摘　　要：比较分析了某小展弦比飞翼布局作战飞机与典型的常规布局战斗机F16在亚、跨、超声速范围的气动特性,相对而言,飞翼布局飞机具有较大的升阻比和较低的翼载荷。计算并分析了该飞翼布局作战飞机与F16在垂直机动面内的平飞加速性能和跃升性能,得到了由于布局和气动特性不同引起的飞翼布局作战飞机机动性的新特点。研究结果对飞翼布局作战飞机的设计和作战使用均具有一定的参考意义。Subsonic, transonic and supersonic aerodynamic characteristics of a flying wing fighter with small aspect ratio were compared with conventional fighter F16. Flying wing aircraft feature relatively high lift/drag ratio and low wing loading when compared to conventional aircraft. Level acceleration and dynamic ascend performance of this flying wing fighter were also discussed in this paper, which was also compared with F16. Therefore the maneuverability features of the flying wing fighter were reached as the difference of configuration and aerodynamics. The research result can be used in the design and campaign of flying wing fighter.
