【摘要】 对单级入轨运载器气动布局进行了研究,设计了一种翼身融合体气动布局,并进行了布局优化。计算结果表明该布局在Ma=6的时候,最大升阻比Kmax可以达到3.755,从高速到低速都能维持在4左右。通过与已有乘波体方案的对比,表明新设计的翼身融合体是一种很有潜力的单级入轨运载器气动布局可选方案。更多还原

【Abstract】 A blended wing-body configuration for SSTO(single-stage-to-orbit)vehicles was developed and a CFD analysis of the configuration was conducted in this paper.Several conclusions can be drawn: Firstly,the maximal lift-drag ratio Kmax=3.755 is obtained at Mach number Ma=6;Secondly,the lift-drag ratio Kmax is maintained around 4 at speeds ranging from subsonic to supersonic.Finally,the feasibility of the wing-body configuration is discussed in detail by comparing it with a waverider configuration which was designed before and it is shown that this wing-body configuration is a potential and practicable aerodynamic concept for SSTO vehicles.更多还原
