Toyama International Conference Center), Toyama Japan, Multidisciplinary design optimization (MDO) is a practical key technology for the design of a supersonic transport (SST). The computational cost of MDO including aerodynamic design, however, should be expensive with high-fidelity CFD simulations. Therefore, surrogate models, such as response surface method or Kriging method are promising techniques for efficient MDO. Nevertheless, the computational cost will be still expensive to conduct the MDO using a surrogate model in practical time period because a lot of CFD calculations are required for global search. In this study, a fusion of the database with a low-cost/ low-fidelity solver and a high-cost/ high-fidelity solver in the Kriging model is considered to develop a more efficient global exploration method. A test problem with mathematical equation models and a practical aerodynamic design problem of a supersonic wing are carried out to investigate the efficiency of the proposed method. In t""" he supersonic wing design, a linear panel method and a structured Euler CFD solver are employed as a low-fidelity and a high-fidelity solver, respectively. As a result, the total computational cost is drastically reduced with the multi-fidelity method while the same optimum solutions can be explored as those with a single-fidelity optimization., 形態: カラー図版あり, Physical characteristics: Original contains color illustrations, 資料番号: AA0061958037, レポート番号: JAXA-SP-12-010},
