      • Inverse Design and Analysis of Supersonic Biplane

        With the aim of realizing a new concept of supersonic transport, aerodynamic wing design and analysis are discussed based on Computational Fluid Dynamics. A biplane airfoil originated by A. Busemann was extended to 3-D wings with a design Mach number of 1.7. Euler simulations of several biplane wing configurations were conducted. Due to the existence of wing tips, biplane wings do not perform as well as biplane airfoils. This is because the wingtip areas are affected by the three dimensionality of Mach cone integration of influenced areas. The three-dimensionality precludes the occurrence of an appropriate pressure wave interaction. Induced drag due to lift is also generated there. Thus, the wingtip area has a large drag coefficient. To overcome these problems. a tapered wing was herein considered. Then, Aerodynamic design of wing section shapes of the tapered biplane wing was conducted using a recently devised inverse problem method. The designed biplane wing shows a better lift-to-drag ratio performance than the 2-D flat-plate airfoil in the range where the lift coefficient is more than 0.17. In addition, some desirable pressure wave interaction phenomena were found in the three dimensional biplane.
