| Abstract: | Sonic boom has become the most critical technology limiting civil aircraft's supersonic flight over land.To realize sonic boom reduction for supersonic aircraft,thus making supersonic flight over land available,will bring a huge potential market.Based on the SGD(Seebass-George-Darden) method,a procedure involving inverse design has been set up,which allows for complete analysis of lower sonic boom and aerodynamic performance.A shuttle configuration is developed for the first time.The results reveal that the... |
