This method can consider a nonlinear and a three-dimensional effects of aircraft which cannot be considered by previous low-boom design methods based on linear theory. The fuselage geometry of a low-boom aircraft designed by linear theory is modified by this design method in order to minimize the pressure discrepancies between a target low-boom pressure signature and a calculated signature. It is shown that the sonic-boom intensity of the aircraft designed by this method is smaller than that designed by linear theory. The results of the study indicate that this method is a useful tool for low-boom design., 資料番号: AA0063609016, レポート番号: JAXA-SP-06-029E}, pages = {124--127}, publisher = {宇宙航空研究開発機構, Japan Aerospace Exploration Agency (JAXA)}, title = {Low sonic-boom design using numerical optimization}, volume = {JAXA-SP-06-029E}, year = {2007} }
