A vehicle based on WIG (Wing In Ground effect) is expected as one of the candidates of future high speed vessels on seaway. As the first study, the shape optimization problem of 2D (2 dimensional) WIG is discussed as a fundamental study with respect to WIG.For this purpose, the panel method is used for the fluid flow analysis around WIG and the nonlinear programming is used as the optimization method. Numerical examples are shown for several optimization problems. An optimized wing section of WIG is tested to verify its aerodynamic characteristics by using an experimental method of WIG devised for a small wind tunnel. As the second problem, Morino's panel method is applied to aerodynamic analyses around a Ram-wing type 3D WIG with special reference to aerodynamic characteristics of its side end plates. Under the consideration of these analyses, aerodynamic shape optimization problems of Ram-wing type WIG are discussed. Numerical examples of optimized wing section are shown, in which the optimizations are carried out by means of the aerodynamic analysis based on the panel method and the nonlinear programming. In both problems, SQP (Sequential Quadratic Programming) technique is used as the optimization method, which is very useful to get the optimum solution under several complex design constraints.

预计基于假发（地面效应的机翼）的车辆是海道未来高速船只的候选者之一。作为第一项研究，将2D（2维）假发的形状优化问题讨论为关于假发的基本研究。为此，将面板方法用于假发周围的流体流量分析，非线性编程用作用作非线性编程优化方法。显示了几个优化问题的数值示例。测试了假发的优化机翼部分，以使用为小风洞设计的假发方法来验证其空气动力学特性。作为第二个问题，将摩里诺的面板方法应用于围绕木翼型3D假发的空气动力学分析，并特别提及其侧板的空气动力学特征。在这些分析的考虑下，讨论了撞翼假发的空气动力学优化问题。显示了优化机翼部分的数值示例，其中通过基于面板方法和非线性编程的空气动力学分析进行了优化。在这两个问题中，SQP（顺序二次编程）技术都用作优化方法，这对于在几个复杂的设计约束下获得最佳解决方案非常有用。
