抄録

A vehicle based on WIG(Wing In Ground effect)is expected as one of the candidates of future high speed vessels on seaway. In the former part of the present study, 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 WIG are discussed in the latter part of this paper. 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 technique based on SQP(Sequential Quadratic Programming)
