Technical Report of National Aerospace Laboratory: An Aerodynamic Design Method for Generating Low Sonic-Boom Pressure Signatures.

摘要

A study was conducted of an aerodynamic design for the sonic-boom reduction of supersonic transport. Sonic-boom is one of the most important environmental problems for supersonic transport and many methods for the reduction of sonic-boom intensity have been published. A new low sonic-boom design method is proposed in this study in order to deal with the nonlinear effects of the strong shocks near the aircraft and the three-dimensional effects of the aircraft configuration unable to be taken into account in the F-function method. This new low sonic-boom design method combines a three-dimensional Euler CFD code with a least-square optimization technique.
