Tower Hall Funabori), Tokyo, Japan, Focus boom occurs when a flight vehicle accelerates or maneuvers at supersonic speed and its overpressure increases with a factor of three in comparison with an ordinary sonic boom. As a result, upcoming supersonic transport(SST) will be likely to be restricted its flight conditions. This paper presents the effects of several sonic boom waveforms and flight conditions on the peak overpressure of the focus boom. The authors have developed a focus boom prediction program named FFnoise, which combines a splitting scheme and multi-grid like acceleration, resulting in a remarkable speed of solving nonlinear Tricomi equation with sufficient accuracy. The predictions by FFnoise show the competitiveness of the low-boom waveform not only on steady but also on unsteady flight conditions., 形態: カラー図版あり, Physical characteristics: Original contains color illustrations, 資料番号: AA0062268004, レポート番号: JAXA-SP-13-011},
