Abstract: 采用自主开发的数值软件SPACER对典型气动布局在Ma=6.0(Re=1×10~7)高超声速巡航时的气动力性能进行了数值评估。评估的气动布局包括类乘波体(仿X-51A)、翼身融合体(仿ISR)、传统升力体(仿X-33)和轴对称锥形体(仿Fasthawk导弹)。由于升力体范围较广,还对一种相对扁平的升力体模型进行了数值评估。评估结果表明:在考察条件下,类乘波体具有较大的升阻比和较小的阻力,是很有潜力的高超声速巡航气动布局;翼身融合体和传统升力体需一定的改进和进一步的研究,如扁平升力体的气动性能可得到大幅提升;轴对称锥形体以其总阻力小,也具有一定优势。
English Abstract: The aerodynamics of typical aircraft configurations under Ma=6.0 (Re=1×107) cruise condition was evaluated numerically using in-house software SPACER. The configurations include quasi-waverider (like X-51A), blended-wing-body (ISR), traditional lifting-body (X-33) and axisymmetric cone (Fasthawk). A flat lifting-body model was also studied in this paper. It is found that, at the current conditions, the quasi-waverider has good lift-to-drag ratio and relatively small drag force, which is the most potential hypersonic configuration among studied; the blended-wing-body and lifting-body require modifications to improve the performance, such as to flat the shape of the lifting-body; the axisymmetric cone is also a candidate for hypersonic cruise configuration due to the small drag.
