure waves of two wing elements. Through the research in 2005 and 2006 years, one of the best biplane airfoil was designed. It has sufficient lift for the cruise with the speed of Mach 1.7 and the lift-drag ratio (l/d) is 21. This is the first time in the world to show that a lifted biplane can have such a high l/d performance. In 2007, biplane wings has been investigated by extending the designed airfoil to a three dimensional device. It has been also confirmed that an airfoil/wing design system, which has been developed in this project, works efficiently and accurately for the both of 2D and 3D design problems.(2) Detailed CFD analysis about multi body problems in a subsonic flow-field has been conducted A flow-field around aircraft has been simulated at the Mach number of 0.2. The configuration consists of a fuselage, an engine nacelle and a wing which has a slat and a flap in extended condition. Basic flow equations are Reynolds averaged Navier-Stokes ones. There occur many interactions between a slat and a main-wing, a wing and a nacelle etc. Therefore, the flow phenomena must be complicated. we intended to obtain useful data to model aerodynamic interaction. The computations have been conducted using grid distribution as high density as possible. At the present, qualitatively we have obtained reliable data. However, for the detailed analysis, the current resolution level is not sufficient. It is needed to devise advanced numerical techniques to analyze separated flow-fields, vortices and free sheer layers.

（1）提出了使用超音速多元元件空气动力学的高性能空气动力设备。已经使用计算流体动力学（CFD）研究了双翼飞机机翼。这些机翼通过利用两个机翼元件的压力波之间的有利相互作用来实现几乎无拖放的性能。通过2005年和2006年的研究，设计了最好的双翼飞机机翼之一。它具有足够的升降机，以1.7马赫的速度进行巡航，升力拖拉比（l/d）为21。这是世界上第一次表明提起的双翼飞机可以具有如此高的L/D性能。 2007年，通过将设计的机翼扩展到三维设备，对双翼飞机的翅膀进行了研究。还已经确认，该项目中已经开发的机翼/机翼设计系统可为2D和3D设计问题有效，准确地工作。（2）详细的CFD分析，详细介绍了亚音速流中多体问题已经在飞机周围进行了一个田间，以0.2的马赫数模拟了飞机。该配置由机身，发动机固定式和机翼组成，该机翼的侧面有板条和襟翼。基本流程方程是雷诺平均的Navier-Stokes。板条和主翼，翅膀和纳塞尔等之间发生了许多相互作用。因此，流动现象必须复杂。我们打算获取有用的数据来对空气动力学相互作用进行建模。这些计算是使用尽可能高的网格分布进行的。目前，我们已经获得了可靠的数据。但是，对于详细分析，当前的分辨率级别还不够。需要设计高级数值技术来分析分离的流场，涡流和自由透明层。
