音爆已经成为限制民用飞机在陆地上空进行超声速飞行最关键的因素。降低超声速客机的音爆水平,使其能够在陆地上空超声速飞行,将会给超声速客机带来巨大的潜在市场。基于SGD(Seebass-George-Darden)方法,构建了相关的设计分析环境,对超声速客机低音爆布局的反设计技术作了研究分析,在此基础上首次提出了一种“梭式”布局静音超声速客机方案。计算分析表明,“梭式”布局较好地兼顾了低音爆的设计要求和气动的设计要求,升力面沿机身纵向均衡配置以及双S形前机身都有利于降低音爆,为新一代低音爆超声速客机的设计提供了有益的参考。
Sonic boom has become the most critical factor limiting the supersonic flight of civil aircraft over land. Reducing the sonic boom level of supersonic airliners so that they can fly supersonic over land will create a huge potential market for supersonic airliners. Based on the Seebass-George-Darden (SGD) method, the related design and analysis environment is constructed and the anti-design technique of bass burst for supersonic passenger aircraft is analyzed. Based on this, a “shuttle” layout is proposed for the first time Silent supersonic passenger aircraft program. The calculation and analysis show that the “Shuttle” layout better balances the design requirements of the bass burst and the aerodynamic design requirements. The vertical configuration of the lift plane along the fuselage and the double S-shaped front fuselage are beneficial to reduce the sonic boom. A new generation of bass supersonic supersonic aircraft design provides a useful reference.
