A study of the aerodynamic design for the reduction of sonic-boom is conducted by a numerical optimization method. The design method combines a three-dimensional Euler CFD (Computational Fluid Dynamics) code with a least-square optimization technique. The fuselage geometry of an aircraft is modified by the method in order to minimize the pressure discrepancy between a target low-boom pressure signature and a calculated near-field pressure signature. The results of the study indicate that the aircraft configuration designed by the method can generate the low-boom pressure signature.
