| 摘 要： | 在高隐身布局设计研究中,为追求隐身特性,往往会损失部分气动效率。为更好地兼顾隐身特性和气动特性,通过对融合式布局的前缘进行修型,提出一种低阻高隐身前缘布局。对三种不同机身布局进行雷达散射特性和气动特性建模计算,得出修型后布局雷达散射截面降低,且波峰波瓣很窄,同时在气动上提高了升阻比,减小了配平损失,从而较大地提高了气动效率。

| Abstract: | In the research of high stealth performance layout designing, the pursuit of high stealth often cause aerodynamic efficiency decrease. This essay submit a leading edge layout with low resistance and high stealth by modifying the leading edge of blended body. By modeling and calculating the radar scattering characteristics and the aerodynamic characteristics of three different fuselages layout, the conclusion is drawn that the RCS of the modified layout is reduced with narrow wave crest, Meanwhile, the lift- drag ratio of the modified layout is improved, and the triming loss is reduced, thus it will greatly improve the aerodynamic efficiency. |
