摘要
针对高隐身超声速无尾布局飞机设计技术、无尾布局增稳及控制措施设计技术、高隐身超声速无尾布局气动隐身耦合设计技术,以及扁平化布局进排气一体化设计技术等内容,开展了多目标优化设计和研究。基于传统飞翼布局设计思想,采用多种先进布局设计手段,完成了无尾飞机总体布局概念方案设计和数值仿真。通过对机身前体形状、前体侧向投影面积、前体水平投影面积,以及推进系统后体壁面扩张比开展多轮参数敏感性分析,建立了关键部件参数化设计准则,并完成了机翼后缘操纵舵面设计。通过阻力舵面的布置基本解决了扁平化前体导致的纵向力矩上仰问题,形成了高隐身超声速无尾布局设计方法,可为工程中无尾布局飞机气动隐身综合设计工作提供参考。
This paper researches the design and optimization of the high stealthy supersonic tailless aircraft,which concentrates on the overall design,methods of improving the stability and controlling performance,coupling of aerodynamic-stealthy performance and integrated design of flat layout and inlet-exhaust system. The research,based on the traditional flying-wing aircraft,has completed the overall design and numerical simulation of a tailless aircraft through a lot of advanced design methods. It established a principal of parameters design aimed at critical components by studying the effect of the forebody’s shape,the vertically and horizontally projected area and the expansion of the afterbody on the aerodynamic performance of the aircraft. Then the design of control surfaces at the trailing edge is accomplished. The control surfaces solved the problem of pitching moment going up,which is troublesome for designers of the flat layout. Finally,the design method of the high stealthy supersonic tailless aircraft is summarized,which can be a frame of reference for aerodynamic-stealthy design in the field of aeronautical engineering.
