Design of inward turning inlet with simultaneous control of intake axial and horizontal projections

  • 摘要: 为了满足两侧进气布局高超声速飞行器乘波前体与进气道一体化设计要求,基于特征线法和流线追踪技术提出了一种进口轴向投影和水平投影同时可控的内收缩进气道设计方法。采用该方法设计了进口轴向投影和水平投影均为超椭圆的内收缩进气道并在设计点(马赫数为6.0)对其进行数值仿真验证。结果表明:进气道进口轴向投影和水平投影均符合预期设计。进气道能保持基准流场的波系结构和沿程压力分布,无黏时可以全捕获来流,喉道截面性能与基准流场基本相等。有黏时,进气道也具有较高的压缩效率,流量系数和出口总压恢复系数分别为0.96和0.56。因此,上述设计方法可行有效。
