Recently various low boom configurations are being suggested. In the present study, a Genetic Algorithm (GA) has been applied to aerodynamic shape optimization of an axisymmetric nose (forebody) geometry. The peak overpressure of sonic boom is obtained from an extrapolation of the nearfield pressure signatures with the waveform parameter method. The drag of designed object is calculated based on the pressure distribution along the body surface, which is obtained by solving the Euler equations. In order to reduce the number of function evaluations by CFD (Computational Fluid Dynamics) up to the global optimal solution, a method by the use of approximated functions is proposed.","subitem_description_type":"Other"}]},"item_5_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号:
